In two-pack high-solids epoxy anticorrosive primers applied to blast-cleaned SA 2½ carbon steel, NOVARES TS140 is assessed as a partial co-binder at 3–7 wt% on total resin solids. Because the resin combines an aromatic core with aliphatic modification, its incorporation alters wetting behaviour on low-energy metallic substrates and shifts the balance between salt-spray resistance and crosswise flexibility. Compliance is anchored to ISO 12944-5:2019 for protective paint systems in corrosivity categories C4 and C5, with supplementary testing under ISO 9227:2017 neutral salt spray and ISO 6270-1:2017 continuous condensation. Formulating at 5 wt% on solids requires a corresponding reduction in the main epoxy resin rather than an addition on top of an already optimised formulation; otherwise the PVC/CPVC relationship can be pushed into a high-stress state during scribe-creep exposure. Production-scale mixing uses a high-speed disperser with a Cowles blade tip speed of 15–20 m/s for the grind phase, followed by bead milling to a Hegman grind of ≤15 µm. The let-down is performed under slow sweep agitation to avoid destabilising the polyamide or amine adduct curing agent. Terminal finished goods include zinc phosphate epoxy primers, high-build epoxy micaceous iron oxide intermediate coats, and blast-primer tie coats for multi-coat systems in industrial maintenance.
On twin-shaft dispersers with independently driven slow-speed scrapers, batch-to-batch viscosity variance is reduced when NOVARES TS140 is pre-dissolved in a coupled aromatic/aliphatic solvent at 60–70 °C before transfer to the mill base. If solid flake is added directly into a high-speed disperser without preheating, undissolved resin particles may survive the grind stage and produce cratering during airless spray. Incompatibility is observed in low-KB aliphatic diluents below 30 °C, where the aromatic portion can form a persistent haze. The viscosity response is non-linear: at 3 wt%, the Stormer viscosity of a typical 85 vol% solids primer may shift by 3–5 KU, while at 7 wt%, the shift can exceed 12 KU, requiring adjustment of the polyamide hardener level to maintain pot life above 45 min. Pull-off adhesion per ASTM D4541-17 after salt spray is typically retained when the coating is applied at 75–125 µm dry film thickness, but sag resistance on hot vertical steel should be confirmed with ASTM D4400-18 at slab temperatures above 40 °C.
On a two-coat coil coating line running at 120 m/min, NOVARES TS140 is introduced into polyester topcoats and backers at 2–5 wt% on total solids to modify hardness, recoat adhesion, and overbake tolerance. The relevant compliance framework is the EN 13523 series for coil-coated metals: EN 13523-0:2021 for general principles, EN 13523-5:2014 for resistance to cracking on rapid deformation, EN 13523-7:2014 for solvent rub resistance, and EN 13523-14:2014 for chalking. Under EU REACH and RoHS 2011/65/EU, standard registration obligations apply. The film is applied by reverse roller coater at 18–22 µm dry film thickness, followed by oven curing at a peak metal temperature of 216–232 °C with a dwell of 30–40 s. Terminal finished product types include polyester exterior building panels, appliance side panels, metal cladding, and backing coats for insulated sandwich panels.
| NOVARES TS140 loading on solids | T-bend flexibility, EN 13523-5 | MEK resistance, EN 13523-7 | Δb* after 30 min at 232 °C, ISO 7724-3 | 60° gloss retention, EN 13523-2 |
|---|---|---|---|---|
| 0 wt% | 0.5 T | 50–60 double rubs | 0.2–0.4 | 88–92 % |
| 2 wt% | 0.5–1.0 T | 60–70 double rubs | 0.3–0.6 | 86–91 % |
| 5 wt% | 1.0–1.5 T | 70–80 double rubs | 0.7–1.2 | 82–87 % |
The aliphatic modification limits yellowing compared with unmodified aromatic resins, but at peak metal temperatures above 232 °C the colour shift can exceed Δb* 1.0 at 5 wt%, which is typically unacceptable for bright white topcoats. Direct food-contact status must be verified separately under EU 10/2011; use in exterior coil coatings does not automatically imply compliance with food-contact migration limits. On high-speed coil lines, the resin portion that remains at the surface can reduce die-lip build-up, but line trials are required because published data for this specific configuration is limited.
Marine ballast tank formulations based on two-component coal tar-free epoxy use NOVARES TS140 at 2–4 wt% on total solids to modify water uptake and edge retention without introducing free isocyanate. The governing specification is the IMO PSPC MSC.215(82) performance standard for protective coatings for dedicated seawater ballast tanks, together with ASTM D570-22 for water absorption, ISO 2812-2:2018 for immersion resistance, and ISO 4624:2016 for pull-off adhesion. Application on block stages uses plural-component airless spray equipment with a 45:1 pump ratio and tip sizes of 0.019–0.025 in; stripe coating is applied to edges, welds, and penetrations before full spray passes. The environment is controlled to <85 % RH with steel temperature at least 3 °C above dew point. Finished product types include light-coloured ballast tank coatings, immersion-zone epoxy linings for water treatment vessels, and high-solids edge-retentive primers for shipyard block assembly. At 4 wt%, viscosity increase can be significant at 5 °C; therefore winter shipyard application requires heated plural-component lines and reduced tip size to maintain fan pattern stability.
A single-pack alkyd enamel that is reformulated with NOVARES TS140 at 5–10 wt% on total solids is produced by high-speed disperser pre-dispersion of the resin in white spirit or a low-aromatic solvent blend at 40–50 °C, followed by bead milling to ≤20 µm and let-down with oxidative alkyd, metallic driers, and anti-skinning agents. The applicable compliance baseline is ISO 12944-5:2019 for low corrosivity category C3 environments, with drying evaluated under ASTM D1640-14, gloss under ASTM D523-14, and accelerated weathering under ASTM D4587-11. Terminal product types include single-pack alkyd topcoats for structural steel, machinery enamels, and general metal maintenance enamels. Through-dry can be delayed if the resin is used above 10 wt% because the higher aromatic fraction reduces oxygen diffusion into the drying film; dry-to-handle may remain short, but through-hardness should be confirmed by pendulum damping or indentation. Long-term exterior exposure may increase chalking rate relative to an unmodified alkyd, and published data for this specific alkyd configuration is limited, so the upper addition level should be validated on the target steel substrate under ISO 9227:2017 before specification.
For two-component acrylic polyurethane topcoats applied to structural steel, NOVARES TS140 is introduced at 2–4 wt% on total solids to increase low-shear viscosity and reduce sag on vertical surfaces without requiring a separate thixotrope. Compliance is assessed within a multi-coat system under ISO 12944-6:2018, with viscosity measured by ASTM D4287-00 at 10 000 s⁻¹, sag resistance by ASTM D4400-18, and gloss by ASTM D523-14. The mixed material is sprayed through plural-component airless equipment with a 45:1 pump ratio and 0.013–0.017 in tips at hardener NCO:OH ratios near 1.05:1. Finished product types include aliphatic polyurethane finish coats for chemical plants, bridges, and offshore topside structures. The addition must be controlled tightly: below 2 wt% the sag-control effect is marginal, while above 4 wt% the spray viscosity can exceed 90 s on DIN cup 4 mm, forcing a reduction in application solids and increasing VOC. Recoat windows should be revalidated because the resin can alter surface energy after overnight cure in humid coastal environments.
On metal packaging lines using sheet-fed offset and internal lacquer spray, NOVARES TS140 is evaluated in non-food-contact exterior lacquers and decorative base coats at 2–6 wt% on total solids. The compliance position depends on the final article: exterior tinplate decoration must satisfy EN 71-3:2019 only when the article is considered accessible to children, while direct food-contact status requires migration testing under EU 10/2011 and, for United States markets, FDA 21 CFR 175.300 as applicable to resinous and polymeric coatings. Production equipment includes sheet-fed offset presses for printed base coats, followed by internal lacquer spray chambers and gas-fired ovens operating at 180–200 °C with residence times of 10–15 min. Terminal product types include decorative tinplate can exteriors, aerosol can bodies, and non-food closure coatings. Because the resin may influence overprint varnish adhesion, scuff resistance should be checked with ASTM D5264-98 after steam retort simulation if the decorated article is intended for pasteurised or retorted non-food contents.

NOVARES TS140, an aliphatic-modified aromatic hydrocarbon resin supplied as flakes or pastilles, is used as a hard co-resin and binder modifier in solventborne industrial coatings. The numerical suffix identifies a nominal ring-and-ball softening point of 140 °C; commercial certificates of analysis commonly report a softening point interval of 135–145 °C when tested under ASTM E28 or DIN EN 1427. Technical data sheets list an acid number below 0.1 mg KOH/g by ASTM D974, a Gardner colour in the 6–10 range by ASTM D1544, and a density near 1.09 g/cm³ at 25 °C by ASTM D4052 or DIN EN ISO 1183-1. The aliphatic modification lowers the aromatic solubility parameter relative to unmodified C9 aromatic hydrocarbon resins, improving compatibility with low-Kb aliphatic solvent blends while retaining hardness, water resistance, and chemical resistance from the aromatic backbone.
Solvent tolerance in aromatic hydrocarbon resins is governed primarily by aromaticity, molecular weight, and softening point. In NOVARES TS140, the aliphatic modification shifts the solubility behaviour toward lower polar and hydrogen-bonding contributions, enabling clear or nearly clear solutions in blends of xylene and low-Kb mineral spirits that typically cloud with unmodified C9 resins of equivalent softening point. The exact tolerance threshold depends on solvent composition and resin solids; formulators commonly use a cloud-point titration under ASTM D6038 or an equivalent internal method to establish the critical aromatic content for a given primer or enamel. At resin loadings between 15 wt% and 30 wt% of total binder solids, solution viscosity at 60 wt% solids in a 1:1 xylene/mineral spirits blend is generally lower than that of a C9 aromatic resin of similar softening point, although published data for this specific configuration is limited and lot-to-lot variation requires confirmation against the relevant certificate of analysis.
Because NOVARES TS140 retains a high glass transition and aromatic ring content, it contributes to rapid solvent release in force-dried coatings. Thermogravimetric evaluation under nitrogen at 10 °C/min shows that the resin does not undergo significant weight loss below 200 °C, but coating-level evaporation is controlled by carrier solvent and film thickness, not by resin volatility. Drying-time checks are commonly performed according to ASTM D1640, with through-dry determined by DIN EN ISO 9117-3; pendulum hardness after 7 days at 23 °C and 50 % RH is usually measured under DIN EN ISO 1522 or ASTM D4366. The resin is not a film former by itself; its function is to modify the viscoelastic and solvent-release behaviour of a primary binder such as a medium-oil alkyd, a vinyl-toluene-modified alkyd, or a blended hydrocarbon-alkyd system.
In solventborne alkyd primer and air-drying enamel formulations, NOVARES TS140 is typically introduced during the let-down stage as a pre-dissolved resin cut in aromatic or aromatic/aliphatic solvent blends. Production-scale vessels equipped with high-shear dispersion blades and jacketed temperature control are used to dissolve the resin at 90–120 °C under sealed, low-pressure conditions. A pre-dissolved cut of 50–60 wt% resin solids is commonly preferred to avoid hot, high-viscosity transfer through narrow piping. Once incorporated, the resin increases the glass transition of the dried film, reduces tack, and improves water resistance in alkyd binders. In anti-corrosion primers, replacement of 15–25 wt% of medium-oil alkyd solids with NOVARES TS140 can improve early hardness without reducing flexibility below the limits required for impact testing under ISO 6272-1; however, exact formulation adjustments must be validated against ISO 9227 salt spray exposure and ASTM B117 because barrier properties are sensitive to pigment volume concentration, crosslinker selection, and film thickness.
Compatibility with alkyds is influenced by the resin’s acid number and polarity. Because the acid number is specified below 0.1 mg KOH/g, the resin does not interfere with metal drier systems to the extent that high-acid rosin esters or maleated rosin can. Formulators nevertheless evaluate drier adsorption by through-dry testing under DIN EN ISO 9117-3 and storage stability at 40 °C for 14 days; low shear viscosity is checked after storage using a rotational viscometer in accordance with ISO 2555. Titanium dioxide dispersion is generally maintained when the resin is added as a cut rather than as a solid, and grind stability in high-speed dispersers with peripheral speeds of 18–25 m/s is regarded as acceptable in typical alkyd primer formulas. However, formulators should not infer universal compatibility from softening point alone; the aliphatic modification changes the solubility sphere enough that each solvent blend and primary binder must be checked by visual clarity and retained solution viscosity.
Hot-melt handling of NOVARES TS140 in coil coating, heat-seal, or resin compounding lines involves a narrow processing window. At temperatures above 180 °C, oxidative discoloration and molecular-weight growth can occur if oxygen is not excluded; this is observed on production-scale melt tanks as a progressive shift in Gardner colour from the initial 6–10 range toward darker values and as an increase in filtration pressure across hot-melt filters. The resin should therefore be melted in jacketed vessels with temperature control of ±5 °C and inert gas blanketing. Nitrogen flow rates equivalent to 1–3 vessel volumes per hour are typical for resin melt storage, though published data for this specific configuration is limited. Hold time at peak temperature should be limited to 30 min before transfer to heated, double-jacketed piping; longer residence times are not recommended without validated thermal stability data from the relevant lot.
Gear pumps and positive-displacement pumps with heated heads are preferred for transfer because the melt viscosity below 140 °C increases rapidly and can stall centrifugal or low-torque pumps. The melt viscosity at 180 °C is typically in the range of 500–2500 mPa·s for aromatic hydrocarbon resins of this softening point, but the exact curve for NOVARES TS140 must be taken from the supplier’s melt-viscosity graph generated according to ASTM D3236 or equivalent rotational methods. In-line hot-melt filtration through sintered metal cartridges with absolute ratings of 25 µm or finer is recommended before coating application; pressure differentials above 1.5 bar indicate gel-like aggregates or char, and the line should be flushed with hot aromatic solvent rather than aliphatic solvent to avoid thermal shock and precipitation in the filter housing.
Thermal degradation in aliphatic-modified aromatic resins is not limited to colour; chain extension can shift the ring-and-ball softening point above the original 135–145 °C specification. A production-scale batch held at 210 °C for 60 min under air may show an increase in softening point of 2–5 °C, but this should be confirmed by ASTM E28 because oxygen ingress, surface-to-volume ratio, and trace metal content influence the rate. The resin is supplied as a coating-grade raw material and should not be blended with strong oxidizers or with amine-based drying additives in hot-melt systems due to possible exothermic interactions. Pre-drying is not normally required unless the resin has been exposed to humidity above 60 % RH, in which case surface moisture can cause popping or foaming in open melt vessels.
The functional difference between NOVARES TS140 and conventional hydrocarbon resins is best assessed through aromaticity, softening point, acid number, and solvent compatibility. Unmodified C9 aromatic resins of similar softening point offer higher aromatic ring density, which can improve hardness and chemical resistance in aggressive environments but reduces solubility in low-Kb aliphatic solvents and may increase yellowing tendency. Fully aliphatic C5 resins provide better initial colour and aliphatic solubility but lack the glass-transition contribution and barrier character required in many industrial primers. NOVARES TS140 occupies an intermediate position: the aliphatic modification improves low-Kb solvent tolerance while the aromatic fraction retains a harder, more chemically resistant dried film.
| Parameter | NOVARES TS140 | Unmodified C9 aromatic | C5 aliphatic |
|---|---|---|---|
| Softening point | 135–145 °C by ASTM E28 | grade-dependent, commonly 90–160 °C | grade-dependent, commonly 80–120 °C |
| Acid number | ≤ 0.1 mg KOH/g by ASTM D974 | comparable low-acid hydrocarbon resin | comparable low-acid hydrocarbon resin |
| Aromaticity | aliphatic-modified aromatic | high | low |
| Low-Kb aliphatic solvent tolerance | moderate | limited | high |
| Dried film hardness contribution | high | very high | low to moderate |
| Gardner colour tendency | 6–10 typical by ASTM D1544 | higher than 6 typical | lower than 6 typical |
| Coating function | co-binder and hard resin | hard resin and chemical-resistance modifier | plasticizer, tackifier, and colour-stable extender |
Comparison with rosin ester hard resins is also relevant for alkyd primers. Rosin esters may carry acid numbers of 10–20 mg KOH/g, which can interact with basic pigments and driers; NOVARES TS140 is specified below 0.1 mg KOH/g, reducing that interaction. Against lower-numbered grades in the same modified resin family, the TS140 suffix indicates a higher softening point and therefore a higher melt viscosity and greater hardness contribution, but it generally requires higher dissolution temperatures or a higher proportion of aromatic solvent in the let-down cut. These differences should be verified with solubility maps and viscosity curves rather than extrapolated from unmodified C9 resin data.
For regulatory documentation, NOVARES TS140 is supplied as a solid hydrocarbon resin with low volatile content. Flash point is typically above 200 °C under ASTM D92 or ISO 2592, and the product is not classified as a dangerous good under typical land and sea transport regulations. REACH registration status, RoHS screening, and food-contact suitability must be obtained from the manufacturer because these differ by production site and regional substance evaluation. Users should verify chlorine, sulfur, and phenol content against the lot certificate when specifying the resin for coil coatings or for applications with volatile organic compound restrictions under EU Directive 2004/42/EC.
