Arkema Rilsan Fine Powders 6132 GREY 15-10 FB is a grey-pigmented polyamide 11 (PA11) powder coating consumed as a single-component thermoplastic layer on metal components. The powder can be deposited by electrostatic spray or fluidized-bed dip and is not formulated with a hardener, accelerator, or liquid solvent. The downstream scenarios below are limited to verified PA11 powder-coating sectors where this fine powder grade is specified for corrosion protection, abrasion resistance, impact resistance, and detergent resistance. Test anchors follow published standards from ISO, ASTM, FDA, EU regulatory texts, and IEC, with method designations included where they govern the coating process or finished part.
The most process-intensive use of Arkema Rilsan Fine Powders 6132 GREY 15-10 FB is the coating of girth weld field joints on carbon steel pipelines. In this application, the powder is applied after the factory-applied anti-corrosion layer is cut back, the girth weld is completed, inspected, and abrasive blasted. Surface preparation is specified to at least ISO 8501-1 Sa 2.5, with an angular profile of Rz 50–75 µm measured according to ISO 8503-2. The powder is deposited onto an induction-heated substrate at a metal temperature of 260–300°C. Because the pipe wall acts as a heat sink at the cutback edges, the heating sequence is separated into a preheating pass and a soaking pass; otherwise the film edges freeze before coalescence and holiday formation occurs. The addition ratio is 100 wt% PA11 powder without a crosslinker. After storage above 60% RH, the powder is pre-dried at 70–80°C for 2–4 h in a desiccant dryer, and free flow is restored with 0.05–0.2 wt% fumed silica. The dry film thickness on buried joints is held at 350–500 µm and measured with an eddy current gauge per ISO 2808. Performance qualification for offshore pipeline field joint systems is commonly conducted under NACE SP 0108-2008, and atmospheric corrosivity is classified under ISO 12944-6:2018; where a C5-M environment applies, test durations of 1,440 h under ISO 9227:2022 neutral salt spray are referenced for qualified topcoat systems. Published data for this specific grey FB grade in a stand-alone pipeline joint configuration is limited, and a site-specific qualification coupon is required before production. Terminal finished products are girth weld field joints on onshore gas transmission pipelines, pump station spools, and valve station tie-in spools.
In white-goods manufacturing, grey PA11 powder is applied to steel wire dishwasher baskets by fluidized-bed immersion. The addition ratio is 100 wt% PA11; no primer or adhesion promoter is used on the blasted steel surface. Cut and welded wire baskets are degreased, shot-blasted to ISO 8501-1 Sa 2.5, preheated in a convection oven to 300–340°C, immersed in the fluidized powder bath for 3–6 s, and transferred to a post-fusion oven at 200–220°C for 5–10 min. The fused film reaches a nominal dry film thickness of 250–450 µm. Compliance for food-contact use is anchored to FDA 21 CFR 177.1500 for nylon resins and to EU Regulation 10/2011 for plastic materials intended to come into contact with food, subject to specific migration limit verification at the finished-part stage. Terminal finished products are dishwasher baskets, cutlery holders, and upper-rack wire utensil trays. The operational limitation is continuous wet-heat exposure above 90°C in the dishwasher booster heater zone; coated parts in that zone require separate validation.
Adhesion loss on cast iron components originates from two simultaneous variables: retained foundry moisture in subsurface porosity and residual graphite dust after machining. In this scenario, grey PA11 powder is applied to waterworks ductile iron valve bodies, pump volute casings, and flange protectors. The as-machined castings are degreased, then pre-baked at 180–220°C for 45–90 min to drive off volatile pore water before abrasive blasting. Blasting is performed with angular metallic grit to ISO 8501-1 Sa 2.5, producing a profile of Rz 40–70 µm. The powder is sprayed electrostatically at 60–100 kV corona charging voltage using a Nordson or Gema automatic gun, onto parts at ambient or 40–60°C. The addition ratio is 100 wt% Arkema Rilsan Fine Powders 6132 GREY 15-10 FB; if the powder bed drops below minimum fluidization density, 0.1–0.3 wt% fumed silica is post-added using a high-shear mixer. Fused film thickness is 300–450 µm. Adhesion is verified by cross-cut test per ISO 2409:2020 and pull-off per ISO 16276-1:2007, with pass criteria aligned to the purchaser’s under-film corrosion class. For municipal waterworks exterior exposure classified as ISO 12944-2 C4, neutral salt spray testing follows ISO 9227:2022. Terminal finished products are ductile iron gate valves, check valve bodies, and pump casings installed in coastal water treatment plants. The main incompatibility is residual amine-based foundry core binder on the casting surface, which causes localized pinhole formation during fusing; cores must be burned out to ≤0.1% residual organic content before coating.
A continuous electrostatic spray line coats zinc-phosphated steel fasteners and suspension springs with the grey PA11 powder at an addition ratio of 100 wt%. The line is built around a rotating hook conveyor, a corona spray booth with three automatic guns operating at 60–90 kV, and a direct-fired hot air oven with a 10–14 min dwell. Component metal temperature at oven exit is maintained at 200–230°C. The zinc-phosphate pretreatment provides temporary corrosion protection and increases surface energy; the PA11 layer is applied at 200–350 µm DFT. For underbody fasteners and suspension springs, part-specific salt spray acceptance is assigned by the vehicle manufacturer; the base test method is ISO 9227:2022 neutral salt spray, with scribe creep measured according to ISO 17872:2019. The PA11 layer is also characterized for abrasion resistance under ASTM D4060-19 Taber testing and for direct impact under ASTM D2794-19. Regulatory compliance for automotive supply is anchored to REACH Regulation (EC) No 1907/2006 Annex XVII and RoHS Directive 2011/65/EU Annex II. Powder must be pre-dried at 70–80°C when stored above 60% RH; otherwise gun spitting and reduced transfer efficiency occur. Terminal finished products are suspension coil springs, underbody bracket fasteners, brake hose clip plates, and battery tray bolts. Continuous service above 120°C metal temperature is not recommended; published data for the specific GREY 15-10 FB grade in cyclic automotive corrosion tests is limited.
Surgical stainless steel trays and mobile hospital furniture components are coated batchwise using PA11 powder when repeated impact and detergent resistance are required. The stainless steel surface is first degreased and passivated according to ASTM A967/A967M-17, then preheated to 240–280°C. The powder is applied electrostatically at 50–80 kV and fused to a film thickness of 150–250 µm. The addition ratio is 100 wt% Arkema Rilsan Fine Powders 6132 GREY 15-10 FB; no flow modifier is required on freshly opened batches, but dry-flow additive at ≤0.2 wt% is used only when powder moisture uptake exceeds the manufacturer’s free-flow specification. Process validation for the coating operation falls under ISO 13485:2016, Clause 7.5.6, for validated processes. Biological evaluation is per ISO 10993-1:2018 only for patient-contacting finished devices; for instrument trays that contact intact skin, PA11 is often accepted under the supplier’s chemical characterization, but published data for this specific grade in mucosal or implantable contact is limited. Terminal finished products are surgical instrument trays, case cart shelf clips, wheelchair frames, and hospital bedside table arms. Multiple autoclave cycles above 121°C can induce moisture absorption and dimensional creep in PA11 films; steam sterilization acceptance must be validated per ISO 17665-1:2006 on the coated assembly.
For outdoor telecommunication enclosures fabricated from die-cast aluminum, grey PA11 powder is applied after a chromate-free conversion coating to protect against ultraviolet exposure, salt fog, and mechanical impact. The addition ratio is 100 wt% PA11 powder; if the fluidized bed has been idle in a humid plant, 0.1–0.2 wt% hydrophobic fumed silica is added and the powder is passed through a 75 µm sieve. Aluminum castings are alkaline-etched, conversion-coated per DIN EN 12487:2007, preheated to 220–260°C, electrostatic powder-coated at 60–100 kV, and post-fused at 200–230°C for 5–10 min. The target dry film thickness is 200–300 µm. Outdoor weathering for powder-coated metal enclosures is assessed under ISO 6270-2:2017 condensation testing and ISO 2409:2020 cross-cut adhesion. Vibration and mechanical shock of the finished enclosure follow IEC 60068-2-6:2007. Terminal finished products include railway signal housings, solar inverter cabinet walls, and 5G remote radio unit enclosures. The coating is not recommended for continuous immersion in methylene chloride or concentrated formic acid, and long-term service above 120°C is outside the verified operating window.

Arkema Rilsan Fine Powders 6132 GREY 15-10 FB PA11 is a semi-crystalline polyamide 11 powder supplied for fusion-bonded corrosion protection and wear-resistant coatings on metal substrates. The grade designation encodes the base resin PA11, the fine powder series 6132, the grey 15-10 colour reference, and the FB fluidized-bed-optimized particle-size cut. Published grade-specific data for this exact pigmented FB configuration are limited; the values below are derived from Arkema technical literature for Rilsan PA11 coating powders and from standard test methods, and they require line-specific validation on the intended substrate.

| Salt spray resistance on grit-blasted steel with primer, 250 µm film | ISO 9227 | >1000 h |
Fluidized-bed application of PA11 6132 grey 15-10 FB on production equipment requires simultaneous control of particle size distribution, moisture content, and metal preheat temperature. The FB suffix indicates a particle-size cut that remains in dense-phase fluidization at lower air velocities than coarse rotational-lining powders. Arkema does not always publish the complete D10, D50, and D90 values for pigmented 6132 FB; therefore the air flow must be set on each bed to avoid channelling and slugging. Field observations on production fluidized-bed tanks indicate that PA11 fine powders of this class fluidize acceptably at superficial air velocities in the range 0.3–0.8 m/s when the bed temperature is held below 30 °C. Fluidization air should be dried to a dew point below -20 °C to reduce moisture uptake by the polyamide particles.
Metal preheat is the critical thermal parameter. Carbon steel workpieces are normally heated to 280–330 °C before immersion. Preheat below 260 °C yields incomplete coalescence, low gloss, and poor adhesion; preheat above 350 °C initiates thermal-oxidative yellowing and can embrittle the resulting film. Dwell time in the fluidized bed is typically 2–10 s, followed by a post-fusion oven hold at 180–200 °C for 2–5 min to complete void elimination in thick sections. The final dry-film thickness is generally controlled in the 250–400 µm range for corrosion-critical parts.
Moisture control during storage is equally important. Polyamide 11 absorbs water by hydrogen bonding; powder exposed to relative humidity above 60 % should be dried at 80 °C for at least 4 h in a desiccant-bed dryer before use. Free surface moisture and absorbed water vaporize during preheat and create steam pinholes, especially on cast-iron substrates with graphite flake outgassing. Therefore powder hoppers should be kept sealed under dry air with a dew point below -20 °C and returned powder should not be mixed with fresh powder unless sieved through a 150 µm screen to remove agglomerates.
On a production fluidized-bed coating line, the part is suspended by a grounded jig, preheated in a continuous convection oven, immersed into the fluidized bed, and shaken to remove excess powder. The shaking stroke and frequency are set to avoid striping. For complex parts, a second immersion may be applied after a short reheat; each immersion adds roughly 100–200 µm to film thickness. Drainage and edge coverage are influenced by powder bulk density and fluidization; PA11 powders of this class have bulk densities in the range 0.45–0.55 g/cm³. Film porosity is checked by low-voltage holiday testing at 3–5 kV per ASTM D5162; pinholes can be repaired by flame spraying a small amount of PA11 powder.
Film formation of PA11 6132 grey 15-10 FB occurs by melt coalescence, not by chemical crosslinking. The melting endotherm at 186 °C is only the onset of particle fusion; complete film continuity requires the substrate to remain above the crystallization temperature long enough for bubbles to escape from the melt. Crystallization temperature of PA11 is approximately 160–165 °C under slow cooling; therefore post-fusion cooling should not be forced too rapidly if hardness and solvent resistance are the primary targets. Water quenching or forced-air cooling after removal from the bed lowers crystallinity and increases impact toughness but reduces stiffness and may increase water uptake. This trade-off must be resolved for each part geometry.
Thermal-oxidative stability limits continuous service temperature. Rilsan PA11 coatings can operate continuously at 90–120 °C in dry air, but continuous exposure above 120 °C may reduce elongation due to oxidative chain scission. Short-term excursions above 210 °C should be avoided because yellowing and film embrittlement occur within minutes. Oven temperature profiling should therefore be validated with thermocouples on the thickest and thinnest sections of each workpiece to avoid thermal overshoot.
Blast-cleaning on coating lines typically uses angular chilled iron grit to achieve Sa 2½ per ISO 8501-1, with surface profile 50–75 µm measured by replica tape per ISO 8503-5. After degreasing and phosphating or chromate-free conversion treatment, a PA11-compatible primer is applied at 5–15 µm dry film thickness. Silicone residues from cutting fluids, chlorinated solvent residues, and amine-based surface treatments must be removed because they interfere with wetting and can cause cratering or adhesion loss. Substrates with sharp edges, blind holes, or weld spatter require pre-coating radiusing and cleaning because molten PA11 cannot reflow into recesses after the part is withdrawn from the bed.
Unlike PA12 coating powders, PA11 6132 grey 15-10 FB has a higher melting temperature, which requires an upward preheat offset of 8–12 °C on existing PA12 lines. PA11 typically exhibits lower water absorption than PA6 or PA66 but slightly higher water absorption than PA12; therefore PA11 is selected when low-temperature impact toughness and abrasion resistance are more important than minimum water uptake. The grey 15-10 FB grade differs from natural 6132 by the presence of an inorganic pigment system that may alter melt viscosity and electrostatic charging; consequently, process settings cannot be transferred directly from natural 6132 to grey 15-10 FB without revalidation of bed height, air flow, and immersion time.

Compared to epoxy powder coatings, PA11 6132 grey 15-10 FB is thermoplastic and does not require a cure reaction. This permits post-forming and rehealing of minor damage, but reduces upper use temperature and solvent resistance relative to crosslinked epoxies. It also requires higher preheat. Compared to Rilsan PA11 extrusion grades, 6132 grey 15-10 FB is a cryogenically ground powder with controlled particle shape and cannot be fed directly into injection moulding machines without melt re-compounding. Electrostatic application of this FB grade is possible but limited because larger particles require higher powder gun voltage and may produce orange peel. Electrostatic grades are preferred for film thickness below 150 µm.
Continuous immersion in concentrated sulfuric acid, nitric acid, or oxidizing media at elevated temperature is outside the operational envelope. Strongly alkaline cleaning baths above 80 °C can attack PA11. The powder should not be blended with PA12 or with recycled mixed-polyamide powders because differences in melting temperature and melt viscosity create phase separation and surface defects. Powder handling must comply with ATEX 2014/34/EU and NFPA 654 because fine polymer powders form explosive dust clouds. When line trials involve a switch from natural 6132 to grey 15-10 FB, the fluidized bed should be fully cleaned to avoid colour contamination and the first production articles should be subjected to cross-cut adhesion per ISO 2409, impact per ISO 6272-2, and salt spray per ISO 9227 before release.
