Vestosint® Polyamide 12 Coating Service
Durable. Versatile. Corrosion-Resistant.
Our Vestosint® Polyamide 12 (PA12) coating service provides a tough, smooth, and highly durable finish through Evonik-certified fluidized bed and electrostatic coating techniques. Using Vestosint® 1111 Fine Powders, a high-performance thermoplastic developed by Evonik, we deliver coatings that offer excellent adhesion, flexibility, and resistance to corrosion, abrasion, and impact — even in aggressive industrial or marine environments.
Vestosint® coatings are engineered for outstanding mechanical strength and environmental stability, making them ideal for metal protection and functional finishing.
Key performance benefits include:
Exceptional corrosion resistance – effective against salt water, fuels, and a wide range of chemicals.
Superior abrasion and impact strength – minimal wear under high mechanical stress (Taber CS17 < 1 mg / 100 turns).
Excellent weatherability – stable gloss and adhesion even after long-term UV and outdoor exposure.
Low water absorption – maintains performance in humid or submerged conditions (≤ 1.9%).
High dielectric strength – up to 90 kV/mm, ideal for electrical insulation.
Non-toxic and compliant – meets modern environmental and safety standards (RoHS, REACH).
Smooth, aesthetic finish – available in various colors and gloss levels.
Vestosint® Polyamide 12 coatings are ideal for:
Industrial piping, valves, and fittings
Marine and offshore metal structures
Automotive and mechanical parts
Food and potable water contact equipment
Wire baskets, racks, and architectural components
Electrical and electronic housings
Our coating procedures comply with Evonik’s official Vestosint® Coating Standards, ensuring excellent coverage, adhesion, and surface finish.
Grit blasting to SA 2.5/3 (ISO 8501-01) using angular steel grit or corundum.
Achieved roughness: Rz 35–45 µm.
Coating applied within 8 hours of surface prep to prevent oxidation.
Preheated components are immersed in a fluidized bed of Vestosint® 1111 powder, ensuring uniform coating build-up.
Typical coating thickness: 200–500 µm, depending on part geometry and service requirements.
Optimized for steel, aluminum, and galvanized substrates.
Electrostatic charge range: ±35–45 kV, current 10–30 µA.
Fusion at 190–210°C, ensuring full coalescence and excellent bonding.
Controlled cooling to preserve mechanical integrity and smooth surface finish.
