High Purity ETFE Electrostatic Spray Coating Powder CAS 25067-11-2 for

The SHEC-ES100 ETFE Electrostatic Spray Coating Powder is a premium-grade ethylene tetrafluoroethylene copolymer specifically formulated for electrostatic spray application onto metal substrates. With CAS registry number 25067-11-2, this high-purity fluoropolymer powder delivers outstanding corrosion protection, chemical inertness, and long-term thermal stability for demanding industrial coating environments. The material is manufactured under stringent quality control protocols conforming to ASTM D3159 specifications, ensuring consistent particle size distribution, melt flow characteristics, and coating performance across every batch.

Engineered for electrostatic deposition, SHEC-ES100 features optimized particle morphology and controlled triboelectric charging properties that enable uniform powder pickup, efficient transfer efficiency, and smooth film formation on complex geometries including pipe interiors, valve bodies, impellers, and reactor vessels. The resulting coating exhibits a dense, non-porous barrier that resists permeation by aggressive chemicals including concentrated mineral acids, alkalis, organic solvents, and oxidizing agents even at elevated temperatures. This makes it an ideal choice for chemical processing plants, semiconductor fabrication facilities, pharmaceutical manufacturing equipment, and offshore oil and gas infrastructure where coating failure is not an option.

• Electrostatic Spray Optimized: Specially engineered particle size distribution (D50: 30-50 μm) and surface treatment for maximum first-pass transfer efficiency in corona and tribo electrostatic spray systems, reducing powder waste and improving coating consistency on complex-shaped workpieces.
• Exceptional Chemical Resistance: The fully fluorinated copolymer backbone provides near-universal resistance to mineral acids, strong bases, chlorinated solvents, ketones, esters, and oxidizing media, maintaining coating integrity in chemical processing environments where conventional epoxies and polyesters rapidly degrade.
• Broad Thermal Operating Range: With a melting point of 220-270°C and continuous service temperature capability from -200°C to +150°C, the coating withstands thermal cycling, steam sterilization, and high-temperature process conditions without embrittlement, delamination, or loss of protective properties.
• High Purity Formulation: Volatile matter content limited to ≤0.1% ensures minimal outgassing during melt processing and cure, producing bubble-free, dense coatings with excellent substrate adhesion and no pinhole defects that could compromise barrier performance in critical applications.
• Superior Mechanical Durability: Tensile strength exceeding 40 MPa combined with breaking elongation above 320% provides a tough yet flexible coating that resists impact damage, thermal expansion stress cracking, and abrasion from particulate-laden fluid flow in pumps, pipes, and agitated vessels.
• Excellent Dielectric Properties: Low dielectric dissipation factor (≤0.009 at 10^6 Hz) makes this coating suitable for electrical insulation applications where both corrosion protection and electrical isolation are required, such as busbar coatings and transformer component protection.
• Smooth Non-Stick Surface: The inherent low surface energy of ETFE produces a smooth, easy-to-clean coating surface that minimizes product adhesion, reduces fouling in process equipment, and facilitates rapid CIP (clean-in-place) operations in food, pharmaceutical, and fine chemical production lines.

The SHEC-ES100 ETFE electrostatic spray coating powder is widely utilized across industries requiring high-performance corrosion protection combined with excellent release properties. In chemical processing plants, it serves as the primary protective lining for reactor vessels, storage tanks, heat exchanger tubesheets, and centrifugal pump casings exposed to aggressive acid and solvent mixtures. Semiconductor equipment manufacturers apply this coating to wet bench components, chemical delivery systems, and exhaust ductwork where ultra-high purity and resistance to HF, HNO₃, and H₂SO₄ mixtures are essential. In the pharmaceutical sector, ETFE-coated vessels and piping prevent product contamination while withstanding rigorous CIP and SIP sterilization protocols involving steam, caustic solutions, and oxidizing sanitizers.

Beyond chemical processing, the coating finds application in food processing equipment including mixing paddles, conveyor components, and filling machine parts where FDA-compliant non-stick surfaces minimize product waste and cleaning downtime. Water treatment facilities use ETFE coatings on valve bodies, weirs, and flocculator components to prevent corrosion from chlorinated water and treatment chemicals. In the oil and gas industry, downhole tool components, subsea valve actuators, and offshore platform structural elements benefit from the combined corrosion and mechanical protection. Power generation plants apply this coating to flue gas desulfurization equipment components, cooling water system piping, and electrostatic precipitator internals operating in highly corrosive, high-humidity environments.

Each order of SHEC-ES100 ETFE electrostatic spray coating powder is packaged in 25 KG multi-layer bags consisting of an inner PE liner for moisture protection and an outer woven polypropylene bag for mechanical durability during transport and storage. Custom packaging options including 500 KG supersacks and 10 KG trial packs are available upon request. Every production lot undergoes comprehensive quality testing including melt flow rate analysis, particle size distribution measurement, thermal analysis via DSC, and coating trial evaluation on standardized test coupons.
