Electrostatic Spray Thermoplastic PE Powder Coating – Thin-Coat Solution for Metal
Product Overview
PECOAT® Electrostatic Spray Thermoplastic PE Powder Coating is a high-performance thermoplastic powder formulated from polyethylene resin, compatibilizers, functional additives, pigments, and fillers. Designed for versatility and reliability, it stands out with excellent adhesion, anti-corrosive properties, chemical stability, electrical insulation, and low-temperature resistance—making it a top choice for industrial protection. Unlike ordinary PE powder coatings, it features a thin coating design and works seamlessly with both cold and preheated workpieces. It also supports multiple application methods, including electrostatic spray, fluidized bed dip, and block spraying, catering to diverse production needs across sectors like chemical processing, metal manufacturing, and pipeline maintenance.
Key Characteristics
• Multi-Application Flexibility: Compatible with electrostatic spray (for precise coverage), fluidized bed dip (for uniform coating on complex shapes), and block spraying (for large-scale parts), adapting to different workpiece types.
• Broad Workpiece Compatibility: Functions effectively on both cold workpieces and preheated workpieces, eliminating strict pre-treatment constraints and simplifying workflow.
• Thin Coating & Fine Particle Size: The thin coating reduces material usage while maintaining protection, and its particle size is optimized for both electrostatic spraying and fluidized bed processes.
• Durable Protection: Resists corrosion, low temperatures (-35℃ for 60h with no cracks), and harsh chemicals (5% HCl for 400h, 5% NaOH for 72h with no coating changes), ensuring long-lasting performance.

Application & Usage
Ideal for chemical equipment (reactors, tanks), industrial pipelines, and metal components—especially complex workpieces where uniform coating is challenging. Its application methods include:
• Fluidized Bed: Preheat parts to 230℃ (adjust for thickness), dip for 8-10 seconds, let excess powder stand 1 minute (blow off), then post-heat at 193-205℃ for 3-4 minutes.
• Electrostatic Deposition (No Pre-Heat): Apply 203-254μm thickness, use 40-60kV for Corona equipment, post-heat at 175-220℃ for 5-10 minutes (based on metal thickness).
Storage & Safety
• Packing/Storage: 25kg/bag; store in clean, dry area
• Health & Safety: Non-toxic, but avoid dust inhalation (wear masks/goggles) and prolonged skin contact.
