Electrostatic Spray PE Powder Coating High Adhesion for Metal Components
Electrostatic Spray PE Powder Coating high adhesion for Metal ComponentsProduct Introduction
PECOAT® Low-Temperature Resistant Electrostatic Spray Thermoplastic PE Powder Coating is engineered to protect metal surfaces in harsh environments, combining cold resistance, corrosion resistance, and ease of use. Made from high-quality polyethylene resin and tailored additives, it delivers no cracking at -35℃ for 60h (per Q/HJ 008-2008) and 500h of salt spray resistance (no blistering, peeling, or rusting per GB/T 18226)—critical for outdoor, cold-climate, or coastal applications. It supports electrostatic spray and works with cold/preheated workpieces, making it suitable for industries like marine, refrigeration, and industrial infrastructure, where durability against temperature fluctuations and moisture is essential.
Core Advantages
• Exceptional Low-Temperature Performance: Maintains structural integrity in frigid conditions, ideal for refrigeration equipment, outdoor metal structures, and cold-storage pipelines.
• Superior Corrosion Resistance: Withstands salt spray, humidity, and chemicals (5% HCl/NaOH), protecting metal components from rust and degradation.
• User-Friendly Application: No strict pre-heating requirements (works on cold parts) and simple electrostatic spray operation, reducing production time and labor costs.
• Customizable Finish: Gloss levels (10-75 at 60°) adjust to customer needs, ensuring both functionality and aesthetic appeal for visible components.

Target Applications
• Outdoor Metal Structures: Guardrails, lamp posts, and building facades (resists rain, snow, and salt air).
• Refrigeration Systems: Pipes and shelves in cold storage (withstands -35℃ without cracking).
• Marine Equipment: Metal parts of boats and docks (500h salt spray resistance prevents rust).
• Chemical Pipelines: Transport lines for acidic/alkaline fluids (chemical resistance avoids coating damage).
Usage & Safety
• Electrostatic Deposition (Pre-Heated): Preheat parts to 205℃, apply 203-300μm thickness; short post-heating improves finish (adjust time/temp for part size).
• Safety: Operators must wear dust masks and goggles to avoid inhalation; minimize skin contact with powder.
