Models and Options
Custom color matching available for any RAL or Pantone code. Gloss levels can be adjusted within 5%-95%. Additionally, specific functional coatings such as antibacterial or food-grade are available upon request.
Materials and Structure
The coating is formulated with polyester resin, TGIC curing agent, pigments, and additives. This composition provides a dense, cross-linked film after curing, delivering excellent mechanical properties and chemical resistance.
Applications
Architectural: aluminum doors/windows, curtain walls, railings, outdoor furniture, highway guardrails, street light poles
Home Appliances: casings for refrigerators, washing machines, air conditioners, microwave ovens
Custom colors (RAL/Pantone), gloss levels, and packaging options available. Minimum order quantity for sample is 1 kg; bulk orders from 100 kg or 300 kg. We support customer-specific color matching and special performance requirements.
Case Study
Industrial Shelving in Colombia: A major industrial shelving manufacturer used our customized RAL 5002 blue coating for 100 tons of storage racks. The coating's impact resistance (more than 3 times traditional liquid paint) and salt spray performance ensured long-term durability in humid warehouse environments. The project highlighted the system's zero VOC emissions, aligning with the client's green manufacturing goals.
