Highly crosslinkable solid saturated polyester with excellent compatibility in thermosetting powder coating systems.
Outstanding gloss retention and weather resistance due to fully saturated backbone and low aromatic content.
Optimized melt viscosity for smooth film formation and excellent flow/leveling in curing cycles.
Low volatile organic content (VOC-free), supporting sustainable powder coating formulations.
Consistent batch-to-batch reproducibility and high thermal stability during extrusion and curing.
Exterior architectural powder coatings for aluminum façades and curtain walls.
Automotive non-structural components such as trim, brackets, and under-hood parts.
General industrial metal finishing for appliances, furniture, and office equipment.
Functional coatings requiring long-term UV stability and corrosion protection.
Hybrid epoxy-polyester powder coatings for enhanced chemical resistance and mechanical performance.
