Features Of Toyobo GA-1310 Crystalline Polyester Resin

  1. Highly crystalline structure enabling rapid melt crystallization and excellent storage stability in powder form.

  2. Optimized for low-melt extrusion and high-resolution powder coating applications with narrow particle size distribution.

  3. Excellent flowability and electrostatic charging characteristics for uniform film formation and edge coverage.

  4. Superior chemical resistance and mechanical durability in cured coatings, especially against UV exposure and humidity.

  5. Designed for compatibility with standard TGIC-free curing agents, supporting sustainable, low-VOC coating systems.

Typical Applications Of Toyobo GA-1310 Crystalline Polyester Resin

  1. Architectural metal cladding and curtain wall coatings requiring long-term color retention and weather resistance.

  2. Appliance coatings for refrigerators, washing machines, and ovens demanding smooth finish and thermal stability.

  3. Outdoor furniture and garden equipment coatings exposed to cyclic temperature and moisture variations.

  4. Automotive non-critical exterior trim parts where gloss consistency and chip resistance are essential.

  5. General industrial metal finishing for HVAC components, lighting fixtures, and office furniture.
