Q1: What is the primary application of CRYLCOAT 2698-3 in powder coating systems?
A: CRYLCOAT 2698-3 is a carboxyl-functional polyester resin specifically designed for use in TGIC-free, high-gloss, decorative powder coatings—particularly where excellent flow, leveling, and long-term weather resistance are required, such as for architectural aluminum extrusions and outdoor metal furniture.
Q2: Is CRYLCOAT 2698-3 compatible with common curing agents used in TGIC-free systems?
A: Yes—it is fully compatible with standard TGIC-free crosslinkers such as hydroxyalkyl amide (HAA) types, delivering robust cure response and good storage stability when formulated according to Allnex’s recommended guidelines.
Q3: How does CRYLCOAT 2698-3 perform under UV exposure and humid conditions?
A: This resin delivers enhanced UV stability and resistance to chalking and gloss loss, making it suitable for exterior applications. Its molecular design supports good retention of color and mechanical properties after prolonged exposure to sunlight and cyclic humidity.
Q4: What are key handling and storage recommendations for this resin?
A: Store in a cool, dry place away from direct sunlight and sources of heat or ignition. Keep containers tightly sealed to prevent moisture absorption. For optimal performance, process within the recommended shelf life and avoid prolonged exposure to ambient humidity during handling.
