Q1: What is the primary application of CRYLCOAT 2670-3 in powder coatings?
A: CRYLCOAT 2670-3 is a carboxyl-functional polyester resin specifically designed for use in TGIC-free, high-gloss, and durable thermosetting powder coatings—particularly for indoor and moderate outdoor applications such as office furniture, shelving, and general metalware.
Q2: Which crosslinkers is CRYLCOAT 2670-3 compatible with?
A: This resin is formulated to react efficiently with standard epoxy-functional crosslinkers, including glycidyl ester types (e.g., Primid XL-552) and other TGIC-free alternatives commonly used in premium architectural and industrial powder systems.
Q3: How does CRYLCOAT 2670-3 contribute to film performance in cured coatings?
A: It delivers excellent flow and leveling, good mechanical resistance (including impact and pencil hardness), and enhanced UV stability compared to standard polyester resins—supporting long-term gloss retention and color consistency under typical indoor service conditions.
Q4: Is CRYLCOAT 2670-3 suitable for low-cure or energy-efficient powder coating processes?
A: Yes—it is engineered for reactivity at standard curing temperatures (typically 180–200 °C/10–15 min), and its formulation supports consistent performance even with slight reductions in time or temperature, making it adaptable to modern energy-conscious production lines.
