Catacure KC
Blocked curing catalyst for fully alkylated melamine baking paints, enables lower baking temperatures or shorter baking times
Catacure KC is a blocked curing catalyst used in baking paints especially for fully alkylated melamines which need strong catalyst. It can either lower baking temperature or shorten baking time.
Key properties
- In general, baking paint based on fully alkylated melamine formaldehyde resin, needs higher baking temperature to ensure fully cross-linking. If lower temperature is expected or limited, a strong acid catalyst is required to promote reactions. Catacure KC is an additive used for this purpose.
- When added in baking paint, Catacure KC, compared to unblocked P-TSA, shows better storage stability, lower viscosity, less gelation tendency.
- Catacure KC exhibits lower deblocking temperature(130 - 150 °C), i.e., lower baking temperature compared to other amine salts of P-TSA.
- Catacure KC shows better over-baking yellowing resistance than other amine salt.
