Escat 65

ESCAT 65 is a purified imidazole catalyst absorbed onto a silica carrier. The product is used to accelerate the cure of powder coatings that are responsive to imidazole catalysis. Example powder coating chemistries that can be catalyzed with ESCAT 65 include hybrids such as polyester-epoxy, carboxyl acrylic-epoxy, polyesters cured by GMA-functional acrylics, polyester-TGIC and polyester-PT-910. ESCAT 65 reduces the cure temperature of a particular system and shortens the required bake time at a given cure temperature   when compared to non-catalyzed systems.   In addition, this purified imidazole product may provide less yellowing and improved catalysis when compared to competitive imidazole catalysts on silica.


Recommended usage level of ESCAT 65 is 0.1 – 0.3% on total formula weight.   Each application should be tested to determine the optimum catalyst level to achieve the desired cure time and coating properties.
