Escat 66

ESCAT 66 is an imidazole catalyst absorbed onto a silica carrier. Escat 66 is used to accelerate the cure of powder coatings that are responsive to imidazole catalysis. Examples of powder coating chemistries that can be catalyzed with ESCAT 66 include polyester-epoxy and acrylic-epoxy hybrids, polyesters cured with Glycidyl-functional acrylics, polyester-TGIC and polyester-Glycidylester. ESCAT 66 reduces the cure temperature of a 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 exhibit less yellowing and improved catalysis when compared to competitive imidazole catalysts on silica.


Recommended usage level of ESCAT 66 is 0.2 – 0.6% on total formula weight.   Each application should be tested to determine the optimum catalyst level to achieve the desired cure profile and coating properties.
