CYCAT 655 catalyst is a strong acid catalyst based on dinonylnaphthalene disulfonic acid supplied in isobutanol. It is recommended to accelerate the cure between hydroxyl, carboxyl, and amide functional groups with alkylated amino crosslinking agents. CYCAT 655 is recommended for use in electrocoating applications to achieve cure in the range of 110 - 135°C in 15 - 30 minutes, or to reduce the baking time at higher baking temperatures. CYCAT 655 is also recommended for coatings applied by other application techniques, providing improved adhesion and resistance properties compared with other sulfonic acid catalysts. Since CYCAT 655 is a free acid, package stability could be adversely impacted.
