CYCAT 655 catalyst is a blocked sulfonic acid catalyst designed for controlled curing of amino resins such as melamine-formaldehyde systems in coating formulations.
CYCAT 655 catalyst remains inactive at ambient conditions and becomes active only at elevated curing temperatures, providing excellent storage stability and extended pot life.

This controlled activation ensures improved processing, better flow and leveling, and reduced risk of premature curing.
