Specialty Formulated Sulfonic Acid Catalysts

The DYNACAT® lines of catalyst were specifically formulated for accelerating the cure of Amino Crosslinking agents. Each catalyst is designed to fulfill a specific application requirement, depending on the formula composition and curing conditions.  While the acid catalysts provide the fastest cure and lower curing temperature, blocked catalysts are typically chosen for systems requiring greater package stability
