CYCAT® 500 catalyst

Technical Datasheet | Supplied by allnex
CYCAT® 500 catalyst is dinonylnaphthalene disulfonic acid- based strong acid catalyst by allnex. It accelerates the cure between hydroxyl, carboxyl and amide functional groups with alkylated amino crosslinking agents. Used in electrocoating applications to achieve cure at 110-135°C in 15-30 minutes, or to reduce the baking time at higher baking temperatures. Exhibits high electrical resistivity and reduces energy requirements. Designed for primers, coil coating finishes, high solids systems and electrostatic spray systems. It has a shelf life of 1080 days. Recommended dosage level of CYCAT® 500 catalyst is 1-3%.
