CYCAT 600A

CYCAT 600A is soluble in aliphatic and aromatic hydrocarbons, esters, ketones, alcohols, glycol ethers and water.
CYCAT 600A is recommended to accelerate the crosslinking reaction of amino resins with polymers containing hydroxyl, carboxyl, or amide functionality.
CYCAT 600A may be used as a replacement for less soluble acid catalysts, such as para-toluene sulfonic acid, in low alcohol-containing formulations.

CYCAT 600A is a blocked sulfonic acid catalyst developed for controlled curing of amino resins such as melamine-formaldehyde systems in coating formulations.
CYCAT 600A remains inactive at ambient conditions and becomes active only at elevated curing temperatures, providing excellent storage stability and extended pot life.

Compared to standard blocked catalysts, CYCAT 600A offers optimized reactivity balance, enabling smooth film formation, improved flow, and reduced risk of premature curing.
CYCAT 600A is widely used in automotive, industrial, coil, and can coatings, where it enhances crosslinking efficiency, resulting in coatings with high hardness, chemical resistance, and long-term durability.
