CYCAT 600T

CYCAT 600T is an organic acid catalyst recommended to accelerate the crosslinking reaction of amino resins with polymers containing hydroxyl, carboxyl, or amide functionality.
CYCAT 600T is soluble in aliphatic and aromatic hydrocarbons, esters, ketones, alcohols, glycol ethers and water.
CYCAT 600T 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.

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

The “T” grade is optimized for specific reactivity and flow characteristics, providing improved film smoothness, reduced surface defects, and better processing control.
CYCAT 600T 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.

CYCAT 600T may be used as a replacement for less soluble acid catalysts, such as para-toluene sulfonic acid, in low alcohol-containing formulations.
For formulation of 1K systems, CYCAT 600T should be blocked with an appropriate amine, such as AMP (2-amino-2-methyl-1-propanol).

CYCAT 600T is a strong acid catalyst based on dodecylbenzene sulfonic acid supplied in isopropanol.
Supplied as a free acid, CYCAT 600T is recommended to accelerate the crosslinking reaction of amino resins with polymers containing hydroxyl, carboxyl or carbamate functionality.
