CYCAT 500

CYCAT 500 is a strong acid catalyst based on dinonylnaphthalene disulfonic acid supplied in isobutanol.
CYCAT 500 is widely used in industrial coatings, including automotive finishes, coil coatings, and can coatings, where it enhances crosslinking efficiency, chemical resistance, hardness, and overall durability of the final coating.
CYCAT 500 is used in electrocoating applications to achieve cure in the range of 110-135°C in 15-30 minutes, or to reduce the baking time at higher baking temperatures.

CYCAT 500 is a catalyst used in electrostatic spraying applications, particularly in coil coating, e-coat & electrodeposition, primers, and solventless or high solids coatings.
CYCAT 500 features good cure acceleration, high electrical resistance, improved adhesion, and low energy consumption.
CYCAT 500 functions as a catalyst in CASE ingredients.

CYCAT 500 is a blocked acid catalyst based on sulfonic acid chemistry, designed to provide controlled curing of amino resins such as melamine-formaldehyde systems in coating formulations.
Unlike free acid catalysts, CYCAT 500 remains inactive at room temperature and becomes active only at elevated curing temperatures, offering excellent storage stability and extended pot life.

This delayed activation allows better processing control and improved film appearance, reducing risks of premature gelation.
