CYCAT 4107 is a latent acid catalyst designed for use in thermosetting resin systems, particularly in amino resin-based coatings and industrial formulations.
CYCAT 4107 remains chemically inactive at room temperature, allowing extended storage stability and processing time, but becomes active upon heating by releasing acid species that initiate crosslinking reactions.

This controlled activation mechanism makes CYCAT 4107 highly suitable for applications requiring precise curing conditions, such as automotive coatings, metal finishes, and high-performance industrial paints.
By enabling uniform network formation within the polymer matrix, CYCAT 4107 improves final film properties including hardness, chemical resistance, adhesion, and durability.

CYCAT 4107 is especially valued in formulations where premature curing must be avoided, as it ensures better pot life and formulation stability while still delivering efficient curing under elevated temperatures.

CYCAT 4107 is an amine-blocked p-toluenesulfonic acid in isopropanol.
CYCAT 4107 is recommended for applications where a wrinkled or textured finish is desired with thermoset coatings crosslinked with highly alkylated amino resins, like CYMEL® 303 LF.
