General：

 

IRGACURE 2022 is a highly efficient liquid curing agent that is usedto initiate radical polymerization of unsaturated resins after UV
light exposure.

 

IRGACURE 2022 is the first choice for use in pigmentedformulations of all colors, for curing of thick sections or for UVstabilized
clear coatings. Unsaturated resins that are particularlysuited are those based on a prepolymer – e.g., acrylates or unsaturated polyesters – in combination with mono- or  multifunctional monomers as reactive diluents.

 

 

IRGACURE 2022 is to be considered as a one to one replacement for IRGACURE 2020. Compared to IRGACURE 2020 this new blend shows significantly improved long-term storage stability.
