The working principle of delayed amine catalyst C225

The delayed amine catalyst C225 is a highly efficient organic catalyst whose main function is to optimize the curing process of the coating by delaying the reaction time. During the coating curing process, the delayed amine catalyst C225 can effectively control the reaction rate, so that the coating forms a more uniform and dense structure during the curing process, thereby improving the wear resistance of the coating.
