Abstract:
1. A method for evaluating a UV polymerizable cationic system for coating performance on a substrate, comprising: a) selecting a UV polymerizable cationic system to investigate for coating performance; b) identifying or selecting core and mesh variables for the selected UV polymerizable cationic coating system; c) estimating a coating cure for the selected UV polymerizable cationic coating system in spatial dimensions of depth and width by numerical solution of a Polychromatic Governing Set of Equations based on the identified core and mesh variables; and d) evaluating the selected coating system based on the obtained estimated cure depth and width; wherein the Polychromatic Governing Set of Equations calculates a concentration of cationic active centers produced during a UV illumination period and in addition, a diffusion of the cationic active centers in the two spatial dimensions during a specified period of time following termination of the illumination is calculated according to equation (5): wherein C and D
