Testing method for testing products with a coating cured by radiation determines the coating's cross-linking status in a non-destructive manner

摘要

A reaction product i.e. polymer (5) in basic UV coating powder is produced, in which first (3) and second (4) reactive double bonds in a binding agent i.e. a prepolymer in a basic UV coating powder have been changed into a C-C bond, i.e. a carbon single bond.
