Method & Evidence

AimCan a hybrid UV and thermal initiation system for epoxy (meth)acrylate coatings improve cure uniformity and reduce defects on complex surfaces compared to UV-only curing?
MethodExperimental
ProcedureEpoxy (meth)acrylate resins were synthesized by reacting epoxy resins with acrylic or methacrylic acid. These resins were then formulated into coating compositions. The curing behavior and properties of the coatings were investigated using a combination of UV radiation and thermal initiation, and compared to UV-only cured coatings.
