Unlike typical free radical curing adhesives & sealants, cationic UV epoxy adhesives can be formulated to cure between opaque substrates. The delay UV cure epoxy (sometimes referred to as dark cure) still requires light to activate the adhesive but due to the unique polymerization mechanism of highly innovative and engineered epoxy cationic systems, the cure will complete in absence of additional light. What is a Free Radical Adhesive? Typical UV…
