Compositions useful as UV curable conformal coatings are mixtures, substantially free of isocyanate condensation catalyst, of the following constituents:

Conformal coating systems

An anaerobic adhesive composition activatable by ultraviolet or visible radiation is disclosed which forms strong bonds with lapped surfaces and which is comprised of (a) an anaerobically polymerizable acrylate ester monomer, (b) a compound which decomposes upon exposure to ultraviolet or visible light radiation to release a strong acid, (c) a peroxy free radical initiator capable of initiating the polymerization of the monomer upon substantial exclusion of oxygen and (d) an activator of anaerobic polymerization which, in the presence of a strong acid, reacts with the peroxide initiator to produce free radicals to catalyze the anaerobic polymerization of the monomer.

Radiation-activatable anaerobic adhesive composition

An improved dental filling material is prepared from polymerizable urethane-acrylate resins which cure by a free-radical mechanism to form hard and durable filling compositions which bond strongly and adhesively to tooth enamel, to dentin, to dental prostheses and to preexisting dental filling materials.
