摘要： A method for shielding a metal substrate surface during the application of heat to the surroundings of the substrate which comprises. A liquid maskant composition is formed which comprises: a) at least one of a polycarbonate urethane diacrylate oligomer, a polycarbonate urethane dimethacrylate oligomer, a polycarbonate caprolactone urethane diacrylate oligomer, or a polycarbonate caprolactone urethane dimethacrylate oligomer; b) a reactive diluent capable of free radical polymerization; and c) a photoinitiator capable of generating free radicals when exposed to actinic radiation. The maskant composition is applied onto a surface of the substrate. The maskant composition is then exposed to sufficient actinic radiation to polymerize or crosslink the composition into a dried maskant. In use the dried maskant is heated on the substrate to a temperature of from about 400° F. to about 600° F. for from about 20 minutes to about 30 minutes, and then the maskant is removed.

摘要： Urethane acrylate oligomers, suitable for use in coatings and like formulations, prepared by capping polyols having hydroxyl functionality (fOH) equal to or greater than 4, using 2-isocyanatoethyl acrylate or 2-isocyanatoethyl methacrylate, thereby avoiding the gelation that normally occurs in attempting to prepare urethane acrylates with high/OH polyols by reaction with diisocyanates. Reaction of low molecular weight polyols, containing two or three hydroxyl groups, with mono isocyanate(meth)acrylate monomers produces useful, low viscosity urethane (meth)acrylate oligomers. Specifically, capping of a mole of 2,2-dihydroxymethyl butanoic acid by two moles of 2-isocyanatoethyl acrylate molecules leads to the formation of radiation curable water-soluble liquid monomers that are transparent and soluble in water. Oligomers obtained by capping with 2-isocyanatoethyl acrylate demonstrate enhanced adhesion to glass and stainless steel. Solid, hydroxyl-containing chemicals can be transformed to liquids by reaction with monoisocyanate-(meth)acrylate monomers
