Abstract: A method for making a one package heat curable (i.e. thermosetting) composition which, on heating, forms a urethane/epoxy/silicone interpenetrating polymer network (IPN) system; one package heat curable compositions made by such a method; metal reinforcing patches, directly adherent to an oily metal surface such as an oily steel surface, comprising a sheet-like carrier having thereon such a one package heat curable composition in combination with a filler admixed therewith, said filler possibly including magnetic particles; a method for reinforcing metal which comprises applying thereto such a metal reinforcing patch and curing said heat curable composition at an elevated temperature to form a urethane/epoxy/silicone interpenetrating polymer network.

Abstract: What are disclosed are a one pot moisture-curable two-component coating composition comprising a first component having at least one isocyanate group and at least one hydrolyzable alkoxysilane group therein and a second component having at least one oxazolidine group therein, methods of forming a tenacious coating therewith on non-porous substrates such as glass and of further applying a resinous sealant composition over such a tenacious coating used as a primer, and coated substrates having such a tenacious coating thereon without or with a further resinous sealant composition.
