    摘要： A two package UV curable conformal coating has been developed which possesses low moisture permeability and good electrical properties and provides a cure for shadowing of components on a printed wiring board. The conformal coating is a mixture of Component (A) which is a mixture of (1) from about 40 to 80% by weight, of a urethane having a free isocyanate group; (2) from about 20 to 60%, by weight, of reactive acrylate diluents; (3) from 0 to about 10% by weight of UV photoinitiators; and (4) from 0 to about 10% by weight of additives; and component (B) which is a mixture of (1) about 50 to 80% by weight of an acrylate-epoxy resin; (2) about 1 to 10% by weight of an acrylate-urethane oligomer; (3) about 10 to 94% by weight of reactive acrylate monomers; (4) from 0 to about 10%, by weight, of UV photoinitiators; and (5) from 0 to about 10% by weight of additives; with the proviso that the total weight percentage of said photoinitiators and additives not be less than 1 percent and not exceed about 10 percent. Components A and B may be mixed in equal parts, by weight, or in a 1 to 2 part ratio, by weight.

    摘要： Disclosed is a resin composition which comprises a mixture of a polyester, an acrylate urethane, in about stoichiometric proportion with the polyester up to about 10% excess polyester over stoichiometric, and a liquid acrylate reactive diluent sufficient to give the resin composition the viscosity of less than 5,000 centipoise. The polyester resin is the reaction product of a polyhydroxy compound having at least three hydroxyl groups, and an aromatic compound that is at least difunctional in acid, anhydride, or ester groups, where the proportion of the polyhydroxy compound to the aromatic compound is such that the polyester has about 150 to about 250 mole % excess hydroxyl groups. The acrylate urethane compound is the reaction product of a hydroxy acrylate and an isocyanate having at least two isocyanate groups, where the hydroxy acrylate and a hydroxy acrylate having a single hydroxyl group are equimolar (when a diisocyanate is used) with the isocyanate .+-.10 mole %. Also disclosed is a method of making the resin composition.
