Patent ID: 8569398

Claim:
A curable jettable composition having a viscosity less than 30 cps at a temperature within the range of 15° C.-180° C. comprising: (a) at least one low viscosity reactive resin consisting of one or more oxetane compounds, wherein the low viscosity reactive resin has a molecular weight of not greater than 300 Daltons and a viscosity of less than 30 cps at a temperature within the range of 15° C.-180° C.; (b) 40%-50% by weight of a high viscosity resin epoxy resin component wherein the epoxy resin component is a cycloaliphatic epoxy resin selected from 3,4-epoxycyclohexylmethyl-3,4-epoxycyclohexane carboxylate and bis-(3,4-epoxycyclohexyl)adipate and wherein the high viscosity resin has a functionality of greater than or equal to 2 and a viscosity greater than twice the viscosity of the low viscosity reactive resin at a temperature within the range of 15° C.-180° C.; (c) at least one curable toughener comprising a polymer or oligomer having a hydroxy, or acrylic group; (d) at least one initiator; (e) at least one stabilizer and optionally (f) a vinyl ether curable co-diluent and (g) one or more additives and wherein the low viscosity reactive resin is slower to react than the high viscosity resin.
