  • Publication number: 20050239952
    Abstract: A curable composition having enhanced cure speed which includes a curable component, a cure system and an additive for enhancing cure speed. The additive includes an alkali metal halide salt and the reaction product of: (a) a polyfunctional isocyanate and a member selected from the group consisting of an hydroxy and an amine; or (b) a phosgene or phosgene derivative, and a compound having 3 to 7 polyethylene glycol ether units terminated at one end with an ether group and at the other end with a reactive functional group selected from the group consisting of an amine, an amide, a thiol and an alcohol; or (c) a monohydroxy compound, a diisocyanate and a polyamine. Alternatively, in place of or in combination with the cure speed enhancing additive, an aromatic substituted (meth)acryl functionalized component may be incorporated into the curable component to achieve enhanced cure speed.
