A cross-linkable functionalised isocyanate composition comprising [1] a functionalised isocyanate product being a reaction product of an isocyanate component having at least two isocyanate groups; and an ethylenically unsaturated component having at least one functional group that is reactive with the isocyanate, and at least one ethylenically unsaturated group, wherein the isocyanate and the ethylenically unsaturated component are such that the functionalised isocyanate has at least three ethylenically unsaturated groups, [2] a monomer comprising a cross-linking monomer having at least two ethylenically unsaturated groups, and [3] a reinforcing component. Also disclosed is a cross-linkable functionalised isocyanate composition comprising [1] a urethane acrylate product being a reaction product of an isocyanate having at least two isocyanate groups; and an acrylate component having at least one functional group that is reactive with the isocyanate, and at least one (meth)acrylate group, wherein the isocyanate and the acrylate component are selected such that the urethane acrylate product has at least three (meth)acrylate groups, [2] a monomer comprising a cross-linking monomer having at least two ethylenically unsaturated groups, and [3] a reinforcing component; the cross-linkable functionalised isocyanate composition without a reinforcing component; a functionalised isocyanate being a reaction product of a trimer of isophorone diisocyanate; and an ethylenically unsaturated component having at least one functional group that is reactive with the isocyanate, and at least two ethylenically unsaturated groups, wherein the ethylenically unsaturated component is in stoichiometric excess with respect to the isocyanate groups of the trimer; and a kit comprising the cross-linkable functionalised isocyanate composition; and a process of forming a composite article comprising the cross-linkable functionalised isocyanate composition. |
