Abstract: A curable resin composition comprising: (1) a urethane (meth)acrylate; (2) a reactive diluent selected from the group consisting of i) a hydroxyl alkyl (meth)acrylate monomer where the acrylate group, which is attached to the carbonyl group, is attached to a hydrogen or a methyl group and the carbonyl group is attached to the hydroxyl group thru an R2 alkylene group containing 2 to 18 carbon atoms per molecule.

Abstract: Embodiments of the present disclosure are directed to polyether-acetal polyol compositions, more particularly to polyol compositions including a polyether-acetal polyol that can be utilized to form polyurethanes. As an example, a polyurethane formulation can include a polyol composition including a polyether-acetal polyol functionalized with at least one acetal functional group, where the polyol composition has an average hydroxyl functionality from 2 to 8 and a hydroxyl equivalent weight from 150 to 4000, where the portion of the polyether-acetal polyol that is functionalized with the at least one acetal functional group is 1 percent to 40 percent of a total weight of the polyether-acetal polyol, where the polyether-acetal polyol has a primary hydroxyl group content of at least 55 percent, and a polyisocyanate, where the polyurethane formulation has an isocyanate index in a range from 70 to 500.

Abstract: A curable composition includes (A) a first component having from 5.0 wt % to 39.0 wt %, based on the total weight of the first component, of a toughening agent component including a Bisphenol F based epoxy resin and an urethane acrylate component, a hardener component having at least one amine based hardener and is present in a ratio of 0.8 to 1.2, based on a number of equivalents of amino hydrogen groups in the hardener component to a number of equivalents of reactive groups in the first component capable of forming a covalent link with the amine reactive groups in the hardener, and an epoxy base component that accounts for a remainder of the total weight of the first component and that has at least one epoxy resin separately provided from the Bisphenol F based epoxy resin. The Bisphenol F based epoxy resin is present in an amount from 2.5 wt % to 50.0 wt % and the urethane acrylate component is present in an amount from 50.0 wt % to 97.5 wt %, based on the total weight of the toughening agent component. The urethane acrylate component includes the capping reaction product of an acrylate and an isocyanate terminated prepolymer and the isocyanate-terminated prepolymer is the reaction product of a polyisocyanate and at least a DMC derived polyol having a molecular weight of at least 3000 g/mol. The curable composition may further include (B) an optional second component that has at least one of a filler and any additional ingredient for a targeted application of the curable composition.
