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.

The present invention relates to anaerobically curable compositions, methods of preparation and methods of use that provide enhanced physical properties when cured in contact with untreated inactive surfaces. The compositions which include isobornyl acrylate, isobornyl methacrylate or combinations thereof in combination with a multi(meth)acrylate and a free-radical initiator, may be used without the addition of a transition metal catalyst.

Optical structures and sheeting that include polyurea and method for forming same are proposed in accordance with aspects of the present invention. One and two-component layers can be used to form the optical structures. The optical structures can include microstructures formed from polyurea. The sheeting can include at least one of cube-corner prisms, open-faced cube-corner prisms, linear prisms, lenticular lenses, moth-eye structures, lenses, Fresnel lens arrays, lenses, and fish-eye lens arrays.

The present invention provides anaerobic adhesive compositions, reaction products of which demonstrate controlled-strength at ambient temperature conditions and enhanced resistance to thermal degradation at elevated temperature conditions. The compositions are (meth)acrylate- and/or polyorganosiloxane-based and may include one or more of a variety of other components, such as certain coreactants, a maleimide component, a diluent component reactive at elevated temperature conditions, mono- or poly-hydroxyalkane components, and other components.
