The present invention includes silicon-containing (meth)acrylate compounds of formula (I): where A is a C-Corganic moiety such as an alkyl or aryl moiety, B is a silane functional group, C is a (meth)acrylate functional group and D is an allyl functional group, with w=0 or 1, z=0, 1 or 2, x=1, 2 or 3, y=1, 2 or 3 and w+x+y+z=4. The compounds are suitable for use in curable compositions, such as peroxide-curable compositions or radiation-curable compositions and may be applied to a substrate as a coating or sealant, for example. Compositions containing the silicon-containing (meth)acrylate compounds may have reduced volatility and odor problems along with improved adhesion to substrates, increased crosslink density and/or improved hardness.

Silicon-containing (meth) acrylate compounds

A composition comprising one or more radiation curable monomers and/or oligomers and one or heat stable composition comprising at least one radiation-curable alpha, beta-ethylenically unsaturated compound, at least one phenolic stabilizer, and at least one non-phenolic stabilizer selected from the group consisting of hydroperoxide decomposers and free radical traps. The compositions and methods are useful in applications such as radiation curable ink jet systems where viscosity is reduced by heating.

High temperature stabilization of UV systems

Compositions comprising acid salts of amine-functionalized styrene-maleic anhydride resins are disclosed. The salts can be dissolved in organic solvents, UV/EB polymerizable monomers and/or oligomers, and/or water and act as a polymeric surfactants to disperse pigments or fillers, emulsifying agents, or hard resin additives in a variety of formulations. The compositions react under UV/EB cure conditions, and provide enhanced properties such as cure speed, hardness and adhesion to polymer compositions.
