The invention is a radiation curable coating composition containing epoxyacrylate formed by ring opening reaction between (meth)acrylic acid and a self-dispersing epoxy resin in an aqueous system.

Radiation curable compositions

Ring opening products of epoxides with fatty acid methyl esters with alkanols or water are eminently suitable as viscosity adjusters (reducers) for high-viscosity polyols.

Viscosity reducer for highly viscous polyols

Fatty acid esters of which the fatty acid constituents are fatty acids containing a total of 12 to 22 carbon atoms and of which the alcohol constituents are saturated and/or mono- or polyolefinically unsaturated monoalcohols containing a total of 1 to 22 carbon atoms, with the additional proviso that the fatty acid constituents of the esters contain saturated and/or mono- or polyolefinically unsaturated fatty acids and have a branched structure, isostearic acid being excluded as the fatty acid constituent of the esters, are suitable as solvents for printing inks.

Fatty acid esters based on branched fatty acids and their use as printing ink solvents

Fatty (meth)acrylates having a %-EpO content of below 0.6, which are reaction products of epoxidized compounds selected from the group consisting of epoxidized fatty acid esters, epoxidized triglycerides and mixtures thereof, and acids selected from the group consisting of acrylic acid, methacrylic acid and mixtures thereof, wherein the %-EpO content of the epoxidized compound is above 6.4, wherein the epoxidized compound is an epoxidation product of fatty acid moieties having one or more carbon-carbon double bonds, wherein less than 20 mole % of the fatty acid moieties contain three or more carbon-carbon double bonds, and wherein greater than 60 mole % of the fatty acid moieties contain two carbon-carbon double bonds are useful as pigment dispersants. Pigment dispersant concentrates, aqueous pigment dispersions and methods of dispersing pigments with the fatty (meth)acrylates are described.

Water-based coating composition comprising: (a) from 0.5 to 90% by weight of at least one epoxy resin other than self-dispersing epoxy resins; (b) from 0.5 to 90% by weight of at least one (meth)acrylate of a polyol; (c) from 5.0 to 98.0% by weight of water; and (d) from 0.5 to 10% by weight of one or more dispersants; wherein the at least one (meth)acrylate comprises at least two (meth)acrylate groups per molecule, and wherein the Brookfield viscosity of the composition is less than 15000 mPas.

Water-based coating compositions containing epoxy resin(s) and (meth)acrylate(s), and methods of using the same

Water-based coating composition comprising: (a) from 0.5 to 90% by weight of at least one epoxy resin, wherein the epoxy resin is solid at 20&#xb0; C., and wherein the epoxy resin is self-dispersing in water; (b) from 0.5 to 90% by weight of at least one (meth)acrylate of a polyol; and (c) from 5.0 to 99.0% by weight of water; wherein the at least one (meth)acrylate comprises at least two (meth)acrylate groups per molecule, and wherein the Brookfield viscosity of the composition is less than 15000 mPas.

Radically post-crosslinked polymers are made by a process comprising the steps of: (1) forming a polyurethane (a*) by reacting a compound (a) with an aliphatic and/or an aromatic isocyanate and a compound (c) wherein compound (a) is the product of the reaction of an epoxidized fatty acid ester and/or an epoxidized triglyceride with acrylic acid and/or methacrylic acid and wherein compound (c) is a polyol ester having two or more C&#x2550;C double bonds per molecule; (2) forming a crosslinked polyurethane by reacting the polyurethane (a*) with a radical initiator (b). The polymers are useful as components in composites comprised of natural and/or synthetic fibers.

Method for producing radically post-cross-linked polymers

The invention relates to epoxy resin hardener compositions containing at least one mercaptan hardener and at least one metal salt of Ccarboxylic acids. These hardeners are distinguished in particular by the fact that catalyzed resins containing epoxy resins and the hardener compositions according to the invention give high-gloss molding compounds, more particularly coatings, after hardening by crosslinking.

Fatty chemical polyalcohols as reagent thinners

The invention relates to a process for producing a polymer or copolymer from monomer material comprising an acrylate, methacrylate, or mixture of such monomers, which comprises the steps of: (a) charging into a continuous tube reactor a feedstock comprising said monomer material and a polymerization initiator; (b) maintaining a flow rate of said material through the reactor at a reaction temperature in the reactor and under pressure sufficient to provide a residence time of the feedstock in the reactor during which polymerization will occur, to form a resin product in the reactor, and said resulting resin product comprising unreacted monomer, and (c) devolatilizing said resin product exiting the reactor to remove unreacted monomers, to provide a substantially monomer-free resin product. Further, the invention relates to resin product made by the process. In particular, the invention relates to resin that has a weight average molecular weight of 10,000 or less, and a glass transition temperature of less than 0&deg; C., preferably &minus;20&deg; C. or lower. The resin product of the invention is particularly useful as an additive for coating and casting resin systems.
