The invention relates to a copolymerizable emulsifier comprising (meth)acrylic acid esters, selected from compounds of the general formula (1) and (II), where: A is an acrylic group having 3 to 40 carbon atoms, x and y independently of each other are a hydrogen group or a methyl group, B is hydrogen or a sulfate or phosphate group, and n a number in the range of 0 to 40. The invention further relates to methods of using said copolymerizable emulsifier in the emulsion polymerization of olefinically unsaturated monomers to prepare polymers.

A defoaming coalescent for a water-based composition including a coalescent carrier; and one or more defoamer-active components is provided. A method for making a defoaming coalescent including the steps of: providing a coalescent carrier and one or more defoamer-active components; and combining the carrier and defoamer-active components is also provided. A water-based composition including a polymer latex or a polymer dispersion; and a defoaming coalescent is also provided.

The invention relates to a curing agent for epoxy resins, comprising a phenalkamine blended with a salted polyamine or a salted polyamine-epoxy adduct to form a curing agent for an epoxy resin, wherein at least one-third of the primary amine groups of the salted polyamine or the salted polyamine-epoxy adduct are blocked.

Biocide compositions capable of increasing the fading resistance of a coating material, which compositions preferably comprise a nano-sized halogenated benzonitrile and a nano-sized zinc oxide, are disclosed. Coating compositions, which comprise the biocide compositions, binders, and pigments are disclosed. The biocide compositions are particularly suitable for use in paints. Methods for reducing the fading of pigmented coating compositions upon exposure to light are also disclosed.

Biocide compositions for use in coatings

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.

Blooming and/or syneresis in gel formulations can be reduced or eliminated by adding to an organic mixture an effective amount of a polyamide gelling agent having a softening point of less than about 105&deg; C. wherein the polyamide is the reaction product of one or more diamines, optionally one or more mono-amines, one or more hydrogenated C36 dimer acids, optionally one or more C dicarboxylic acids, and optionally one or more C monocarboxylic acids.

A curing agent for epoxy resins is prepared by (1) reacting a phenol and an aldehyde in the presence of a basic catalyst to form a first reaction product, (2) reacting the first reaction product with a polyamine or a polyamine-epoxy adduct to form a second reaction product containing unreacted primary amine groups, and (3) reacting the second reaction product with a proton donor compound having a pK value of 11 or less to form the curing agent.

Polyamines and coating compositions with enhanced resistance to yellowing

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.
