Abstract: Resin compositions, soluble in odorless mineral spirits, autooxidizable and air-dryable after application to textiles, leather, wood or other surfaces to form soil, oil and water-repellent coatings. The resin compositions are terpolymers comprising a fluoroaliphatic vinyl monomer, a hydroarbyl higher alkyl vinyl monomer and an acrylic or methacrylic ester of a compound having one or more unsaturated olefinic bonds, which latter ester imparts autoxidizability to the compositions.

Abstract: It has been discovered that by adding one or more strong organic carboxylic acids to conventional acrylate and/or methacrylate based adhesive compositions, the bonding characteristics thereof change dramatically.Thermoplastic materials whose bondability is most dramatically enhanced by the compositions of the present invention are nylon and blends of nylon and nylon-like materials with other polymers.Thermoset materials which exhibit dramatically enhanced bondability comprise homogeneous materials such as epoxies, and composite materials such as polyesters, urethanes, and/or epoxies, containing glass, minerals, and the like, which are polar or have hydrogen bonding capability.The present invention thus utilizes acrylate and/or methacrylate based adhesive compositions as a base material. To this base material is added an effective amount of one or more strong organic carboxylic acids, e.g., acids having a relatively high dissociation constant (K.sub.d or K.sub.1d).

Abstract: A coating composition comprises a water dilutable dispersion of (a) the reaction product of an epoxy resin with a primary or secondary amine and (b) a polymer containing free carboxyl groups. The epoxy resin and amine are preferably reacted in an organic solvent and a solution of the reaction product is mixed with a solution of the carboxyl-containing polymer (b) in an amount sufficient to provide an excess of free carboxyl groups over the amine groups in the epoxy resin reaction product (a). The coating composition is preferably applied to a substrate in the form of an aqueous dispersion in which (a) and (b) are held in stable dispersion by a base such as ammonia or an amine.

Abstract: A process of preparing aqueous dispersions of multi-component film-forming polymer particles, suitable for use in a cathodic electrodeposition process. The disperse particles, which may be thermoplastic or thermosetting, are derived from mixtures of pre-formed polymer and addition polymer formed in situ. The process is carried out at a pH below 10 and in the presence of a selected cationic surface active agent which stabilizes the dispersion below pH 10 but renders it unstable at a pH of 10-11.

Abstract: An abrasive resistant coating is provided for laser trimmable film resistor devices by use of heat-hardenable compositions containing a prepolymer of diallyl isophthalate or diallyl phthalate, an ether alcohol solvent, a heat-curing catalyst and an inert inorganic filler.
