Abstract: A polymeric mixture comprising a graft copolymer of silicone resin is useful as a polymeric binder in paint coatings and particularly powder coatings. The polymeric mixtures are produced by copolymerizing ethylenically unsaturated monomers including glycidyl monomers in the presence of silicone resin to produce the graft silicone resins.
Abstract: A water-dispersed protective coating composition contains a coreactive binder comprising a polycarbodiimide adapted to crosslink with a carboxyl functional emulsion copolymer and polyurethane. The coating is applied to plastic substrates and ambiently cured or with mild heat.
Abstract: An aqueous dispersed primer-sealer composition applied to a surface layer of overlay paper or surface mat provides an impregnated surface layer for use in manufacturing hardboard products by hot pressing in a molding operation. The primer sealer provides a finished surface as well as defect-free surface from the molding surface. The primer-sealer can be pigmented and is based on a polymeric binder composition containing melamine resin, carboxyl functional acrylic emulsion copolymer, vinyl-acetate-vinyl versatate copolymer, emulsified fatty acid, and polyvinyl alcohol.
Abstract: Phenoxy terminated epoxy resins are grafted by carbon-carbon graft with ethylenic monomers, including alkylol acrylamide monomer, by in-situ polymerization to produce grafted epoxy-acrylic copolymers useful as binders in protective coatings. The cured paint films exhibit superior resistance to pine oil and limonene derivatives.
Abstract: Ionomeric paint coatings are produced from an ionomeric polymer containing carboxyl functionality which is coreacted or neutralized with an organic zinc salt. The ionomeric polymer coreacted with a zinc organic salt functions as a binder and exhibits thermosetting-like properties.
Abstract: Non-aqueous ionomeric coatings useful as protective surface coatings applied to a substrate are produced by combining a carboxyl functional polymer with zinc carbonate. Upon heat curing the applied film, the zinc cation clusters with the carboxyl polymer to produce a thermoset coating film.
Abstract: A two piece slip-sinker for use on fishing lines comprises a two sectional sinker adapted to separate at a linear disposed, axial central opening to receive a fishing line. The two piece slip-sinker is maintained as a unitary sinker by means of an elastomeric O-ring engaging a circumferential periphery channel disposed in the outer surface of the assembled slip-sinker and orientated transverse to the axial through opening. The two piece slip-sinker contains internal engaging means for interlocking the interface surfaces of the two sections and prevent interface movement between the two sections while locked in place by the elastomeric O-ring.
Abstract: Heat cured, thermoset protective surface coating films applied to a substrate are produced preferably by a dual cure of a polymeric ionomeric binder comprising zinc modified carboxyl functional epoxy-ester polymers. The epoxy-ester polymer contains both carboxy and hydroxyl functionality and coreacts with a zinc salt selected from a zinc carbonate or an organic zinc salt having a pKa above about 3.0. Upon heat curing, the carboxyl and hydroxyl groups crosslink while the zinc forms a zinc cluster to produce a thermoset film.
Abstract: The pigmented paint coating composition is based on a cationic free polymeric binder comprising a cationic free, functional emulsion polymer and glycoluril where the emulsion polymer are adapted to coreact to form a thermoset paint film, and said polymeric binder is combined with a low-cation opacifying pigment. The process comprises copolymerizing ethylenically unsaturated monomers, including functional monomers but excluding amine monomers, in an aqueous polymerization medium, to produce the reactive emulsion polymer. The emulsion polymer and the glycoluril derivative are treated with ion-exchange step to produce the cation-free polymeric binder.
Abstract: An elastomeric cap fitted to a circular valve handle of a fluid shut-off valve comprises a polygonal solid ring structure having an open center and containing a plurality of radially directed sockets molded in the ring structure. The sockets are adapted to engage circumferentially spaced peripheral lobes of the circular valve handle.
Abstract: A heart-shaped, free standing, living plant comprises at least two living plants, a left plant and a right plant, formed into opposed lobes forming the heart configuration. Each plant comprises a root end, an intermediate trunk section and a foliage end. The root ends are secured together and the intermediate trunk sections form the left lobe and right lobe respectively. The foliage ends extend laterally outwardly from the downwardly depending intermediate trunk sections to form a foliage midsection of the heart-shaped plant. A support means is provided during the initial growing period wherein the heart-shaped plant is permanently formed. Thereafter, the support means can be removed to form a free-standing, unsupported living plant.
Abstract: A stabilized aqueous, thermosetting coating composition substantially free of acid cure catalysts comprises a mixture of an ion-exchanged reactive function emulsion polymer and a glycoluril derivative adapted to coreact and crosslink the functional polymer where certain cations are added to the ion-exchanged mixture to provide a pH of the mixture between 2 and 5.

Abstract: An improved thermosetting coil coating composition contains a binder of a thermosetting polyester polymer particularly resistant to crystallization and adapted to be crosslinked with an aminoplast resin. The polyester comprises the condensation copolymer of 2-methyl-1,3-propane diol, neopentyl glycol, isophthalic acid, and terephthalic acid.

Abstract: Curable epoxy-amine coatings comprised of pigmented mixtures of reactive amine-functional curing agents and epoxy resins are substantially improved by being rendered thixotropic or pseudoplastic by the inclusion of at least about 0.05% by weight of a thixotropic additive selected from monocarboxylic organic acid, dicarboxylic organic acid, tricarboxylic organic acid, fatty acid or polymerized fatty acid.
