Golf club grip protection device

A series of oligomeric adducts of diols and diepoxides are disclosed which are precursors of amine resins for use in electrodeposition coatings. The adducts are epoxide-alcohol addition products of a polyaromatic and/or a mono-aromatic diol and a polyaromatic bis-glycidyl ether, and/or a monoaromatic bis-glycidyl ether and/or an alkoxy arylene bis-glycidyl ether, thioether or amine. The coatings which include amine resin, cross linking agent, grind resin and pigment exhibit excellent corrosion resistance.

Flexible aryl alkyl epoxy resins, their amine resin derivatives and

A compound is described that is useful for metal surface modification, particularly aluminum flake pigment surface modification, having the formula: ##STR1## where X, R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, D.sub.1, D.sub.2, D.sub.3, j, k, m, and n are as defined herein. A method for surface modification of a metallic flake pigment with the compound and compositions containing the surface modified metallic flake pigment is also described.

Treatment of aluminum flake pigment for use in organic coating

A primerless, one-component, moisture-curable polyurethane-based adhesive composition useful for affixing glass panels directly to electrocoat painted metal substrates comprises a polyurethane base polymer containing an electrocoat adhesion promoter. The sealant composition has fast cure times at ambient temperatures and forms a strong bond directly to electrocoat painted metal substrates without the need for a sealant primer.

Room-temperature, moisture-curable, primerless, polyurethane-based

A sealant primer composition useful for promoting the adherence of non-porous materials to enamel paint coated substrates comprises (1) an acrylic polymer base composition comprising the reaction product of 2-sulfoethyl methacrylate and lower alkyl esters of methacrylic acid, (2) a pigmenting agent, and (3) a solvent effective to interpenetrate the enamel substrate coating.

Sealant primer composition and method

A high solids, stable, nonaqueous dispersion, comprising a low Tg copolymer, having a Tg between about -10.degree. C. and about 30.degree. C., particularly adapted for use as a clear coat automotive finish. The copolymer is the copolymerization product of monomers whose Tg is above about 50.degree. C., polar monomers whose Tg is up to about 15.degree. C. and .alpha., .beta. ethylenically unsaturated stabilizer copolymers. The stabilizer copolymers are formed from .alpha., .beta. ethylenically unsaturated monomers and at least one oxirane containing compound and have a molecular weight of about 2,000 to about 25,000, are soluble in aliphatic solvents and have a Tg of about -60.degree. C. to about 0.degree. C. These nonaqueous dispersions result in coatings having high % solids, ease of application, minimal sagging and good gloss and DOI. They are preferably made by copolymerizing ethylenically unsaturated monomers with about 0.5% to about 4% acid functional chain transfer agents and reacting the thus formed copolymer with about 1% to about 4% oxirane containing .alpha., .beta. ethylenically unsaturated monomers to modify the copolymer resulting in a stabilizer copolymer. The nonaqueous dispersion is made by a free radical copolymerization of the monomers whose Tg is above about 50.degree. C., polar monomers whose Tg is up to about 15.degree. C., and the stabilizer copolymers in a nonpolar solvent at reflux temperatures.

Stabilized high solids low Ig copolymer nonaqueous dispersion for clear

The present invention discloses a nonaqueous dispersion of urethane copolymers dispersed in a solvent which is less polar than the urethane copolymer segment wherein the urethane copolymers are the reaction products of a stabilizer, an aliphatic polyol and diisocyanates. Also disclosed is a method for making the nonaqueous polyurethane dispersions.
