Liquid coating compositions having improved mar and scratch resistance are disclosed. The coatings generally comprise one or more particles that have been modified to render the particles more surface active. The improved resistance is achieved without affecting the appearance or mechanical performance of the coatings. Methods for using the coatings, and the substrates coated therewith, are also disclosed.

Liquid coating of film-forming resin and particles chemically modified to lower surface tension

Novel imine functional copolymers are provided containing a plurality of groups of the structure:

Polymeric imine functional compositions and their use in film-forming compositions

Curable compositions containing novel polysiloxanes having various reactive functional groups are disclosed. The curable compositions are useful as both ambient-cured and thermally-cured coating compositions which provide such properties as excellent appearance, mar resistance, acid etch resistance, adhesion, pot life, improved tack time, mar resistance and corrosion resistance.

Curable compositions based on functional polysiloxanes

Coating compositions comprised of (a) a carboxyl functional adduct which is the reaction product of (i) a compound, polymer or oligomer containing pendant and/or terminal hydroxyl or epoxy functional groups and (ii) tartaric acid, malic acid, adipic acid, succinic acid, or anhydrides of said acids; and an anhydride curing agent are disclosed. The coating compositions have accelerated tack-free times and enhanced adhesion to zinc-coated steel and cold rolled steel without the use of a chrome containing wash primer.

Coating compositions with dicarboxylic half ester containing polymers and polyanhydride curing agents

Coating compositions comprising (a) a carboxyl functional adduct which is the reaction product of (i) a compound, polymer or oligomer containing pendant and/or terminal hydroxyl or epoxy functional groups and (ii) citric acid or citric acid anhydride; and (b) an anhydride functional curing agent are disclosed. The coating compositions have accelerated tack-free times and enhanced adhesion to zinc-coated steel substrates without the use of a chrome-containing wash primer.

Carboxyl-functional adduct from oh- or epoxy-functional polymer and

An aqueous two-component polyisocyanate coating composition is based on an essentially isocyanate-free emulsifier that comprises the reaction product of:

Emulsifiers and their use in water dispersible polyisocyanate

A two-component coating composition is disclosed wherein the binder components comprise: (a) an amino component comprising an aqueous solution and/or dispersion of at least one polyacrylate containing amino groups in a quantity sufficient to make said polyacrylate soluble and/or dispersible in water upon neutralization with acid; and (b) a polyisocyanate component containing free isocyanate groups. Also disclosed is the method of emulsifying component (b) into component (a).

Ambient temperature curing aqueous coating composition based on polyurea

A coating composition is disclosed that comprises (a) a copolymer comprising alternating units of a vinyl monomer and an unsaturated diester monomer in which at least one of the esterifying groups includes a hydroxyl group, and (b) a hydroxy group-reactive curing agent. The diester monomer is formed by first opening an anhydride with an alcohol to form a monoester, and then alkoxylating the remaining acid group on the monoester with an epoxy compound to form a second ester group having hydroxyl functionality.
