A method of forming an adhesive bond between two surfaces to form a bonded structure involves the steps

Method for preparing an adhesive bond with a curable composition having

Curable epoxy based compositions having reduced shrinkage during cure

A polymerizable ethylenically unsaturated urea urethane polymer dispersed in a polymerizable ethylenically unsaturated compound is prepared by a process which comprises reacting a polyisocyanate, at least a portion of which is a diisocyanate, with a polyfunctional amine containing primary and/or secondary amino groups in the presence of:

Polyurea-polyurethane acrylate dispersions

Disclosed is a method of coating a substrate comprising the steps of (A) coating the substrate with one or more applications of a basecoating composition containing (1) an organic film-forming resin, (2) substantially colorless, substantially inorganic microparticles stably dispersed in the basecoating composition, (3) a solvent system for the film-forming resin, and (4) pigment particles to form a basecoat; and (B) coating the basecoat with one or more applications of a topcoating composition containing (1) an organic film-forming resin, and (2) a solvent system for the organic film-forming resin of the topcoating composition, to form a transparent topcoat. The substantially inorganic microparticles prior to incorporation in the basecoating composition range in size from about 1 to about 150 nanometers.

Color plus clear coating system utilizing inorganic microparticles

A curable composition which contains polyepoxide and amine curing agent free of amide groups and which is of a substantially lower viscosity than the polyepoxide is improved by thickening the amine to a viscosity comparable to that of the polyepoxide. The amine is thickened by either incorporating into the amine curing agent a polyamide in an amount not exceeding 35 percent by weight based on the amount of amine curing agent of a polyamide; or converting a portion of the amine curing agent to polyamide by in situ chain extension to form amide groups wherein the chain extension is carried out in an excess of amine curing agent before the amine curing agent is admixed with the polyepoxide component of the curable composition; or a combination thereof.

Use of a polyamide to thicken an amine

Disclosed is an essentially solvent-based, organic, high-solids coating composition containing (A) a film-forming binder system containing a crosslinkable resin having a weight average molecular weight of from about 500 to about 10,000; (B) substantially colorless, substantially inorganic microparticles stably dispersed in the coating composition; and (C) a solvent system for the crosslinkable resin. The substantially inorganic microparticles prior to incorporation in the coating composition range in size from about 1 to about 150 nanometers and are in the form of a sol of the microparticles in which the surface of the inorganic microparticles is essentially free of carbon-containing molecules chemically bonded to the inorganic microparticles.

High-solids coating composition for improved rheology control containing

Disclosed is an essentially solvent-based, organic, high-solids coating composition containing (A) a film-forming binder system containing a crosslinkable resin having a weight average molecular weight of from about 500 to about 10,000; (B) substantially colorless, substantially inorganic microparticles stably dispersed in the coating composition; and (C) a solvent system for the crosslinkable resin. The inorganic microparticles prior to incorporation in the coating composition range in size from about 1 to about 150 nanometers and are in the form of a sol of the microparticles in which carbon-containing molecules are chemically bonded to the inorganic microparticles at the surface of the microparticles.
