Abstract: The disclosure relates to a coating method including the steps of providing a multi-component coating composition including two or more components, applying each component to a porous substrate, mixing each component with at least one other component thereby causing at least two components to undergo a chemical reaction.

Abstract: Target substrates are electrostatically coated by flowing an electrically isolated wet coating composition containing waterborne coalescable polymeric binder into an electrostatic coating apparatus (100), depositing the coating composition onto a rotating electrostatically-charged atomizer (104) and then onto the target substrate, flowing an electrically isolated aqueous cleaning liquid into the apparatus before deposition of the coating composition onto the rotating atomizer is halted or interrupted, and depositing the aqueous cleaning liquid onto the atomizer before or within a sufficiently short time after a halt or interruption in coating composition deposition onto the atomizer so that a coalesced polymeric binder film does not accumulate on the atomizer.

Abstract: A method of bonding two substrates at least one of which is a rubbery polymeric material having carbon-carbon double bonds on the polymer backbone, the method comprising: a) applying an aqueous polyurethane dispersion adhesive composition to at least one of the substrates, the adhesive compostion further comprising an epoxy resin; b) allowing the composition to dry; and then c) joining the substrates with heating to activate the adhesive. The substrates are suitably footwear materials such as a molded rubber outer sole which has been first primed with a chlorinating primer, and a foam midsole of a material such as a lightly crosslinked ethylene vinyl acetate. The process results in bonded assemblies having improved humidity resistance.

Abstract: The present invention discloses a stable aqueous polyurethane dispersions comprising a reaction product of a water dispersible isocyanate-terminated polyurethane prepolymer (A), an aqueous polyurethane dispersion (B) and water, and a method wherein a water dispersible isocyanate-terminated polyurethane prepolymer (A) is dispersed in at least one aqueous polyurethane dispersion (B) and water, and reacted at about 35.degree. C. to about 95.degree. C. until substantially free of isocyanate. The inventive dispersions are useful in adhesives, coatings, binders, primers and sizers.

Abstract: A water-based sulfonated polyurethane composition and footwear manufactured using the composition as as an adhesive, coating and primer. The sulfonated polyurethane is a reaction product ofa) at least one polyisocyanate;b) at least one alkylene diol;c) at least one sulfonated polyester polyol wherein the sulfo groups thereof are present as alkali metal salts; andd) at least one dihydroxy carboxylic acid, or salt thereof. The composition may also be modified to include a dispersed polymer or copolymer of an ethylenically unsaturated monomer. Such mofified compositions may be obtained by preparing the sulfonated polyurethane in the presence of an ethylenically unsaturated monomer and subsequently subjecting the mixture to free-radical polymerization conditions.
