This invention provides for reinforced wood structures including framing members and a method to reinforce the connection between structural members to increase the load bearing capacity of framing member intersections by covering the intersecting wood framing members with a layer of a liquid elastomer including polyurea.

Strengthening wood frame construction against wind damage

A coating composition contains a carbamate-functional film-forming material, a carbinol-functional, nonlinear siloxane resin, and an aminoplast crosslinking agent. The composition provides excellent high-bake repair adhesion of a repair-coating layer over the initial coating.

Coatings with carbinol-functional siloxane resin

The invention provides a clearcoat coating composition containing either one acrylic polymer with secondary hydroxyl functionality and carbamate functionality or two acrylic polymers, the first having secondary hydroxyl functionality and the second having carbamate functionality; a carbamate-functional or urea-functional material that is the reaction product of (1) a compound comprising a primary carbamate or primary urea group and an hydroxyl group and (2) a compound that is reactive with hydroxyl groups on a plurality of molecules of compound (1), but that is not reactive with the carbamate or urea groups on compound (1); and a crosslinking component including an aminoplast crosslinker. A windshield sealant can be applied directly to the clearcoat layer produced from the composition without the need for a special primer layer.

Clearcoat composition for primerless MVSS adhesion

The invention provides coating compositions comprising a reactive component (a) which is substantially free of any heteratoms and is a not a crystalline solid at room temperature and which comprises from (i) 12 to 72 carbon atoms, and (ii) at least two functional groups, and (b) a crosslinking agent comprising a plurality of functional groups (iii) reactive with the functional groups (ii) of compound (a), wherein functional groups (ii) and (iii) are selected such that reaction there between produces a thermally irreversible chemical linkage. The coating compositions of the invention provide improved solids, chip resistance, flexibility and/or scratch & mar resistance while maintaining desirable and/or improved performance characteristics with regard to environmental etch, relative humidity, QCT, chip resistance, thermoshock resistance, cold crack resistance, adhesion and the like.

Coating composition containing crosslinkable monomeric difunctional compounds having at least thirty carbon atoms

Clearcoat coating composition for automotive exterior coatings with improved intercoat adhesion to a subsequently applied coating layer and improved flexibility contains (a) a first vinyl copolymer prepared from a monomer mixture including no more than about 35% by weight of nonfunctional monomers that has carbamate functionality and hydroxyl functionality, at least part of the hydroxyl functionality being on monomer units including an optionally branched alkyl group having at least about six carbon atoms; (b) a second vinyl copolymer having hydroxyl functionality, preferably primary hydroxyl functionality; and (c) a curing agent component that includes at least an aminoplast curing agent and optionally a polyisocyanate curing agent. The polyisocyanate curing agent is preferably blocked with a blocking agent that volatilizes during the cure reaction, regenerating a reactive isocyanate group.

Clearcoat composition with improved adhesion

Coating compositions containing crosslinkable monomeric difunctional compounds having at least thirty carbon atoms

The invention provides a method of coating a substrate with first a layer of a chip resistant primer composition that has as a resinous portion a polyurethane polymer having a glass transition temperature of 0&deg; C. or less and, optionally, a second component that has reactive functionality; and next with a layer of a thermosetting primer composition including a polyurethane polymer having a glass transition temperature of 0&deg; C. or less, an acrylic polymer having a glass transition temperature that is at least about 20&deg; C. higher than the glass transition temperature of said polyurethane polymer, and a crosslinking component that is reactive with at least one of the polyurethane polymer and the acrylic polymer; and finally with at least one layer of a topcoat composition. The reactive functionality of the second component is reactive with at least one polymer selected from the group consisting of the polyurethane polymer of the chip resistant primer composition, the polyurethane polymer of the thermosetting primer composition, the acrylic polymer of the thermosetting primer composition, and combinations thereof.

Composite coating with improved chip resistance

Method of coating electrically conductive substrates, aqueous electrodip

The invention relates to a novel electrocoating composition for metallic substrates that exhibits 'thick-build' protective properties at 'medium-build' thicknesses. It is composed of a self-addition epoxy resin-polyamine adduct, a blocked isocyanate cross-linker, a polyglycol-polyamine grind resin, a plasticizer, an anti-cratering agent and pigments.

Polymeric reaction products

Plasticizing resins, aqueous dispersions of cationic resins, and methods of making the same for use in cathodic electrodeposition are disclosed. The resins are formed from reacting a polyoxyalkylenepolyamine, a phenol, and a formaldehyde. The reactants may further include a block building unit derived from a polyepoxide. When used in combination with other conventional electrodepositable resins, deposited films with improved mechanical properties and descreased tendency toward cratering are obtained.
