Abstract: One aspect of the present invention is a spray gun adapted for spray-applying fiber-reinforced resins with ceramic fiber loadings of at least about 55 wt-%. Such novel spray gun has an inlet for admitting the fiber-reinforced resin; an air inlet for atomizing the fiber-reinforced resin; a catalyst inlet; and an outlet for expelling catalyzed fiber-reinforced resin from the spray gun. The spray gun also has a straight-line delivery channel in fluid communication with the resin inlet, the catalyst inlet, and the outlet. A flow actuator is provided for selectively actuating admission of the fiber-reinforced resin and the catalyst into the spray gun. The resin inlet and the catalyst inlet are disposed for admitting resin and catalyst, respectively, in line into the straight-line delivery channel.

Abstract: The liquid oligomeric compositions of this invention are made by the Michael addition reaction of acetoacetate functional donor compounds with multifunctional acrylate receptor compounds where the equivalent ratios of multifunctional acrylate to acetoacetate vary from .gtoreq.1:1 to .gtoreq.13.2:1 depending on the functionality of both multifunctional acrylate and acetoacetate. Unuseable gelled or solid oligomer products occur below the claimed ranges. The liquid oligomers of this invention are further crosslinked to make coatings, laminates and adhesives.

Abstract: This invention is a preapplied liquid adhesive whose components, when dried and heated, react to form a polymer. Laminates made with the thermoset adhesive withstand exposure to 240.degree. F. (116.degree. C.). The adhesive combines urethane dispersions, carboxyl functional acrylic latices and tertiary amine blocking agent.

Abstract: This invention is the addition of an polyaldimine or polyketimine to the curative component of a two part polyurethane structural adhesive for bonding car, boat and truck parts.

Abstract: This invention is a thermoplastic saturated polyester low profile additive (low profile additive) useful in sheet molding compounds for parts, especially vehicle parts. The additive has a major component derived from aromatic compounds such as terephthalic acid including recycled polyethylene terephthalate. Asymmetrical glycols are an important ingredient and can be used to digest recycled PET to make oligomeric glycols which are reacted with acids having fewer than 12 carbon atoms to make one of the low profile additives of this invention.

Abstract: This invention is the addition of an aldimine to enhance the ability of thermoplastic low profile additives to improve the surface quality of cured sheet molding compound vehicle parts.

Abstract: Vinyl ester resins processed until low epoxy values are reached are storage stable for two weeks at 54.degree. C. (130.degree. F.). Adding a copper salt inhibitor also provides two weeks storage stability at 54.degree. C. (130.degree. F.). A synergistic effect is observed if both low epoxy values are reached and copper naphthenate inhibitor is used, extending shelf life stability to two months at 54.degree. C. (130.degree. F.).

Abstract: This invention is a method of using a heat activatable adhesive for laminating vinyl sheet to wood. The organic solvent-free adhesive combines a reactive styrene-acrylic latex emulsion, an ethylene vinyl acetate copolymer emulsion, and a wax. After application to the vinyl substrate the adhesive is heat activated at temperatures as low as 160.degree. F. (71.degree. C.) and the laminate resists delamination at 190.degree. F. (88.degree. C.).

Abstract: A tacky pressure sensitive water-borne acrylic emulsion adhesive composition prepared with >1% multifunctional monomer has Tg<0.degree. C., >90% gel content and is web coatable. The dried adhesive film anchors readily and remains easily removeable from diverse substrates.
