Fabric coatings, vinyl resins

Vinyl resins are widely used as fabric coatings because of their combination of toughness and flexibility, and their property of not supporting combustion. Because they are nonflammable they replaced nitrocellulose lacquers for many applications on fabrics. They produce excellent coatings on metals but care must be taken in their application because, like most high polymers, they have strong cohesive forces that may overcome the adhesive forces. The entire coating may flake off as a continuous sheet if the precise application conditions have not been complied with for the various modifications.

Table A.6 shows that many other vinyl, allyl, isopropenyl, and other ester copolymers and their derivatives have potential uses as emulsifiers, dispersants, adhesives, coatings, photoreactive resins, aqueous thickeners, oil additives, and others. Allyl acetate-MA copolymer sodium salt is comparable to sodium tripolyphosphate as a detergent builder. In addition, the copolymer provides protection of the fabric against sodium perborate damage.

Basically a plastic composite is the assembly of two or more materials made to behave as a single product. Examples include vinyl-coated fabric used in air mattresses or laminated metal bonded together with a plastic adhesive used in helicopter blades. The RP type of composite combines a plastic with a reinforcing agent that can be fibrous, powdered, spherical, crystalline, or whisker, made of organic, inorganic, metallic, or ceramic material. To be structurally effective, there must be a strong adhesive bond between the resin and reinforcement. 

The selective hydrogenation of an olefinic bond in crotonaldehyde gives n-butyraldehyde in presence of a suitable catalyst n-butyraldehyde reacts with poly (vinyl alcohol) to form poly (vinyl butyral) which is used as an interlayer for safety glass as well as for coating fabrics and for injection-moulding compositions. Butyraldehyde also finds use in making oil-soluble and alcohol-soluble resins. Butyraldehyde is a raw material for the manufacture of butyric acid and butyric anhydride... 

It was not until the commercialization of synthetic plastics resins in the 1930s that an almost unlimited variety of base materials became available for compounding into adhesives and sealants. Most of the thermoplastic resins were soluble in organic solvents and were used as solvent adhesives for molded plastic articles of the same base composition and sometimes for other materials. Poly(vinyl chloride) (PVC), a thermoplastic developed in 1927, is used today in solvent formulations to bond PVC articles such as coated fabrics, films, foams, and pipe. In the early 1930s, phenolics came into importance as adhesive resins. Before that time they were used as coating varnishes [9, p. 239). About 1931 development of the use of a new phenolic resin for plywoods and veneers began [9, p. 239].
