Abstract: A coating composition to improve the physical characteristics of thermoplastic films, such as oriented polypropylene, comprising (1) an acrylic terpolymer of methyl methacrylate, methyl acrylate, and methacrylic acid; and (2) an aqueous-alkali soluble rosin, comprising an adduct of rosin with an alpha-beta unsaturated dicarboxylic acid esterified with a polyhydric alcohol.

Abstract: A retainer device for the decorative trim sheets of upholstered cushions, particularly cushions wherein the padding material constitutes thick slabs of molded rubber or synthetic foam, constituting an elongated flexible structure molded in the padding along the base of a groove formed in the upper surface of the padding, and including a series of opposed pairs of resilient claw teeth spaced along the length of the flexible structure, a fold of the trim sheet, or a flexible secondary listing member affixed to the trim sheet, being pressed downwardly into the padding groove to be securely engaged between the pairs of claw teeth. A listing wire or other strand may be included in the listing of the trim sheet, for more secure engagement by the claw teeth, for neater arrangement of the trim sheet, and for greater ease of engagement by the teeth. The retainer also has other uses, all related generally to the attachment of trim sheets to other elements of seating structures.

Abstract: A silicone resin base fire retardant system having a temperature capability at least to about 450.degree. F (230.degree. C) combines intumescent characteristics with a crusting and charring capability through use of a combination of an oxide of iron and a phosphate of potassium for crusting, along with a charring material such as tripentaerythritol and a blowing agent, such as melamine, in a silicone resin base to allow for adequate expansion.
