International Classification:

B29C 41/02
B29C 45/16

US Classification:

264 464, 156247, 264 54, 264261

Abstract:

The invention is a process for the preparation of article comprising placing a film on each inner surface of each part of a two part mold; placing an article in the mold with film located between the surface of the mold and the article such that there is a small space between the article and the surface of the mold; closing the mold about the article; injecting between the film and the article an expandable plastic material under conditions that the article is coated with the expandable material and the expandable material does not expand; removing the plastic article with the expandable material coated thereon with the two films attached to the expandable plastic material. In another embodiment the invention is an article comprising a shaped plastic article; an expandable material coated in the shaped plastic article; and a film covering the material coated shaped plastic article. In another embodiment the invention is a method of reinforcing a structural member which comprises inserting an article according to this invention into a cavity of the structural member and heating the structural member and the article to a temperature at which the expandable plastic material expands and the film or the expandable material bonds to the inner surface of the structural member so as to fix the location of the article in the structural member.

B05D 3/12

US Classification:

427292, 524590, 525454, 4274275

Abstract:

A polyurethane coating composition, sprayable onto a substrate by means of conventional spray equipment at pressures of less than about 100 psi and at temperatures of between ambient to about 50 C., in one or more layers to a film thickness of up to about 30 mils, comprises a resin component having hydroxyl functionality, which may be substantially free of amine functionality, an isocyanate functional curing component, an organotin catalyst, and a catalyst inhibiting amount of a volatile organic acid. The composition may optionally include a fibrous reinforcing material, and a colorant. Advantageously, the coating compositions of the present invention provide polyurethane films having excellent physical properties, solvent and UV resistance, and adhesion to clear coated substrates without the need for adhesion promoting primer coats or chemical pretreatments. The compositions are particular useful to form sprayable vehicle bedliners.
