A coating apparatus and process for coating selected surface areas of extruded substrates with decorative or functional coatings by passing the extruded substrates emerging from the extrusion die through a coating block. The coating block contains a coating cavity die conforming to the selected surfaces to be coated wherein liquid coating is supplied to the coating cavity die in a manner to selectively coat the selected surfaces on the extruded substrate.

A coating blend composition is a physical admixture of an adhesion promoter resin and a coating material resin. The blend can be cured by one or more curing agents existing within either the adhesion promoter resin, the coating material resin, or both. The utilization of such a blend eliminates the need for priming a substrate such as a rubber, or a thermoplastic or a thermoset polyolefin. The adhesion promoter resin is a urethane composition containing a blocked polyurethane prepolymer whereas the coating material resin can generally be any compound which has a functional or cosmetic purpose such as a different type of blocked polyurethane, and is generally utilized in a major amount. A particular application of the coating blend compositions of the present invention is to a glass run channel made from, for example, EPDM, as in an automotive door.

A shock absorber mount is described as having two pressed fittings which are mounted in end-to-end relationship. Each insert has two rigid, radially spaced cylindrical sleeves which are separated by a resilient rubber insert. The inner sleeve of the vertically lowermost fitting, when the fittings are properly mounted on, for example, an automobile frame, extends upwardly beyond the associated outer sleeve and is coated with rubber to enter a hollow bore formed by the inner sleeve of the upper fitting. The extension allows the lower fitting to initially absorb an upwardly applied axial force until it moves into shock absorbing relation with the upper fitting. The extension also acts to bolster the radial shock absorbing characteristics of the upper fitting to provide improved shock absorbing characteristics of the mount; namely, low axial shock absorption and high radial shock absorption.

A process for mechanically bonding a sheet of rubber to a sheet of another, e.g. a reinforcing, material, and a composite article made by the process. A molded sheet of rubber having integral upstanding posts is assembled with the sheet of the other material in such a manner that the posts extend through openings in the sheet of the other material. The distal ends of the rubber posts are then reformed (preferably by heating) to shape or form the rubber posts into rivets which mechanically lock the rubber sheet and the sheet of other material together and provide good shear resistance. According to another embodiment of the present invention, the reinforcement material is a high melting temperature plastic which has an upstanding post and the molded rubber sheet and has openings therein. The plastic posts are reformed as with a laser to bond the plastic sheet to the rubber sheet.
