The process of this invention uses a single primer and a fast curing two component adhesive sealant to adhere automotive glass surfaces to coated metal surfaces.

Primer and sealant for glass and coated metal

Improved two component adhesives allowing the components to be mixed at essentially a 1:1 ratio, giving excellent sag resistance, low viscosity, excellent handling ability and satisfactory gel time, said adhesives being composed of a prepolymer composition and a curative composition that can be mixed preferably at 1:2 to 2:1 ratio and a curative composition composed of a mixture of a reaction product of a multiple hydroxyl polyol of relatively low equivalent weight with a small amount of an organic polyiisocyanate and a polyamine.

Sag resistant at essentially 1:1 ratio two component adhesive

A sealer for solid polyester composition to reduce evolution of vapors at temperature 190.degree. C. or higher for 1 hour or more and to improve the bond at these temperatures with isocyanate polyurethane adhesives, epoxy adhesive or acrylic adhesive, the sealer comprising a mixture of 100 to 1000 parts of phenol-formaldehyde resin, 90 to 110 parts of a polyvinyl acetal resin, 10 to 40 parts of epoxy resin, and sufficient solvent to render the mixture brushable, sprayable or flowable.
