A primer composition for use on fiberglass reinforced polyester substrates combining an ether type low molecular weight epoxy resin, an amino functional silane and halogenated hydrocarbon solvent.

Bonding method employing primer for fiberglass reinforced polyester

This process of adhering sheet roofing materials uses a SBS block copolymer mixed with hydrocarbon resin. No primer is needed, both dry bonding with heat and wet bonding processes have good green strength.

Method of adhering roofing materials

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.

Sealer for polyester and method of use to obtain laminates

An improved two component adhesive whereby said adhesive exhibits sag resistance on a vertical surface substantially immediately after the two components are mixed with adequate gel time for use thereof said two component adhesive being composed of a polyurethane prepolymer component and a curative component mixed at a ratio of 4:1.

Sag resistant two component adhesive and sealant

A polyester adhesive suitable for adhering vinyl films and related materials to wood and metal, the adhesive comprising a water dispersion of a polyester of 10,000 to 30,000 molecular weight range with a carrier and emulsifier.

Aqueous polyester dispersion for adhering vinyl film to wood

A color sensitive primer comprising 100 parts of an ethylenically unsaturated elastomer; 300 to 800 parts of a phenolic resin, A or B stage; 0 to 100 parts inorganic filler; 10 to 30 parts epoxy resin; about 0.5 to 10 parts heat sensitive dye; and about 0.5 to 3 parts sulfur.

Heat sensitive primer exhibiting color change and containing a resin

A polyurethane adhesive that is sandable when cured, the adhesive being the reaction product of a mixture of about one mol of a polyester polyol or polyether polyol of 2-4 hydroxyls having a molecular weight of 500 to about 3000 and 2.5 to 7 mols of isocyanate composition of a mixture of toluene diisocyanate and methane di(phenyl isocyanate) containing a filler composed of silica platelets and glass spherical platelets, a plasticizer amount of polyvinyl chloride plasticizer and a curative amount of monomeric nitrogen containing tetraol of 200 to 1000 molecular weight.

Sandable polyurethane adhesive composition and laminates made therewith

An improved adhesion between polyester compositions per se or metals using the isocyanate-type adhesive is obtained by first treating the surface of the polyester composition and/or metal with a first and a second treating agent without regard to sequence where the first treating agent is an organic polyisocyanate and the second treating agent is a tertiary amine.
