An interpenetrating polymer system prepared from a mixture of a moisture-cured prepolymer component and elastomeric component which is non-reactive with the prepolymer component, wherein exposure of the mixture to ambient moisture cures the prepolymer component entrapping the elastomeric component and forming a product which is essentially thermoset. The product may be essentially non-foamed or highly foamed and and either tack-free or self-adhesive. It is particularly suitable for use as sealing gaskets, sheet stock, tubing, and as sealant-encapsulants.

Moisture cured elastomeric interpenetrating network sealants

Gasket formed in place on a surface of an article by producing an initial elongated bead of a selected cross-sectional area and bringing a mold cavity having the same cross-sectional area into contact with the surface to produce the final shape of the bead on the surface.

Method for forming flexible gaskets

Hollow bodies are sound insulated by placing partial dams inside of the hollow bodies and filling the bodies with a polymer composition. The partial dams facilitate more complete filling of the hollow bodies with the polymer composition which is fluid when injected into the bodies.

Process of sound insulation of hollow bodies

Skis of laminated construction are assembled by joining the several lamellae with a hot melt adhesive which preferably contains an effective amount of an adhesion promoting agent. The hot melt adhesive is preferably a linear polyester, polyesteretheramide, polyetherester, polyamide, polyetherurethane, copolymer of ethylene-vinylacetate, polyesteramide, or polyetheramide, and when the adhesive is based on a copolymer, it is more preferable still that the copolymer is a block copolymer.

Ski construction

Skis of laminated construction are assembled by joining the several lamellae with a hot metal adhesive which preferably contains an effective amount of an adhesion promoting agent. The hot melt adhesive is preferably a linear polyester, polyesteretheramide, polyetherester, polyamide, polyetherurethane, copolymer of ethylene-vinylacetate, polyesteramide, or polytheramide, and when the adhesve is based on a copolymer, it is more preferable still that the copolymer is a block copolymer.

Drums of moisture or air sensitive materials are protected by placing on the exposed surface of the material, a layer of a fluid second material that is essentially impervious to air and moisture and is neither soluble nor miscible in the material being protected.

Container sealing means for air and moisture sensitive materials

The invention relates to a thermoplastic pressure-sensitive adhesive composition. The thermoplastic pressure-sensitive adhesive composition according to the invention comprises as essential elements a styrene-isoprene-styrene elastomer, at least one tackifying resin selected from aliphatic hydrocarbon, C8-aromatic and terpenephenolic resins and a block copolymer with elastomeric and rigid segments selected from copolyetheresteramides and copolyetheresterurethanes. It further preferably comprises a tackifying naphthenic oil and fillers. The composition according to the invention is particularly useful for bonding decorative streeps, protective rubber trims, mirrors, etc to panel bodies of painted cars and is therefore resistant to heat and gasoline.
