The present invention relates to pressure sensitive adhesives based on aqueous latex emulsions processes for their preparation and laminates the prepared there from. The pressure sensitive adhesives exhibit excellent adhesion in hot water environments and resistance to water-whitening.

Pressure sensitive adhesives

Plasticizer resistant latex emulsion pressure sensitive adhesive and its production

An solvent-based pressure sensitive adhesive (PSA) having improved shear adhesion is composed of an acrylic-based PSA resin, an ethylenically unsaturated polyester, an ultraviolet radiation (UV) photosensitizer, and fugative organic solvent for the acrylic-based PSA resin. The PSA is cured by evaporation of the fugative organic solvent coupled with heat and UV irradiation or UV irradiation alone. Such PSA has improved shear adhesion by dint of the addition of the ethylenically-unsaturated polyester and an ultraviolet radiation (UV) photosensitizer. A method for adhering two substrates using the PSA includes applying the PSA to one or both of substrates. The solvent in the PSA is evaporated from the applied PSA. Finally, the polyester component of the applied PSA is cured by exposure of the applied PSA to ultraviolet (UV) radiation.

UV post curable pressure sensitive adhesives for membrane switch applications and their Production

Epoxy resin, thermoplastic polymer and hardener adhesive

Blends of polyamide polyols and urethane diols are prepared by reacting alkyl (methyl) esters of polybasic acids (preferably dibasic acids) with excess alkanolamine (preferable ethanol amine propanol amine) to form the polyamide polyol of the polybasic acid and alkyl alcohol. The alkyl alcohol is removed and the excess ethanolamine is reacted with ethylene or propylene carbonate to form the urethane diol. This blend of urethane diol and polyamide polyol is useful in various polymer formulations.

Fast curing adhesives which are free of solvent and have high heat resistant bonding strength composed of mixtures of polyols, polyepoxides and polyisocyanates are described.

Polyol/polyepoxide/polyurethane adhesive

The process for preparing novel polymers by the reaction of a bicyclic amide acetal with sulfur at a temperature in the range of from about 25.degree. C. to about 200.degree. C. is described.

Reaction of bicyclic amide acetal with sulfur

An adhesive comprising a mixture of (A) a mixture of an isocyanate prepolymer and a polyepoxide which is essentially free of hydroxyl groups, and (B) a mixture of a polyol, a urethane catalyst and an epoxy curing catalyst and structures prepared by adhering substrates to one another by means of said adhesive are described.

Sag resistant two-component urethane adhesives with improved thermal

Surface modification of inorganic fillers by treatment with bicyclic

An improved process for preparing bicyclic amide acetals from an organic nitrile and a dialkanol amine wherein the reaction temperature is maintained in the range of from room temperature to 140.degree. C., and the bicyclic amide acetal product is removed from the reaction mixture by extraction into a hydrocarbon or organic nitrile solvent prior to its purification is described.

Bicyclic amide acetals are prepared from organic nitriles and dialkanol

A process for removing water from its mixture with hydroxyl containing compounds by adding a bicyclic amide acetal to such mixture and allowing the water to react with the bicyclic amide acetal is disclosed.

C. is described.
