Abstract: Adhesive formulations are blends of aqueous polymer dispersions and a hydrophobic plasticizer. The blended dispersed polymers include at least one hard sulfonated polyester urethane, at least one soft non-sulfonated polyester urethane, and at least one polar non-polyurethane water-based polymer or copolymer. A high molecular weight elastomeric non-sulfonated polyurethane polymer and a crosslinker are optional further components in the blend. The formulations are useful as non-heat activating, one-component adhesives which generate excellent green strength, water and heat resistant bonds.

Abstract: This invention relates to new, substantially linear polyester polyurethanes containing hydroxyl end groups, based on selected starting materials, and their use as adhesives or for the production of adhesives.

Abstract: Method of bonding a sole to a shoe by applying moisture-curable melt adhesive to the shoe upper, subjecting the adhesive coating to a hot-cure step with airborne moisture, and pressing the sole and shoe upper together with the adhesive between them immediately after the hot-cure step, preferably in less than 90 seconds after leaving the hot-cure. The bond is effected without application of adhesive to the sole, which is merely pre-treated by wiping with solvent or primer solution.
