Abstract: The present invention provides an adhesive for floor structure that can provide a floor structure inhibiting floor squeaks or joint gaps from occurring and that enables a floor finishing material to be peeled easily from a sub-floor material when repairing the floor finishing material. The adhesive for floor structure of the present invention contains a hydrolyzable silyl group-containing polyoxypropylene-based polymer (I), calcium carbonate, and a hollow filler. The adhesive for floor structure of the present invention can be used for adhesively integrating a floor finishing material 20 with a sub-floor material 30 laid on a floor base 1.
Abstract: A two-part, solvent-free laminating adhesive including a Part A that is a liquid mixture of a first polyol and a hydroxyl functional acrylic polymer having a molecular weight of no greater than 15,000 g/mole, and a Part B that is an isocyanate-terminated polyurethane prepolymer. The adhesive is especially suited for making flexible laminates for use in food packaging. When adhered two polymeric film materials and in cured form, the adhesive provides substantially no contribution to the oxygen barrier properties of the laminate.
Abstract: The invention relates to a hot melt adhesive composition including an amorphous poly-alpha-olefin, an amorphous propylene/butene copolymer, a grafted polyethylene, and a wax. The hot melt adhesive composition can be used for bonding woven polypropylene substrates. The invention also provides an adhesive bonded woven polypropylene bag.
