AQUEOUS TWO-COMPONENT DISPERSION ADHESIVE

摘要

Two-component aqueous dispersion adhesive comprises: (a) a first component comprising (a1) at least one polyether-polyurethane polymer, (a2) at least one ethylene vinyl acetate copolymer having a glass transition temperature of more than 0[deg] C and (a3) water; and (b) a second component comprising (b1) at least one polyisocyanate. Independent claims are included for: (1) a method for adhering films comprises mixing the two components (a) and (b), applying the mixed aqueous dispersion adhesive on the surface of a plastic film (2) and the surface of a further substrate (3), ventilating the applied aqueous dispersion adhesive and joining the plastic film and the further substrate by contacting the dispersion adhesive applied on the plastic film and on the further substrate; and (2) a composite body (1) comprising the plastic film and the further substrate, which are bound together by an adhesive (4) that is prepared from the two-component aqueous dispersion adhesive by mixing and subsequently hardening.
