Dispersion adhesives

A process for adhesively bonding substrates by mixing a formulation with a coagulant in a two-component spray gun, wherein the coagulant is conveyed separately into the two-component spray gun and is mixed in a spray jet and the coagulation of the dispersion in the spray jet takes place on a path to a surface of a first substrate, on impact with said substrate forms a film which is immediately tacky in a still-wet state and in the wet state a second surface is immediately joined, optionally with pressure on the substrate towards an adhesive surface,

• wherein the formulation comprises:
• I. an aqueous polyurethane or polyurethane-urea dispersion, containing as disperse phase a polymer A) which after drying is semicrystalline or crystalline and has a melting temperature in a range from 30 to 80° C. and an enthalpy of fusion of ≥35 J/g,
• II. at least one plasticizer resin B),
• III. at least one tackifier resin C),
• wherein the formulation, based on the total formulation solids, comprises
• 60%-90% by weight of polymer A),
• 5%-20% by weight of plasticizer resin B) and
• 5%-20% by weight of tackifier resin C), and
• wherein the formulation comprises from 40% to 85% by weight of water.
