UV-REACTIVE HOT-MELT ADHESIVE FOR LAMINATING TRANSPARENT FILMS

摘要

The invention relates to a UV-curable hot-melt adhesive for laminating transparent films, in particular on molded bodies made of wood materials which are coated with melamine or PVC. The hot-melt adhesive contains at least one UV-curable urethane(meth)acrylate. The urethane(meth)acrylate can be obtained by converting an NCO-functional polyurethane prepolymer with a molar excess of hydroxy and/or amine-modified(meth)acrylate; at least one (meth)acrylate monomer or oligomer, said at least one (meth)acrylate monomer and/or oligomer comprising an acid-modified (meth)acrylate with an acid number of 50 to 400 mg KOH/g; and at least one photoinitiator. The invention likewise relates to a method for coating a molded body with a film using said hot-melt adhesive and to the composite materials produced in this manner.
