Luphen® 3695

Luphen® 3695 is a 50% aqueous dispersion of an aliphatic polyester polyurethane elastomer. The formed film can be activated by heat at 55-60 °C enabling the manufacture of heat-sealing adhesives. Luphen® 3695 has a limited hot-tack life. With its very low activation temperature the Luphen® 3695 is used in several application such as 3D furniture lamination and interior trim, as blending component especially in combination with Luphen® 3615 or Luphen® 3644. Specially developed water-emulsifiable, polyfunctional isocyanates such as Basonat® types should be added to adhesives formulated;with Luphen® 3695 to improve the heat resistance of the bond and its resistance to hydrolysis.
