3685 is a 40% aqueous dispersion of a polyester polyurethane elastomer. The
formed film can be activated by heat at 60-65 °C enabling the manufacture of
heat-sealing adhesives. Luphen® 3685 has a limited hot-tack life. Luphen® 3685
is used in several application such as 3D furniture lamination, interior trim
and shoe sole attachment. Specially developed water-emulsifiable,
polyfunctional isocyanates such as Basonat® -types should be added to adhesives
formulated with Luphen® 3685 to improve the heat resistance of the bond and its
resistance to hydrolysis.
