Luphen® 3695

Luphen®
3695 is a 50% aqueous dispersion of an aliphatic polyesterpolyurethane
elastomer. The formed film can be activated by heat at 55-60 °C enabling the
manufacture of heatsealing adhesives.  Luphen®
3695 has a limited hot-tack life.

 

General

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.
