Title:
UV-RESISTANT FLOCKING ADHESIVE FOR POLYMER SUBSTRATES
Document Type and Number:
WIPO Patent Application WO2002038693
Kind Code:
A3
Abstract:
The invention relates to two-component polyurethane bonding agents based on a polyester polyol comprising an aliphatic or cycloaliphatic polyisocyanate and a hardening component based on a polyamine mixture, suitable for use as UV resistant flocking adhesives for the flocking of polymer substrates. Said adhesives can be incorporated into all known processing methods and enable flocked articles with a higher UV-resistance and good abrasion resistance to be produced.
