Latest Patents
Okitsu's latest patents include a binder composition and a coating composition for decorative paper, both based on polyurethane resin. These compositions utilize a polyurethane resin obtained from a diisocyanate compound and a polyester polyol. The polyester polyol can consist of at least 50% by weight of a polyester glycol with a molecular weight ranging from 500 to 5,000. This glycol is produced by reacting an acid with either 3,3,5-trimethyl-1,6-hexanediol or 2,2,4-trimethyl-1,6-hexanediol. Additionally, the polyurethane resins can be combined with chlorinated polyolefin for use in binder compositions or as coating compositions for decorative paper made from polyolefin resin. Furthermore, these resins can be laminated onto woven cloth made of synthetic resin, which can then be utilized in airbag applications for vehicles.
