Title:
METHODS FOR MAKING AQUEOUS POLYURETHANE DISPERSIONS OF AROMATIC POLYISOCYANATE MIXTURES AND COMPOSITIONS THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/123492
Kind Code:
A3
Abstract:
Aqueous polyurethane dispersions made from aromatic polyisocyanates and mixtures of aromatic polyisocyanates and compositions thereof are provided. Advantageously, the methods disclosed herein provide aqueous polyurethane dispersions which are produced more economically with no added organic solvent in the aqueous polyurethane dispersions. Such polyurethane dispersions are environmentally friendly and are useful as adhesives, sealants and coatings for laminating or bonding substrates such as paper, wood, metals, plastics and other synthetic materials.
