METHODS FOR MAKING AQUEOUS POLYURETHANE DISPERSIONS OF AN AROMATIC POLYISOCYANATE AND COMPOSITIONS THEREOF

摘要

The present invention is directed to aqueous polyurethane dispersions of an aromatic polyisocyanate and compositions thereof. 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.
