Polyurethane dispersions for adhesive applications

Discusses the manufacture of polyurethane dispersions. States that excellent properties (including good early green strength, high ultimate bond strength, good open time, good adhesion to a variety of substrates, high heat resistance, low heat activation temperature, ability to be blended with other water based polymers and additives) can be obtained with lower environmental impact than for solvent‐based adhesives. Discusses how price/performance can be improved through the addition of less expensive resins. Outlines major applications for polyurethane dispersions in automotive, furniture and footwear industries.
