The Waterborne Symposium

A new water-borne resin technology that utilizes polyamide-based polyols as the soft segment in polyurethane dispersions has been developed. Coatings based on this patented resin technology can provide solvent-borne like performance including high levels of hardness, abrasion resistance, and chemical resistance in an easy to use 1K water-borne system. Typically, the solids content for waterborne polyurethane dispersions is lower than acrylic emulsions. This novel polyamide-based technology can produce high solids (< 50% solids) waterborne dispersions, which approaches the limits of acrylic emulsions while maintaining the polyurethane hardness. This presentation will cover, how increased solids content has several benefits for coatings applications including; the elimination of a coating step, higher film build, reduction of dry time, and lowered coalescing solvent demand. The combination of these advantages and the well-known high performance of the polyamide-based urethanes is expected to be a valuable benefit in a variety of different coating applications.
