Airable has formulated a soy-based, non-isocyanate polyurethane dispersion that shows good adhesion to wood, leather, and aluminum metal. The waterborne resin has no volatile organic compounds (VOCs). Airable has investigated the soy dispersion as a coating and is exploring other applications such as adhesives, sealants, and elastomers.
Overview
Airable Research Lab has formulated a soy-based polyurethane dispersion. This material utilizes our carbonated soy platform to transform the cyclic carbonates on soy to yield polyurethanes without requiring the use of sensitizing isocyanates. The waterborne resin has no volatile organic compounds (VOCs). Polyurethane dispersions are used in coatings, adhesives, sealants, and elastomer applications. Airable has investigated the soy dispersion as a coating and is exploring other applications.
