Abstract
As sustainability continues to be an industry driver for innovation, bio-based raw materials for organic coatings give formulators the option to create a more sustainable product. However, when formulators consider replacing their petroleum-based raw materials with bio-based counterparts, one might fear coating performance may suffer as a result. This paper compares an industry standard petroleum-based polyisocyanate to a bio-based polyisocyanate when used in a two-component (2K) solvent-borne polyurethane, a 2K solvent-borne fluoropolymer, and a 2K solvent-borne polyaspartic coating. Test results such as pot life, dry times, gloss, and more will be shared to support the theory that bio-based products have similar performance to a petroleum-based counterpart. With these results, the hope is to improve the industry’s perspective on bio-based raw materials and dispel any myths that associate sustainable solutions with lower performance. In addition, this paper serves as an example on how raw material suppliers can help paint manufacturers achieve their sustainability initiatives through the offerings of bio-based alternatives.
