Description:

The Phase I project showed that novel urethane-functional (NUF) resins could be produced that were free of isocyanates and very  useful or one-component, ambient-cured (OCAC) coatings. Resins for OCAC coatings, which are expected to be valued at $5.7 billion by  2019, are used to produce a variety of coatings including oil-based paints, wood stains, varnishes, and aerosol paints. Phase I results showed that NUF resins could be used to overcome a major limitation associated with the current state-of-the-art for OCAC coating resins. This limitation is the ability to significantly reduce the level of solvent in the coating without sacrificing coating performance characteristics, such as drying/curing time, durability/hardness, and chemical resistance. Thus, NUF resins provide high performance OCAC coatings with substantially lower levels of air pollutants (i.e. solvents). An added environmental benefit associated with NUF resins are their ultra-high biobased content. Coatings with a high biobased content are better for the environment and reduce our Nation's dependence on fossil resources. In addition, coating resins with a high biobased content enable product preference incentives for the coating supplier or coating end-user. Results from the Phase I project were shared with multiple potential customers and their support for further development received.
