This Small Business Innovation Research Phase II project is designed to develop and optimize a prototype environmentally friendly isocyanate-free solvent-free UV curable hybrid resin system demonstrated in EPA SBIR Phase I research to have properties suitable for commercial industrial applications such as automobile refinishing, floor coatings, and aircraft coatings. Properties of the proprietary hybrid resin system are significantly improved over those of conventional UV systems. UV cure provides an immediate track-free surface and significant property development, allowing materials to be handled for secondary operations. Hybrid cure continues at ambient conditions following UV exposure for reduced molecular stress and the unusual combination of improved adhesion, flexibility, and hardness. This dual cure system is user-friendly and allows for the convenient sanding of primer coatings before surface hardness increases to an extent that makes sanding operations unmanageable. Light Curable Coatings is a technology leader for solvent-free environmentally compliant coating systems, with proprietary technology to rapidly cure heavily pigmented coatings with UV light, including low gloss camouflage color UV coating systems. Phase II research will optimize fully formulated isocyanate-free solvent-free UV curable hybrid resin systems incorporating pigments and chrome-free corrosion inhibitors, with testing according to military aerospace primer and topcoat specifications MIL-PRF-23377 and MIL-PRF-85285.
