Session 2: Wood Coatings
Vegetable oil modified urethane (OMU) has been widely used in wood flooring applications for many decades. Due to tightening Volatile Organic Compound (VOC) regulations in recent years, the market has been slowly shifting towards water-borne systems. However, most of the current water-borne OMUs either still contain N-Methyl-2-pyrrolidone (NMP), or the VOC is still relatively high at 135-250 g/L while the non-volatile (NV) content is relatively low at 32-38% and thus require multiple coats to achieve performance properties. In this paper we will demonstrate our most recent breakthrough in the development of a novel NMP free water-borne OMU with a VOC <100 g/L and a high 45% NV content that maintains the exceptional performance properties of traditional solvent-borne and water-borne OMUs in the market. Its potential applications include but are not limited to high performance clear wood floor coatings, conformal coatings, air dry and force cure coatings.
