Revêtements -- Propriétés mécaniquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Water-based coatings made from WB UV resins, acrylic emulsions, and polyurethane dispersions all are good candidates for industrial wood coatings. They have very good chemical resistance and mechanical propertie. They can be formulated at low VOCs and have low toxicity. They are viable alternatives to solvent-based chemistries.

Souplesse (mécanique)Index. décimale : 667.9 Revêtements et enduits Résumé : 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 waterborne systems. However, most of the current waterborne OMUs either still contain N-Methyl-2-pyrrolidone (NMP), or the VOC is still relatively high at 135–250 g/L, while the nonvolatile (NV) content is relatively low at 32–38% and thus requires multiple coats to achieve performance properties.1 This article demonstrates a recent breakthrough in the development of a novel NMP-free waterborne OMU with a VOC <100 g/L and a high 45% NV content that maintains the exceptional performance properties of traditional solventborne and waterborne 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. Note de contenu : - Dry time
