Résumé : |
Demand for high-performing, water-based coatings continues to be the trend throughout the many coatings market segments. Wood flooring, cabinetry, and furniture coatings segments are a major component of this movement. To support this transition, development of innovative solutions is required to provide improved coatings performance. End users are seeking increased durability and lower environmental impact, which comes with water-based technology. Improved scratch resistance will improve the long-lasting aesthetics and protection that wood coatings provide. A novel, easy-to-use approach to improve scratch resistance in water-based wood coatings has been demonstrated in multiple resin technologies. Performance testing of improved scratch resistance while maintaining good film properties will be presented in a water-based, ultraviolet (UV)-curable system that exceeds performance of current market offerings. |
