Bayer MaterialScience is introducing new developments in UV-curing coatings. The technology is characterized by high productivity and environmental compatibility, and has proven effective in numerous applications for polyurethane coatings, the company said. The focus is on the industrial coating of wood, furniture and parquet flooring. A new technology for the on-site use of parquet coatings is also being introduced.

One technology is the solvent-free waterborne dispersion Bayhydrol UV XP 2775 for white-pigmented, UV-curing coatings and topcoats. The surface is characterized by excellent chemical and stain resistance, even with a high pigment content. Coatings formulated to contain this product also have good gloss and outstanding hardness, making them suitable for use in wood and furniture finishing, including for kitchen cabinetry.

Bayhydrol UV 2792 XP, a new UV-curing, cationic urethane acrylate emulsion, provides for fast drying and thus the efficient industrial basecoating of furniture and parquet flooring. Primers formulated with this product offer very good chemical and stain resistance in addition to high pendulum hardness. However, this cationic emulsion is characterized in particular by adhesion on problematic woods and the suppression of staining wood constituents such as tannins. The primers also accentuate the grain of the wood.
