Coating Innovations: Coatings Go Green

May 1, 2012

Bayer MaterialScience introduces UV-curing coatings for the cost-efficient and sustainable coating of furniture and parquet flooring.

In recent years, waterborne UV-curing coatings have gained an increasing market share. For example, office furniture manufacturers now advertise that their products are coated through a low-emissions, environmentally compatible process. Such requirements can be met particularly cost effectively with coatings based on raw materials Bayer MaterialScience’s Bayhydrol® UV range, which cure in seconds under UV light. The solvent-free waterborne dispersion Bayhydrol® UV XP 2775 is used 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 is a new UV-curing, cationic urethane acrylate emulsion that can provide fast drying, reportedly making it an 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 by outstanding adhesion on problematic woods and the suppression of staining wood constituents such as tannins. The primers also accentuate the grain of the wood.

For the typical uses for parquet flooring, it is important that surfaces be extremely abrasion- and chemical-resistant. UV-curing clearcoats formulated with 100% solids systems from the Desmolux® line or with waterborne coatings based on Bayhydrol UV can satisfy these requirements. The rapid UV curing can also ensure high speed and efficiency in the production of prefabricated parquet.

In addition to industrial applications, it is now also possible to renovate floors on-site using portable devices to cure the newly applied coating. Thanks to the UV drying, the floor can be walked on again shortly after coating. (Previously, waiting periods of one to three days were required before floors could be used.)
