Waterborne UV-cure resins for PU coatings help to reduce downtime

26-Feb-09

Bayer MaterialScience LLC's one-component waterborne ultraviolet (UV) resins, including Bayhydrol® UV resin, enable polyurethane coatings for floors that utilize the fastest cure technology for on-site flooring applications. "This coating is designed for applications where downtime must be kept to a minimum, such as hospital operating room floors or commercial kitchens," said Ed Squiller, director of business development, Corrosion and Construction Coatings, NAFTA, Bayer MaterialScience LLC. "As an added benefit, the one-component technology eliminates mistakes that can be made during the mixing process, which is required with two-component coatings." Applying UV-cured polyurethane coatings on-site is a newer application for this technology, which traditionally has been used to manufacture flooring typically used for in-shop coating applications, according to Squiller. Contractors can use a variety of methods for UV curing, including exposure to natural sunlight, full-spectrum UV bulbs and QUV-A bulbs. In addition to offering a fast turnaround, UV-curable polyurethane coatings, the company claims, are odorless, UV light stable for resistance to weathering, non-yellowing, abrasion resistant and chemical resistant.
