Applicators want a product with chemical and stain resistance, low odor, long-term performance, ease of use and concrete penetration. Bayer developed a two-component (2K), polyurethane waterborne technology for sealers that offers a number of advantages over currently available concrete sealer products, including better ease of use; improved durability; low odor; increased service life; and ultra-low volatile organic compounds (below 15 grams per liter).
Steven Reinstadtler, construction marketing manager for coatings, Bayer MaterialScience LLC, says that this 2K, polyurethane waterborne technology guards against stains as it is resistant to a wide range of household and industrial chemicals or staining agents.
“There are three types of flooring—decorative stained, diamond polished and color-pigmented concrete—that are becoming popular and sustainable flooring options and could use a sealer,” said Reinstadtler. “These types of floors are increasingly being installed in higher visibility venues where aesthetics matter, and the 2K, polyurethane waterborne technology for sealers from Bayer protects the flooring while also preserving its aesthetics.”
The various types of stained and polished flooring on which the sealer would be applied are often found in commercial and retail spaces, such as hotel lobbies and restaurants. The technology is primarily applied to indoor surfaces, but is also appropriate for outdoor applications.
