Waterborne UV-curing PU dispersions for environmentally friendly and resilient coatings on PVC and linoleum flooring
Driven by the need for more quality, efficiency and environment friendliness, leading manufacturers of resilient PVC and linoleum flooring are now choosing the Bayhydrol® UV range of waterborne UV-curing polyurethane dispersions (PUD) for their top qualities. Because besides being resilient and flexible, these industrial flooring coatings are good for the environment.
Waterborne benefits
Our UV-curing waterborne technology has numerous advantages. In contrast to UV solvent-borne technology it is free of reactive diluents, tack-free before UV and displays no shrinkage, needs less photo initiator, reduces wastage through overspray recycling and delivers easier matting, flexibilization and pigmentation. UV waterborne technology is the fastest-curing waterborne coating technology, has the highest crosslink density, offers close to 0% VOC and 100% overspray recycling, and allows postforming through stepwise curing. These advantages make this technology particularly suitable for pigmented, matt and effect coatings, rheological control during application, postforming – and of course resilient flooring coatings.
Meeting market needs
Quality in industrial flooring coatings means they need to look good, feel right, have excellent mechanical properties and high stain resistance (e.g. against household chemicals, felt-pens and comestibles like mustard and red wine), easy matting and the possibility of pre-UV embossing. Efficiency is mainly about cost and processing efficiency, and the key environmental factors are emissions and energy consumption. Bayhydrol® UV binder material makes high-performance UV-curing coatings possible for a number of applications – and performs well in quality, efficiency and environmental terms. Bayhydrol® UV XP 2661 and Bayhydrol® UV XP 2721 are the main Bayhydrol® UV products for PVC-flooring substrates. They are suitable for clear coats on semi-gloss or matt surfaces, have good adhesion and high abrasion, chemical and stain resistance properties and display high UV reactivity. Whereas XP 2661 has its strength in stain resistance, Bayhydrol® UV XP 2721 brings the benefits of improved hardness and physical drying (tack-free before UV), which allows improved embossing of the coated flooring before UV-curing. Both XP 2661 and XP 2721 can easily be combined with the other products from the Bayhydrol® UV product portfolio to achieve different property profiles. The Bayhydrol® UV range proves that waterborne technology not only matches the performance of solvent-borne products but in some cases exceeds it. Nobody doubts that water is green, but just how good this UV waterborne technology’s performance is might well surprise some.
