In the past five or so years, commercial UV curing has moved out of the factory and into the field, with numerous improvements in UV curing equipment pushing the transformation of this technology into the area that one calls Field Applied UV Curable Coatings.
In these field applied UV curing applications, the substrate to be coated is stationary while the UV curing equipment is moved over the surface or substrate for curing. UV curable field applied coatings are being developed in an effort to address some of the shortcomings of commercially available coating systems on the market. The benefits of using UV cured field applied coatings as compared to conventional coating technologies for these different surfaces are numerous and are similar to factory applied floor coatings: increased productivity and performance. In addition, the immediate cure aspect provides cost savings to the end user through immediate use, and added benefits of quality, since the finish will not be damaged once it is cured.
Today, these field applied or on site floor coatings for wood, vinyl, tile, and concrete are all in some phase of commercialization. This paper will highlight the latest resin and coating developments to address some of the challenges identified during the introduction of UV technology in field applied flooring.
