Field-applied, Uv-curable Coatingsfor Concrete Flooring

摘要

the flatness of the floor were shown to be more critical for UV coatings. The methods for applying UV coatings were likewise determined to mimic those of other technologies, and important parameters involving the coating thickness and uniformity were identified. The need to achieve acceptable cure by using equipment that delivers the appropriate irradiance and energy density and by controlling the speed to deliver the proper energy were also discussed. Both undercure and overcure conditions should be avoided. Finally, the need to be able to evaluate concrete floor coatings for suitability for use was discussed. European standard EN1504-2 was outlined and suggested as proper methodology for determining suitability for use. The information discussed above shows that despite the many challenges associated with bringing UV technology to the world of concrete coatings, transformations have successfully occurred. The high cure speeds of UV technology allow a floor contractor to apply coatings to areas they could never have considered before due to the long time required before they could be returned to service.
