Embodiment 1

[0075] Five (5) exemplary coatings of the present invention are described in Table 1 (below). These coatings are made by conventional methods readily understood by those skilled in the art.

[0077]

[0078]

Embodiment 2

[0080] The ability of the coatings of the present invention to resist heel abrasion was evaluated against an acrylate coating that did not contain the combination of ingredients provided by the embodiments of the present invention. Specifically, the coatings were applied to substrates and evaluated for ease of abrasion and ease of mar removal. The data described in Table 2 (below) demonstrates that the inventive coatings (I-V) provided acceptable levels of heel abrasion resistance, whereas the comparative acrylate coating (CI-CV) not containing the inventive combination of ingredients did not. . "P" indicates an acceptable level of heel scuff resistance, while "F" indicates an unacceptable level of heel scuff resistance. Additionally, it is worth noting that the comparative acrylate coatings are much more prone to abrasion than the inventive coatings.

[0082]

Embodiment 3

[0084] The ability of the coatings of the invention to resist abrasion was evaluated against an acrylate coating that did not contain the combination of ingredients provided by the embodiments of the invention. Specifically, the coatings were applied to substrates and each coated substrate was exposed to 320 grit sandpaper in a Byk Gardner Abrasion Tester for thirty (30) cycles . Gloss measurements were taken before and after completion of 30 cycles. Gloss readings before and after exposure were compared and percent gloss retention was calculated.

[0085] The data described in Table 3 (below) demonstrates that inventive coatings (I-V) provide acceptable levels of abrasion / scratch resistance compared to comparative acrylate coatings (CI- CV) not provided.

Abstract

Described herein are UV curable coatings comprising: an acrylate component, a photoinitiator, an amine synergist, and an abrasive; and methods of making and using the same.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application Serial No. 61 / 695,347, filed August 31, 2012, entitled "UV Curable Coating," the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates to radiation curable compositions for coating substrates, and more particularly to UV curable coatings for flooring and other applications. Background technique [0004] Radiation-curable coatings, such as ultraviolet (UV) curable coatings, are applied to a variety of substrates to enhance their durability and finish. These radiation curable coatings are typically mixtures of resins, including oligomers and monomers, that are radiation cured after application to the substrate. The radiation curing polymerizes and / or crosslinks the resin to produce high or low gloss coatings. Radiation curable coatings are often referred to as topcoats or wear coats ...
