Problems solved by technology

[0006] However, since current UV-curable floor coatings are designed to be cured by light in the UVA range of 315-400nm emitted by common UV lamps, known UV-curable floor coatings cannot be cured by UVV radiation and thus cannot obtain UVV Advantages realized by LED

Embodiment 1 to 24

[0058] As the coating composition to be cured according to the exemplary embodiment, formulation compositions shown in Tables 1B, 2A, and 2B were prepared and cured using UVV LEDs using urethane acrylate as a resin. For each case, all qualified components were added to small brown glass jars and mixed with high speed agitation until the photoinitiator was dissolved. Examples 1 to 5 and 11 to 24 were mixed at 130°F, while Examples 6 to 10 were mixed at room temperature. Compounds identified in the table as "Duracote 7" refer to acrylate urethanes of the type disclosed in US Patent No. 5,719,227, which is incorporated herein by reference. The "bio-based acrylate polyurethane" resin is similar to Duracote 7, except that it is based on a castor oil polyol starting material, as described in US Publication No. 2009 / 0275674, which is also incorporated herein by reference.

Embodiment 25 to 31

[0084] The formulations shown in Table 6, prepared as coating compositions and cured using UVV LEDs, include Examples 30 and 31, which demonstrate green embodiments where the compositions are bio-based polyol crosslinkable compounds (Table Polyol-5) in 1A, used in combination with epoxy resin. For each case, all qualified components were added to a small brown glass jar and mixed with high speed agitation at 130°F until the photoinitiator was dissolved. At this point, add matting agent slowly and stir at high rpm for at least 15 minutes. Thereafter, the viscosity of the sample was measured.

[0087] Examples 25 to 31 were also applied to the same type of biobased tile as previously described, which was 1 mil thick, and was likewise cured using a Phoseon Technology WCRX Starfire LED Quad, which had a specific wavelength of 380 to 420 nanometers, using 2W / cm 2 Water-cooled UVV LED, the unit curing area is 0.75 inches by 12 inches. The height of the LE...

Abstract

A floor covering includes a wear layer including a resin and a photoinitiator in which the composition of the wear layer is curable by radiation having the strongest wavelength in the UW range of 400 to 450 nm. The gloss of the wear layer can be controlled by controlling the amount of flatting agent in the composition applied to the surface, the amount of power applied to the surface coated with the composition or the temperature of the surface coated with the composition when the coated surface is subjected to the UW radiation.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application Serial No. 61 / 173,996, filed April 30, 2009, which is hereby incorporated by reference in its entirety. field of invention [0003] The present invention relates to radiation curable compositions for coating substrates, and more particularly to light emitting diode (LED) curable coatings in the ultraviolet (UV) V spectrum for flooring and other applications. Background of the invention [0004] Radiation curable coatings, such as UV curable coatings, are used on various types of substrates to enhance their durability and finish. These radiation curable coatings are typically mixtures of resins, oligomers, and monomers that can be cured by radiation after application to a substrate. The radiation curing polymerizes and / or crosslinks resins, monomers, and oligomers to produce high-gloss or low-gloss coatings with desired properties, including abrasion and chemica...
