preparation example Construction

[0054] The present invention also provides a method of preparing a coating comprising applying a coating composition to a substrate and allowing the coating to harden (for example by exposing the coating composition to radiation such as ultraviolet or visible light). The present invention also provides coatings prepared or producible from the coating compositions described herein. For example, coatings of the invention can be prepared by a process comprising applying the coating composition to a substrate and allowing the coating composition to harden (eg, by exposing the coating composition to radiation such as ultraviolet or visible light).

[0055] A preferred coating is obtained by exposing the coating to a -3 nm to 800nm ​​radiation to cure. More preferably, the coating composition of the present invention is exposed to ultraviolet or visible light in the range of 200nm to 800nm. The coating compositions of the present invention may also be cured thermally or by other f...

Embodiment 1

[0087] Embodiment 1: Preparation of urethane coating composition

[0088] The metal particles and matting agents listed in Table 1 below were dispersed in a mixer / disperser such as those available from Morehouse Cowles, Chino, CA or from Hockmeyer Equipment Corp., Elizabeth City, NC. The remaining ingredients are then dispersed in a mixer to form a coating composition.

[0089] Table 1

[0090]

[0091] The coating composition was rolled onto wood floor samples and then cured with UV light to form the coating.

[0092] After curing was complete, the coating was marked with a permanent marker available from Sanford LP, Oak Brook, IL under the trade name Sharpie. After the ink from the marker has dried, wipe the marker with a white cotton rag. Start by rubbing lightly and then more vigorously to assess whether the ink can be removed completely without affecting the gloss of the coating or removing the coating. If the shading or dye remains after wiping with a cotton cloth...

Embodiment 2

[0094] The preparation of embodiment 2-epoxy resin coating composition

[0095] Using the procedure set forth in Example 1 above, an epoxy coating composition was prepared using the ingredients in Table 2 below.

[0096] After curing was complete, the coating was marked with a permanent marker available from Sanford LP, Oak Brook, IL under the trade name Sharpie. After the ink from the marker dries, wipe the marker with a white cotton rag. Start by rubbing lightly and then more vigorously to assess whether the ink can be removed completely without affecting the gloss of the coating or removing the coating. If the shading or dye remains after wiping with a cotton cloth, use rubbing alcohol and / or nail polish remover to remove any remaining markings.

[0097] The ink marks can all be completely removed with the coating still intact.

Abstract

A coating composition including a functionalized resin selected from at least one of polyurethanes, epoxies, polyamides, chlorinated polyolefins, acrylics, polyesters, or mixtures or copolymers thereof, wherein the resins comprises at least one of (meth)acryl or acetoacetyl functionality; a (meth)acryl functional compound; and a functionalized silicone compound.

Description

Background technique [0001] Coatings applied to some substrates such as pre-finished wood floors, cabinets, and furniture can be permanently stained by inks and stains in pens, markers, and the like. Once the finish has been damaged by ink, the ink stains can only be removed by using a strong solvent, rubbing with sandpaper, or completely removing the paint layer (or the entire paint layer) in the marked area. In many cases, even if the ink is partially removed by rubbing or solvents, the finish may be permanently damaged, stained or marked due to the cleaning process. Contents of the invention [0002] In general, the present disclosure relates to coating compositions that can be cured to provide coatings with enhanced resistance to staining and marking by inks and colorants in pens, markers, and the like, and to making Coating composition and method of coating. [0003] In one embodiment, the present disclosure relates to a coating composition comprising: at least one se...
