Non-slip masking product, and methods
View Patent ↗A masking product having an exposed non-slip surface. In some embodiments, the masking product has two non-slip surfaces, on opposite sides of the paper. The non-slip surface exposed surfaces having an increased coefficient of friction to inhibit the movement (e.g., slipping) of items present on the non-slip surface.
1. A method of protecting a surface to be walked on, comprising:
placing a masking product having a first non-slip coating and a second non-slip coating over a surface to be walked on so that the first non-slip coating is positioned upwardly facing, the first non-slip coating and a second non-slip coating each having a horizontal plane coefficient of friction of at least about 0.4 as determined by TAPPI T816 and being non-tacky as determined by a Vertical Wall Test wherein the non-slip coating on the masking product will not stick or adhere to a vertical stainless steel surface at room temperature;
(i) the masking product comprising a paper sheet having a basis weight of about 5 to about 100 pounds per 1,000 square feet;
(ii) the first non-slip coating provided from an encapsulated material activated by bursting the encapsulated material;
(iii) the first non-slip coating being provided on a first side of a paper sheet and the second non-slip coating being provided on a second, opposite, side of the paper sheet; and
walking on the masking product.
2. The method of claim 1 wherein the masking product is placed in close proximity to a surface to be painted.
3. The method of claim 1 , wherein the paper sheet has a basis weight of about 20 to about 100 pounds per 1000 square feet.
4. The method of claim 1 , wherein the first non-slip coating has a coating weight of at least about 1 pound per 1000 square feet.
5. The method of claim 1 , wherein the first non-slip coating has a coating weight of at least about 2 pounds per 1000 square feet.
6. The method of claim 1 , wherein the second non-slip coating is the same as the first non-slip coating.
7. The method of claim 1 wherein the first non-slip coating has a horizontal plane coefficient of friction of at least about 1 as determined by TAPPI T816.
8. The method of claim 1 , wherein the first non-slip coating has a horizontal plane coefficient of friction of at least about 2 as determined by TAPPI T816.
9. The method of claim 1 , wherein the first non-slip coating has an inclined plane coefficient of friction of at least about 22° as determined by TAPPI T815.
10. The method of claim 1 , wherein the first non-slip coating has an inclined plane coefficient of friction of at least about 45° as determined by TAPPI T815.
11. The method of claim 1 , wherein the first non-slip coating has an inclined plane coefficient of friction of at least about 70° as determined by TAPPI T815.
12. The method of claim 1 , wherein the first non-slip coating is free of abrasive materials.
13. The method of claim 1 , wherein the first non-slip coating is free of aluminum oxide, silicon carbide, and garnet.
14. The method of claim 1 , further comprising securing the masking product by applying strips of masking tape along edges of the masking product.
15. A method of protecting a surface to be walked on, comprising:
placing a masking product having a non-slip coating over a surface to be walked on so that the non-slip coating is positioned upwardly facing, the non-slip coating having a horizontal plane coefficient of friction of at least about 0.4 as determined by TAPPI T816 and being non-tacky as determined by a Vertical Wall Test wherein the non-slip coating on the masking product will not stick or adhere to a vertical stainless steel surface at room temperature;
(i) the masking product comprising a paper sheet having a basis weight of about 5 to about 100 pounds per 1,000 square feet; and
(ii) the non-slip coating provided from an encapsulated material activated by bursting the encapsulated material; and
(iii) the masking product includes an adhesive coating on the paper sheet opposite the non-slip coating; wherein the step of placing comprises adhering the adhesive coating to the surface to be walked on; and
walking on the masking product.
16. The method of claim 15 , wherein the masking product further comprises a release liner over the adhesive coating prior to the step of placing.
17. The method of claim 15 , wherein the adhesive coating includes no abrasive particles.
18. The method of claim 15 , wherein the adhesive coating comprises a pressure sensitive adhesive.
