Abstract

s floor coating remover composition with abrasive and reduced slip properties under foot. Solid plastic, natural stone or other inorganic or organic grit is incorporated into a floor coating removing formulation to provide a coefficient of friction so that slippage under foot during use is reduced. In the instance of the presence of natural stone grit or other inorganic grit, a stabilizer may be employed to keep the grit in suspension.

Mixing & Usage Procedure
The anti-slip additive (grit) can be mixed into the above Formulas 1 and 2 and used in one of the following ways:
1. Premixed into the stripper formulation, with or without a stabilizing additive (thickener). The stripper is then mixed with water immediately prior to use and applied onto the floor. Occasional gentle stirring may be needed to redisperse the grit. Stripping of the floor finish is continued in the usual way.
2. Floor finish stripper is mixed with water and applied onto the floor in the usual way. Grit is broadcast into the wet stripper formulation, either by hand or using a piece of equipment. Stripping of the floor finish is continued in the usual way.
3. Floor finish stripper is mixed with water. Grit is added to the stripper formulation and stirred lightly with the mop or other application device. This is applied onto the floor in the usual way, gently stirring occasionally, as needed to redisperse the grit. Stripping of the floor finish is continued in the usual way.
4. A thickened floor finish stripper formulation as set forth in Formula 2 is mixed with water. Grit is added to the stripper solution & stirred lightly with the mop or other application device. This is applied onto the floor in the usual way. Stripping of the floor finish is continued in the usual way. 5. Floor finish stripper is mixed with water. A special blend of a grit and a thickener is added to the stripper solution & stirred with the mop or other application device. This is applied onto the floor in the usual way. Stripping of the floor finish is continued in the usual way. The special blend of grit and thickener is 61.5 parts by weight of Acrysol 820 and 38.5 parts by weight of an anti-slip grit such as ResNSand 34SG. The preferred approaches are 1, 3 or 4.
Several formulas were evaluated for wet coefficient of friction. Testing was carried out as follows:
Four coats of Premia floor finish available from S. C. Johnson Commercial Markets, Inc., Sturtevant, Wisconsin, were applied to vinyl composition tile floor. One part of the Bravo floor finish remover available from S. C. Johnson Commercial Markets, Inc. was mixed with four parts of water (diluted in this way, this stripper is referred to as Bravo in subsequent tables). ResNSand grit was incorporated therein. The ResNSand products used in the following Tables are available from American Fillers & Abrasives Inc., Bangor, Michigan. The chemical compositions of the polymeric grits tested are as follows:
ResNSand 34S: Polyallyl diglycol carbonate ResNSand 34H: Styrene acrylonitrile ResNSand 87P: Cross linked polyvinyl chloride ResNSand 69N: Cross linked urea formaldehyde The second letter with the number indicates particle size.
The Vydyne product is nylon available from Solutia Inc., St. Louis, Missouri. Using a Brungraber MK2 slip tester each of the samples was tested for its wet coefficient of friction (CoF), with different mesh sizes. The results are given below in Table III.
TABLE III [
Example Description Amounts Grit Size Wet CoF
1. Bravo 720 grams 20-30 Mesh 0.15-0.16 ResNSand 34SD 80 grams
2. Bravo 720 grams 30-40 Mesh 0.17-0.19 ResNSand 34SE 80 grams
3. Bravo 720 grams 60-80 Mesh 0.21-0.25 ResNSand 34SF 80 grams

6. Bravo 720 grams 325 Mesh 0.27-0.29 ResNSand 34SJ 80 grams
7. Bravo No Grit 0.03-0.05 NO GRIT
Further evaluation of wet coefficient of friction of grit/stripper mixtures with ResNSand 34SG are shown in Table IV. Three coats of Premia floor finish were applied to vinyl composition tile floor and allowed to dry for two weeks. The grit/stripper blends were shaken and poured onto the floor. These blends were of six types.
Using the Brungraber MK2 slip tester each of the samples was tested for its wet coefficient of friction, (CoF), with the results being given below.

Example Description Amounts Grit Size Wet CoF
8. Bravo 999 grams 100 Mesh 0.05-0.07 ResNSand 34SG 1 gram

13. Bravo 700 grams 100 Mesh 0.19-0.21 ResNSand 34SG 300 grams
14. Bravo 1000 grams N/A 0.03 NO GRIT
These results are plotted in the bar graph shown in Figure 1. They show that a 10% grit level is an optimum amount.
Still further evaluations of wet coefficient of friction of grit/stripper mixtures were carried out as shown in TABLE V.
Three coats of Premia floor finish were applied to vinyl composition tile floor. The next day the grit/stripper mixtures were agitated and poured onto the floor. Eight grits with different chemical composition and particle size were mixed with Formula 1. Using the Brungraber MK 2 slip tester, each of the samples was tested for its wet coefficient of friction (CoF) with the results being given below. TABLE V

Observations on Data i:
Regardless of the chemical composition of the grit or its particle size, CoF values obtained were higher than that of a stripper formulation containing no grit. CoF values obtained with the 20% grit consistently exceeded those obtained with 3% grit.
It will thus be seen that there is now provided an anti-slip floor coating remover composition. While the composition is described in conjunction with two basic formulas, it can be employed with any floor finish remover which is water soluble including those which are solvent based or water dispersible. While many types of grit particles have been evaluated in the anti-slip stripper composition of this invention, those particles which are somewhat angular in nature are prefeπed. It is theorized that the angular nature is important in the effectiveness. Other solid polymeric grits or inorganic grits will perform equally effectively. Although any chemical type of solid grit can be used, the styrene acrylonitrile and cross-linked polyvinyl chloride are preferred as they have been shown to abrade the coating film in the stripping process, while effecting minimal damage to the vinyl composition tile underneath. Other solid grit particles such as a solid organic grit in the form of a cellulosic material available from American Fillers and Abrasives Inc., which also provide an anti-slip benefit, whether or not they abrade tile, can also be employed in this invention.
Any level of solid grit has been shown to have a positive effect on the anti-slip attributes between 0.1% and 30%, based on total diluted stripper. A level of 10% appears to be optimal. Additional testing showed that 50% grit also provided the same benefit, but that handling and foam of the stripper/grit blend was compromised adversely. With regard to mesh sizes, it has been shown that particles in the range of 12 US mesh to 325 US mesh have a positive effect on the wet slip resistance. Particles larger than 12 US mesh as well as those less than 325 US are also effective.
Other variations and modifications of this invention will be obvious to those skilled in this art. This invention is not to be limited except as set forth in the following claims.
