example

[0301] The following non-limiting examples are provided to further illustrate the compositions and methods provided herein. Unless indicated otherwise, the percentages are percentages by weight relative to the total mass of the composition and add up in each case to 100% by weight.

[0302] testing method :

[0303] Static Water Contact Angle Measurement [W.C.A.]

[0304] Static water contact angle measurements were performed on dried (treated) samples using deionized water available from Millipore Corporation. The contact angle analyzer used was a Video Contact Angle Analyzer available under the trade designation VCA Optima (AST Products Inc.). Static contact angles were measured on sessile droplets (1 μL) at 30 seconds after deposition. The reported values ​​are the mean of at least 4 individual measurements.

[0305] Transmittance measurement :

[0306] Samples were tested for light transmission (T) and haze (H) using a BYK Gardner Haze-Gard Plus instrument (BYK ...

example 1 and example 2 and comparative example C-1 and comparative example C-2

[0337] In Examples 1 and 2, glass test panels were treated with 5% by weight aqueous dispersions of acidified SIL-3 containing various amounts of Z silane as given in Table 1 according to the general method. Comparative Example C-1 was made with a glass test panel treated with a 5 wt % aqueous dispersion of acidified SIL-3, while Comparative Example C-2 was made with a glass test panel treated with a 5 wt % aqueous dispersion of Z silane. Hard water stains were produced according to the methods outlined above. The test panels were evaluated for their transmittance. All test results are listed in Table 1.

example 3 and comparative example C-3

[0341] Example 3 and Comparative Example C-3 were made in the same manner, except that different silica nanoparticles and different sulfonated silanes were used, as indicated in Table 2. The coating composition had a total solids content of 5% by weight. Hard water stains were produced according to the general method outlined above. The test panels were evaluated for their transmittance. The test results are listed in Table 2.

Abstract

This invention relates to coating compositions useful for the prevention and / or removal of limescale and / or soap scum. More specifically, the present invention is directed to a coating composition comprising acidified silica nanoparticles and a sulfonated polymer. The present invention is further directed to a method for the prevention and / or removal of limescale and / or soap scum from the surface of a substrate. The invention also relates to the use of such a coating composition for the prevention and / or removal of limescale and / or soap scum from the surface of a substrate.

Description

technical field [0001] The present invention relates to coating compositions useful for preventing and / or removing limescale and / or soap scum. More specifically, the present invention relates to coating compositions comprising acidified silica nanoparticles and sulfonated polymers. The present invention also relates to methods for preventing and / or removing scale and / or soap scum from substrate surfaces. The invention furthermore relates to the use of such coating compositions for the prevention and / or removal of scale and / or soap scum from substrate surfaces. Background technique [0002] Many efforts have been made to develop compositions that can be applied to substrates to provide a beneficial protective layer having desirable properties such as one or more of ease of cleaning, stain resistance, long-lasting performance, hard water stain deposition inhibition, etc. . Many compositions developed for such applications contain materials such as volatile organic solvents,...
