- the density is determined using the liter weight in order to determine whether the products have surface-active properties (tendency to foam), which could then have a negative impact on further testing (assessment of the color surface, etc.).
- the procedure for determining the liter weight is as follows.
- the emulsion paint is stirred with a spatula for 30 s.
- the empty pycnometer (type 290, from Erichsen GmbH & Co. KG, Hemer) is weighed and filled to the brim with the color at room temperature, avoiding air pockets.
- the cover is put on with a slight rotary movement and the substance emerging from the overflow hole is wiped off with a rubber wiper. Then the filled pycnometer is weighed again. The density results from the quotient of the weight difference and the volume.
- the leveling property of the emulsion paint is determined using a leveling doctor blade.
- the paint should usually be easy to spread. This requires a certain viscosity setting and the associated flow behavior.
- a coat of paint that shows brush strokes that are not leveled does not have an optimal flow behavior.
- a glass plate is placed lengthways on the work table.

- the emulsion paint is produced with the thickener to be tested and then mixed with a small amount of a critical pigment.
- the paint is then applied in a defined layer thickness to an uncoated, white cardboard. Subsequent rubbing may result in further digestion of the pigment, recognizable by the increased color intensity at the respective point.

- the white cardboard is placed on the glass plate and the paint is applied with a squeegee. 90 s after the doctor blade is applied at 2 points of the color film (double determination) rubbed in a circular motion with the index finger.

The procedure is as follows.
- Color films are produced with a semi-automatic film puller (film puller type 335/1, Erichsen GmbH & Co. KG, Hemer; squeegee 200 ⁇ m, type 335, Erichsen) to evaluate the color surface and the wash and abrasion resistance.

- Spray tendency The influence of cellulose ether on the spray tendency of a standard
- Emulsion paint For this, a standard emulsion paint is made with the cellulose ether to be tested. A new lambskin roll is wetted with a uniform amount of paint and rolled over an Eternit plate with a Leneta film under it in a precisely defined period of time. The different number of paint splashes, influenced by different cellulose ethers, is assessed visually in comparison to the respective reference sample. The procedure is that the freshly set isoviscos dispersion colors are used. An Eternit plate is placed on a Leneta film at a 90 degree angle. The direction of roll is transverse to the Eternit plate. Approx.
- the evaluation takes place after the paint splashes have completely dried on the Leneta film.
- the strength and number of splashes of paint that occurred during the rolling process are assessed.
- Dispersion paints that contain CMSEC or CMSEC blends are either adjusted (tendency to spray, film hardness) or improved (color gradient, spreadability).
- the colors formulated with CMSEC in particular show improvements in gloss and pigment distribution, which is of particular interest when formulating spot colors.
- the colors 1 and 2 used as standard show curvatures of the surface as well as cracks and detachments at the edge of the glass plates. Such damage cases are not recorded with colors 3, 4 and 5 formulated with CMSEC or CMSEC blends.
- cellulose ethers or cellulose ether mixtures claimed in accordance with the invention are clearly superior to the prior art here, since they make it possible for the user to paint even on particularly critical substrates (for example thin gypsum filler substrates, as is the case when filling with
- Carboxymethylsulfoethyl cellulose ethers are used as thickeners for dispersion-bound building material formulations and have the advantage that they do not reduce the gloss, especially in systems with a high binder content or dispersion content, i.e. low pigment volume concentration (PVC), an excellent pigment distribution ("rub-out” ) and at the same time can also be applied without any problems on particularly critical substrates, such as gypsum filler substrates or under critical drying or curing conditions.
