|Viscosity||As the following viscosity table|
1. Reliable thickener:
As the various types of Cellosize hydroxyethyl cellulose viscosity range is very narrow, as latex paint thickener, can make each batch of latex paint viscosity are consistent, so that the finished product quality is stable and reliable.
2. Easy solution deployment:
Can be a simple mixing device that can be dissolved in hot water or cold water, the solution can be directly added to the latex paint.
3. Excellent compatibility:
Because Cellosize hydroxyethyl cellulose is a non-ionic compound, PH value of 2 to 12 in the pH can be used at ease. But also with all the emulsion and additives have excellent compatibility.
4. Easy construction:
Finished products can be coated with a variety of different types of tools, such as oil brush, roller, cotton gauze and spray method. And there will be no hanging and wrinkles and other phenomena. Have excellent leveling.
5. Coating excellent film:
Since Cellosize hydroxyethyl cellulose does not reduce the surface tension of the latex paint, it does not produce unnecessary foam during the production of the latex paint, and does not cause film formation due to the formation of the foam when the latex paint is applied Resulting in holes and pinholes and other defects.
6. Color stability:
In a variety of different colors and solvent formulations, Cellosize hydroxyethyl cellulose can be coordinated with them, so that the color is more beautiful, the finished product color consistent.
7. Longer shelf life:
As the Cellosize hydroxyethyl cellulose latex paint in the paste more stable, latex paint storage period can be greatly extended, reducing the latex paint and color separation phenomenon. But also in the temperature rise or fall, can maintain a stable viscosity.
