[Introduction]
Alkali-swelling non-associative thickener ASE-60
ASE-60 is a cross-linked polymer emulsion thickener containing an acidic group. When it is neutralized with water and diluted with a base, the latex particles rapidly expand. Under such conditions, the emulsion will become clear and Very sticky.
ASE-60 can effectively improve the low shear viscosity and make the coating system have higher pseudoplasticity. The coating prepared with ASE-60 as the main thickener has a higher yield value and gel structure. This structure will be exhibited after the shear force disappears. Therefore, ASE-60 is suitable for formulating coatings with moderate three-dimensional effect. .
ASE-60 also reduces roll splattering compared to high molecular weight cellulosic thickeners. Because it does not contain cellulose, its antimicrobial and enzymatic invasive ability is high, so the viscosity of the coating can be stable for a long time.
[Features and advantages of ASE-60]
*Excellent texture retention
*Excellent sag resistance
* Improve splash resistance
*Antimicrobial and enzyme
[Physical properties]
Appearance: milky white liquid
Solid content: 28%
Density: 1.05
Viscosity (centipoise) <50
pH 2.1-3.5
[Add method]
1. The pH of the coating was adjusted with ammonia to a temperature of 8.0-9.0.
2. Dilute ASE-60 water in a 1:1 ratio.
3. The diluted ASE-60 was slowly added under low-speed agitation.
4. The viscosity of the coating was measured while stirring, and after the desired viscosity was reached, the addition of the thickener was stopped.
