Ammonium polycarboxylate Dispersant WAS-290B for dispersing Titanium dioxide and calcium carbonate
Main ingredient: Polycarboxylate ammonium salt
Physical and chemical indicators: Appearance: yellow transparent liquid
pH value: 9.5-10.5
Viscosity: 350-850 mPa.s
Ionicity: negative
Solid content: ≥40%
Performance characteristics and uses:
1. Dispersant WAS-290B is suitable for dispersing pigments and fillers such as titanium dioxide and calcium carbonate.
2. This product has excellent dispersing effect on various inorganic powders such as titanium dioxide, talc, calcium carbonate, iron oxide, etc. It sharply reduces the viscosity of the grinding material, shortens the grinding time, stabilizes the pigment dispersion system, and helps prevent organic pigments. flocculation, reducing the tendency of floating color and blooming.
3. Dispersant WAS-290B can be used alone or together with other types of dispersants. It can be used in various water-based industrial paints and pigment concentrates.
4. This product can be adsorbed on the surface of various tiny particles and generate electrostatic repulsion to disperse them, avoiding sedimentation and coarsening. Mainly used as additives in electronic ceramics, paper industry, alumina ceramics, household ceramics, magnetic materials and other industries.
5. Add a small amount of this product to obtain a low-viscosity and high-concentration color paste, and at the same time the paste
Dispersant WAS-290B/10 Instructions
The aging stability of materials and coatings is excellent.
6. Dispersant WAS-290B/10 also has a good dispersing effect on phthalocyanine blue and phthalocyanine green.
Usage and dosage:
Usually, the dispersant WAS-290B is first added to the water, mixed thoroughly, and then the pigment is added under stirring.
When used in various inorganic powders such as titanium dioxide, talc, calcium carbonate, iron oxide, etc., the addition amount of dispersant WAS-290B is 0.3-2% of the total pigment; when used in phthalocyanine blue and phthalocyanine green, dispersing agent WAS-290B Additive amount of WAS-290B is 10-15% of the total amount of pigment.
safety:
This product is uniform, stable and non-volatile. Non-flammable, explosive, can be transported by usual methods.
Package:
50KG or 130KG plastic drum.
