Special Dispersing Agent LDC- 40

(For Wet Grinding Calcium Carbonate)

Product Description:

This product is a kind of modifying fork chain and low molecular weight Sodium Polyacrylate organic dispersing agent, it can help to improve the dispersion and stability of particle, moreover, to improve the rheology and liquidity of emulsion or serum, it has a very good effect on grinding and dispersing, if used by grinder, it can pass mechanical shearing force to calcium carbonate particle to increase the efficiency of grinding,increase the production,or under the same wet grinding circumstances, thinner calcium carbonate particle can be got. LDC 40 have many advantages, such as lowering the viscosity of calcium carbonate serum, preventing sedimentation,agglutination or agglomeration of calcium carbonate particle and so on, it has a lower viscosity of calcium carbonate serum ,good invariability of serum, serum can get a better liquidity under such high shearing force.

Product Properties:

1. Good wet grinding dispersivity.

2. Prevent agglutination,sedimentation or agglomeration of calcium carbonate particle.

3. Low viscosity and good invariability for serum.

4. Can be made for high solid coatings.

5. Easy to operate and weigh.

6. Promote lustrousness and invariability of viscosity.

7. Save energy.
