New product development success!! JH-627 paper coating thickener

JH-627 paper coating thickener can completely replace CMC, with better thickening water retention performance, smooth gloss, easy to operate, reduce costs and other advantages.

Coating properties: excellent rheology under high shear; Coating thickening efficiency is high; The coating has excellent water retention performance and good coating operation performance.

Coated paper physical properties: improve printing performance, improve smoothness and roughness.

Performance advantage

1) Water retention performance and rheological properties under high shear viscosity are better than CMC;

2) Better coating thickness, coverage and less printing speckle than CMC;

3) Give the coating better smoothness and gloss;

4) The dosage is 1/3 or less of CMC, with good economy;

5) Liquid, directly added, easy to use, saving equipment investment and preparation costs;

6) Thickening water retaining agent has microbial stability and can reduce the amount of fungicide.

Principle of action:

The high molecular weight polymer, which is moistened and hydrated, occupies the space of the solution, resulting in an increase in the viscosity of the solution.

• As the polymer concentration increases, physical entanglement between polymer molecular chains occurs. This results in a high thickening efficiency.

• Hydrophobic groups on the polymer can be associated with each other, resulting in increased viscosity. These hydrophobic groups can also be coated

The latex particles, surfactants and pigment particles in the material are associated, thereby increasing the viscosity.

• Hydrogen bonding occurs between the thickener and the solution, and can also occur between the thickener and the additive. The temperature rises,

The hydrogen bond is weakened, resulting in a decrease in solution viscosity. The thickener molecules can also be adsorbed on the pigment surface by hydrogen bonding.
