Polymer dispersant  HINOACT

Polymer dispersants adsorb onto the surface of pigment particles to prevent the particles from aggregating, and thus, these dispersants serve great function in the production of printing ink, coating materials, colorants, plastic products, and other pigment dispersions. The use of a polymer dispersant has the potential to improve many pigment characteristics such as the concentration, productivity, fluidity, and stability.

Advantageous Effects

Manufacturing

Improved fl uidity of a mill base contributes toward raising the concentration of the resulting pigment ( →Improvement in the ease of handling and productivity).

Milling time of a mill base is shortened ( → Cost reduction).

Product Quality

Prevents aggregation and sedimentation Improves storage stability

Obtains high-gloss and high-colored coating materials Eliminates flooding of colorants

Alumina sol

We developed alumina sol with various particle sizes and shape by use of aluminum alkoxide as a row material by sol-gel methods. Our alumina sols have high transparency and high purity. High transparency coating film alumina-polymer compound film can be fabricated form our alumina sol.

Crystal form of our alumina sols are boehmite. There are many hydroxide on the surface. The hydroxides are protonated by acid and are charged positively. Boehmite particles have positive charge at a pH of bellow 9. Boehmite particles can be dispersed without dispersant, because of repelling force between particle and particle. So stability of boehmite particles are depended on pH Value.

Application of Alumina sol

(1) Coatings

Corrosion and Oxidation of substrate such stainless and glass can be inhibited by alumina coatings.

(2) Fillers for polymer film

The boehmite-added PVA films show lower thermal expansion coefficients than the PVA film without boehmite, thus, the addition of boehmite particles into the PVA films improves the thermal stability of the films. It is interesting that longer boehmite particles especially , the fiber of 1400nm in length, remarkably improve the thermal stability of the PVA films. Lower picture show the result of heat-resistance test. PVA film without boehmite particle shrunk and melted. And The color of film turn from colorless to brown. On the other hand, PVA containig 20wt% of boehmite particle didn’t shrink and melt.
