Precipitated Silica For Coating and Ink

Description

1, Precipitated Silica in Coatings widely used as thickening agent, anti-settling agent and matting agent. It also improves abrasion resistance, glossiness and stability.

2, The production of precipitated silica starts with the reaction of an alkaline silicate solution with a mineral acid. Sulfuric acid and sodium silicatesolutions are added simultaneously with agitation to water. Precipitation is carried out under alkaline conditions. The choice of agitation, duration of precipitation, the addition rate of reactants, their temperature and concentration, and pH can vary the properties of the silica.

Application:

1, Unsaturated Polyesters: Avoid drop lets and wrinkles.

2, Pigment: Prevents precipitation, improves dye absorption, and improves the dispersion ability.

3, Emulsion Paint Filler: Improves thermal stability.

4, Ink: Matting Agents, improved non-setting properties, dispersion, suspension and abrasion resistance.

5, Printing Ink: Improve the printing effect, eliminating influence of non-dispersed ink penetration. Improve the wash ability, and the glossiness.

6, Powder coatings, Atomic dust coating, Priming paint, Mastic coatings.

Characters

1, Easy to disperse, it make the surface of the coating with unique features.

2, Excellent thixotropic, better thickening and anti-settling.

3, Greater flexibility when you add the silica.

4, Better weathering.
