C C30 1

CC 301 is a dispersion with a silica content of 30%. The dispersed silica exists in an amorphous form, commonly known as colloidal silica.

CC 301 has a particle size of 7 nanometers, uniform particle size distribution, and a large specific surface area. It is a liquid with a specific gravity slightly larger than water. The surface has been modified with silane and has good storage stability.

CC 301 Product Features

01

  • Significantly improves paint film hardness, improves wear resistance, and has good surface finish

  • Prevent resin emulsion coating from sticking

  • Greatly improves the stain resistance, chemical corrosion resistance, scrub resistance and water resistance of the paint film

  • Improve the adhesion of the paint film, improve the anti-slip performance of the paint film, and maintain the brightness of the paint film for a long time

  • Significantly improve the thixotropic properties of the system and enhance the UV aging resistance and thermal aging resistance of the paint film

  • Improve the conductivity of the paint film and enhance the anti-static properties of the paint film

  • Achieve the same appearance and richness as solvent-based paints

CC 301 usage and dosage

03
 
The particle size of CC 301 is tiny. Compared with traditional colloidal silica, CC 301 can be used at a lower dosage. Different application fields require different dosages and methods. It is recommended to add it separately to water-based resins and emulsions. CC 301 should not be premixed with other additives. The addition amount is usually 10%-40% of the resin or emulsion content (5% to 8% of the total system).

 

Application in water-based wood paint

04
 
CC 301 with an emulsion content of 10%-40% is added to the one-component acrylic formula, and is combined with Momentive silane COATOSIL 2287 (2287 has good storage stability in water-based coatings, and is denser and has better performance by reacting with CC 301 coating), reaching the same fullness as solvent-based coatings.

be careful:

  • It is recommended to add it directly to the emulsion or resin without premixing it with additives.

  • The test of the added amount is directly related to the Tg of the resin. A low Tg can be used to add a high amount, and a high Tg can be used to add a small amount. Adding too much will result in poor chemical resistance and mechanical properties of the coating.
