Description

Hydrophobic fumed silica is a post-treated product. Different types of fumed silica can be selected as raw materials, and through the reaction of silanol groups with suitable compounds, hydrophobic silica products are obtained after special treatment. They are mainly used in powder coatings, adhesives, silicone sealants, and other fields. Especially in the field of powder coatings, they have special applications, playing an important role in promoting the fluidity of powder, maintaining the bulkiness of powder, and preventing powder from caking.

 

Performance advantages:

- High scratch resistance, medium viscosity, hydrophobicity, and smoothness;

- Good compatibility with organic solvents and good dispersibility in oil-based systems;

- Can improve the stability and anti-settling properties of coatings;

- Promote and maintain the fluidity and anti-caking properties of powder.

 

Application fields:

- Adhesives, sealants, defoamers, powder coatings: Promote the fluidity of powder;

- Silicone sealants: Used for enhancing and reinforcing silicone sealants and improving their storage performance;

- Electronic potting compounds, sealants, coatings, inks.
