Amorphous Silica industry grade silicon dioxide matting agent for plastics
Description
high transparency
The high purity of this series of products ensures their refractive index to be consistent with the refractive index of resin.
High heat dissipation
Special production process to make this series of products, quickly spread to the other surface of the paint, to extend the life of the paint.
High suspended property
This series of products are produced through special treatment to both internal and external structures. Even after long-time placement, there will be no precipitation and stratification to the paint.
High extinction
Advanced production technology not only increases the pore volume of the product, but also ensures the consistency and evenness of particle clearance, which achieves a high extinction rate.
High dispersion
The series of products can easily disperse in any sorts of paint. Generally, they can be fully dispersed after 10 minutes of mixing with 10 - 20M/S linear velocity and using regular high speed mixer.
