EINECS No. 231 545 4 Precipitated Silicon Dioxide HF-205 For Powder Coatings

Precipitated Silicon Dioxide HS Code: 281122 Used As Anti-Adhering for Powder Coatings

Introduction

White Carbon Black SiO2
Molecular formula: SiO2
CAS No.: 10279-57-9
H.S. Code: 28112290

Performance

It is odorless, insoluble in water and acid. non-combustion.

It is widely applied to solid & liquid silicone rubbers, paints, coatings, inks, resins, adhesives, rubber and plastic films, master batch, cable material, cable sheath, resin glass fiber reinforced plastics, composites, electronics, cosmetics, pharmaceuticals, and other industries. It is capable of enhancing strength, improving abrasive resistance, high-temperature resistance and tear resistance, as well as increasing dielectric properties if they are applied in silicone rubber products. It can prevent sediment, agglomeration and sagging, improve stability, adjust water content.

When it is applied to paints and inks, it will function as reinforcer, thickening agent, and processing agent, avoid sediment and agglomeration, thus to improve stability and promote adhesion effects. When it is applied in resin glass fiber reinforced plastics and composites, it can prevent sagging, improve aging-resistance and anti-impact strength, increase surface smoothness and so on.
