In today's rapidly developing industrial field, the demand for high-performance materials is increasing day by day. Among them, Yingchuang white carbon black R202, as a high-performance thickening and thixotropic agent, plays a crucial role in the fields of adhesives, sealants, epoxy and vinyl resins, adhesive coatings, cable adhesives, etc. This article aims to explore the mechanism of action, performance characteristics, and applications in various fields of Evonik white carbon black R202.

1、 The mechanism of action of Evonik white carbon black R202

Yingchuang White Carbon Black R202 is a hydrophobic gas-phase silica modified with dimethyl polysiloxane, which is made from hydrophilic gas-phase silica. The surface of its particles is fixed with long chains of polydimethylsiloxane, which has strong hydrophobicity. When this hydrophobic product is dispersed in a polar system, hydrophobic groups can protect the remaining silicon hydroxyl groups on the surface of silica to prevent excessive wetting. This special structure enables Evonik white carbon black R202 to have excellent thickening and thixotropic effects in polar systems.
