GS-204 is a specialized fumed silica that originates from a hydrophilic silica base with a specific surface area of 200 m²/g. It undergoes a deep surface treatment using polydimethylsiloxane, which renders the material hydrophobic. Furthermore, this silica is specially modified to enhance its spatial structure, resulting in a unique three-dimensional arrangement that contributes to its advanced performance characteristics.
The most outstanding feature of GS-204 is its excellent dispersibility, which enables it to achieve superior dispersion even under low shear conditions. This property makes it particularly suitable for application systems that are sensitive to particle aggregation or where minimal mechanical input is desired. Its ability to integrate smoothly and uniformly enhances performance in various formulations without compromising system stability or integrity.

Properties:
1. When applied in polyurea and ceramic grout sealants, it not only delivers outstanding thickening, thixotropic, and anti-aging properties but also eliminates conventional particle issues.
2. Its high thixotropy and relatively low viscosity provide superior application feel for the adhesive compound.
3. Demonstrates outstanding dispersion and anti-settling properties in polyurea coatings, thin-film coatings, and formulations with low shear processing constraints.
5. Its exceptionally high loading capacity provides carbon black with enhanced electrostatic charging capability.
