Properties:
1. Provides thickening and reinforcing properties in MS sealants and silicone sealants requiring high transparency, preventing transparency loss caused by filler addition.
2. Exhibits excellent dispersion and anti-settling properties in thin-film coatings, preventing particle and pinhole defects on coated surfaces.
3. Delivers outstanding reinforcement properties in adhesives and silicone materials.
4. Exhibits superior anti-settling effects in coatings and inks while providing higher thixotropy and lower viscosity increase.
