Properties
Good hydrohpobicity, thixotropy, thickening, transparency and reinforcement performance
Anti-settling and anti-sagging agent
Free flow aid and anti-caking aid for powders
Thixotropy and reinforcement in RTV silicone sealants, the hydrophobic feature gives RTV silicone sealants a long shelf-life.
