Characteristic

FM-H-B152 is hydrophobic fumed silica which is produced by hydrophilic fumed silica with specific surface area of 200m²/g after chemical post-treatment with DDS (Dimethyldichlorosilane)

Applications	Properties
● RTV silicone rubber, especially RTV-T	● Higher hydrophobicity,thixotropy,thickening, transparency and reinforcement
● Adhesives & sealants	● Anti-settling,anti-sagging agent
● Coating & printing ink	● Rheology control in adhesives
● Powder coating	● 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
