HB-152
Characteristics
HB-152 is hydrophobic fumed silica which is produced by HL-200 after chemical post-treatment with DDS ( Dimethyldichlorosilane ).
Applications
RTV silicone rubber,especially RTV-T
Adhesives & Sealants
Coatings & Printing ink
Powder Coating
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
