Part # : 24SHB3

HB-139 Hydrophobic Fumed Silica (200 m2/g)

HB-139 is a structure-modified hydrophobic fumed silica which is created by subjecting hydrophilic grades with BET of 200 m2/g to chemical post-treatment with PMDS (Polydimethylsiloxane). Featuring good thickening effects, high water resistance, and good free-flow characteristics, it is well-suited for transparent powder systems. This product is designed for use in coatings, inks, and adhesives & sealants.
Priced per lb.
