Substantial top quality Hydrophilic fumed silica for polyester, silicone, paints and coatings
hydrophilic fumed silica with a particular floor area of 200 m2/g .The unique particle dimension can be 5- 40 nm. It truly is a kind of higher purity white colloidal powder.
It is mostly utilized for large-temperature vulcanized silicone rubber, organic silicone defoamer, innovative printing ink, powEPTcoating, PVC resin, unsaturated polyester resin thickening, thixotropic agent, pharmaceutical powder, tabular planning, cosmetics and many others.
