CAB-O-SIL® TS-530
CAB-O-SIL® TS-530
CAB-O-SIL® TS-530 treated fumed silica is a high-purity silica which has been treated with a hexamethyldisilazane. The treatment replaces many of the surface hydroxyl groups on the fumed silica with trimethylsilyl groups. This treatment makes the silica extremely hydrophobic.
Features & Benefits
• TS-530 is an excellent reinforcing filler for elastomers. Its full surface treatment gives a low viscosity and its high surface area provide excellent reinforcement properties, such as tear strength.
• TS-530 reduces the water permeability of a coating, thereby increasing its corrosion and humidity resistance
• TS-530 is an effective dry powder carrier for oils such as perfumes, fragrances, pesticides, herbicides, and veterinary products.
• TS-530 can function as an anti-settling agent in coatings. With its reduced thickening potential, it will not raise the viscosity of the system which is of great benefit in high- solids systems.
• As a free flow agent, TS-530 is the most efficient of all the treated and untreated fumed silicas. This, combined with the potential to enhance the charging properties of a powder, makes TS-530 especially attractive for free flow applications in toners and powder coatings.
