Product Description
Our product hydrophobic silica by hydrophilic silica and silane coupling agent made by chemical reaction. It has hydrophobic (hydrophobic) and cannot be dispersed in water. Hydrophobic silica product features are: low hygroscopicity, good dispersibility, even for polar system has the rheological adjustment ability. Some products, on the basis of hydrophobic treatment by structure modification, can develop new products and improve the performance of the product to customers provide further assistance. In liquid in the system, for example: hydrophobic silica can achieve high content, but little impact on the viscosity of the system..
Features :
Hydrophobic silica used in processing is the most appropriate rheological additives. Polar liquid thickening, such as epoxy resin. Broken bubble defoaming agent; Silicone elastomer reinforcement; As in moulded products, good hydrophobicity and improve the anticorrosion, to improve the dielectric performance. Such as cable compounds, powder flow aid, fire extinguishing agent, improved resistance to scratches in the paint and plastic. Can be widely used in engineering plastics and modified plastics, silicone rubber, defoaming agent, paint, ink, fire extinguishing agent and powder coating.
