Product Description

Product Description

Our hydrophobic silica is prepared by the chemical reaction of hydrophilic silica and silane coupling agent. It is hydrophobic and does not disperse in water. Hydrophobic silica products are characterized by low moisture absorption, good dispersion, and rheological regulation even for polar systems. Some products, on the basis of hydrophobic treatment and then through structural modification, can provide further help for customers to develop new products and improve the performance of products. For example, in liquid systems, high amounts of hydrophobic silica can be added with little effect on the viscosity of the system.

 

 

Application

Hydrophobic silica is the most suitable rheological agent in processing. Thickening of polar liquids, such as epoxy resins. Defoaming agent; Reinforcement of silicone elastomer; For example, in molded products, good hydrophobicity, improve corrosion resistance, improve dielectric properties. Such as in cable composites, powder flow AIDS, fire extinguishing agents, in coatings and plastics to improve scratch resistance. It can be widely used in engineering plastics, modified plastics, silicone rubber, defoamer, paint, ink, fire extinguishing agent and powder coating.
