Hydrophobic fumed silica in adhesives

Introducing our Hydrophobic Fumed Silica, an essential ingredient for adhesives that guarantees outstanding performance. This high-quality product is designed to enhance the water repellency and durability of your adhesive formulations. With its unique hydrophobic properties, it ensures excellent adhesion even in moist and humid conditions. Our fumed silica offers exceptional reinforcement, improving the mechanical strength and stability of your adhesives. It also enhances the thixotropic behavior, preventing sagging and ensuring easy application. Trust our Hydrophobic Fumed Silica to elevate your adhesive formulations to new levels of effectiveness and reliability.

Hydrophobic fumed silica is a very effective thixotropic agent for polar epoxy based, urethane and vinyl ester based adhesives. In addition, when hydrophobic fumed silica is used, the adhesive Good storage stability can be obtained, even under high shearing force, it will become sticky, which guarantees good stability of the adhesive.

HJSIL R110 is a hydrophobic fumed silica after-treated with Polydimethylsiloxane (PDMS). In particular, the use of low-thickening hydrophobic silicas can improve the aging resistance of mechanically and basically cured adhesives and gel layers, which is an advantage for buildings close to the coast or in the sea, even where the environmental conditions are relatively inhospitable.
