Hydrophobic Fumed Silica LC-HFS304

LC-HFS304 is a hydrophobic fumed silica based on hydrophilic white carbon black with a specific surface area of 200, deeply treated with polydimethylsiloxane surface, and modified with special spatial structure. It has good dispersibility and can achieve dispersibility under low shear conditions, making it suitable for particle sensitive application systems.

Features & Benefits of Hydrophobic Fumed Silica LC-HFS304

It exhibits excellent anti settling performance in epoxy colored sand, providing a better construction feel.
Excellent dispersibility and anti settling function are demonstrated in polyurea coatings, thin coating coatings, and coatings with low shear processing limitations.
In addition to excellent thickening, thixotropy and anti-aging properties, it avoids conventional particle problems when used in polyurea and true porcelain seam sealants.
It can effectively avoid common defects such as white spots and orange peel. Extremely strong negative charges are used for carbon powder, and
In high-strength adhesives, it can provide excellent reinforcement performance.

Applications of Hydrophobic Fumed Silica LC-HFS304

Carbon powder and powder coating
epoxy colored sand
Coatings and organic silicon thin coatings
Polyurea, genuine ceramic grout and epoxy adhesive
Wind energy, solar energy adhesive and automotive sealant
