5 FAQs of nano hydrophobic fumed silica sio2 treated fumed silicon dioxide HB-615 white carbon black powder factory

What is nano hydrophobic fumed silica (HB-615)? Nano hydrophobic fumed silica HB-615 is a high-purity silicon dioxide powder treated with a hydrophobic agent, creating a water-repellent surface. Its ultra-fine particles (7-40 nm) and large surface area enhance performance in applications requiring reinforcement, viscosity control, or moisture resistance.

How is HB-615 different from untreated fumed silica? HB-615 undergoes surface modification using silane or silicone oil, making it repel water. Untreated fumed silica is hydrophilic (water-attracting), limiting its use in moisture-sensitive environments. HB-615’s hydrophobicity improves compatibility with polymers, coatings, and adhesives, reducing clumping in humid conditions.

What are the primary applications of HB-615? It is used in silicone rubber, paints, coatings, adhesives, and sealants to improve mechanical strength, rheology, and weather resistance. It also serves as a flow aid in powders, a matting agent in films, and a filler in composites requiring water repellency. HB-615 is ideal for electronics, automotive, and construction industries.

Is HB-615 safe to handle? While non-toxic, HB-615’s fine particles can cause respiratory irritation if inhaled. Use PPE (masks, gloves, goggles) and ensure proper ventilation. Avoid direct skin contact or ingestion. Follow local regulations for chemical handling and disposal. Store away from moisture and incompatible substances.

What is the shelf life and storage recommendation for HB-615? When stored in a cool, dry place in sealed containers, HB-615 remains stable for up to 24 months. Exposure to moisture or high temperatures may reduce effectiveness. Keep containers tightly closed and away from oxidizing agents or strong acids.
