Applications

It is an important material in sol-gel production, it provides a hydrophobic surface treatment for inorganic powders or filter materials and it is one of the catalyst components for polyolefin production with Ziegler-Natta catalyst. It is mainly used as construction waterproofing agent/protective agent, inorganic filler surface treatment agent, and pigment dispersant.

Notes

Moisture sensitive. Store away from air and oxidizing agents and water/moisture. Keep the container tightly closed and place it in a cool, dry and well ventilated condition. Store under inert gas. Keep ignition sources away.
