| Application |
Trimethoxypropylsilane is a versatile alkylalkoxysilane that serves multiple purposes in various industries. It is utilized as an important material in sol-gel production, providing a hydrophobic surface treatment for inorganic powders or filler materials. Additionally, it functions as a catalyst component for polyolefin production with Ziegler-Natta catalysts. In silicone sealant formulations, trimethoxypropylsilane acts as a neutral curing agent, crosslinking α,ω-silanol polydimethylsiloxanes in the presence of atmospheric moisture. It is commonly used as the main crosslinker for oxime silicone sealants, either alone or in combination with other oxime silanes to achieve specific properties such as cure rate and adhesion. |
