Application
Crosile®CPTMO is an important starting material for sol-gel processes. It adds a certain amount of organic character to the siloxane network, due to the propyl group in the product.
Crosile®CPTMO is often used in conjunction with in order to control the amount of inorganic character of the inorganic network. It contains a propyl group that adds organic character to the products.
