Evonik was granted the first patent for silanes in 1928. Since then, we received more than 400 patents. Our position as a world’s leading manufacturer of functional silanes is due to our uncompromising commitment to quality and highest purity of our products. Evonik set high standards, mainly in efficiency, connection with resource conservation, compatibility and implementation of the Responsible Care® initiative. To meet these ambitious requirements, we produce all standard and specialty products in low-waste and energy cycles, or closed-loop processes.
