A plant to manufacture chlorosilanes requires well-grounded expertise in the chemistry of these hazardous substances. Producers of solar energy components across the globe seek partnerships with Evonik Industries because the Siridion® trademark is backed by more than 60 years of experience. Siridion® chlorosilanes can be supplied directly or in the form of a Verbund (fence-to-fence). No matter the business model, our priorities are the same: the unsurpassed purity of the products, the absolute reliability of production and logistics, and close cooperation with our customers.
