Wacker_New_Renewable_SealantWACKER launches ELASTOSIL® eco brand, a silicone sealant product line manufactured using bio-based methanol in Europe. The new brand is based on the REDcert2 standard which confirms the traceability of renewable raw materials across WACKER’s entire production process – from the initial upstream process to the ready-to-use silicone sealant.

ELASTOSIL® eco - Sustainable Silicone Sealant


ELASTOSIL® eco is WACKER’s first approach to encompass and compensate all fossil-based raw materials and additives in the product formulation by using bio-based methanol. To qualify, the purchased biomethanol has to be obtained from certified sustainable sources. Raw material volumes needed for manufacturing undergo regular audits as part of an annual recertification process.

WACKER offers a comprehensive carefree package and thus the chance to be a first-mover supplying a sustainable silicone sealant in the market”, said Axel Schmidt, responsible for the company’s sealants & adhesives business.

Currently, acetic and alkoxy curing silicone sealants containing 100 percent silicone are available as ELASTOSIL® eco products. Acetoxy curing sealants have a long shelf life and are frequently used for professional construction applications. Alkoxy curing grades exhibit outstanding adhesion and elongation in glazing and window applications as well as selected industrial applications. Both are equally available as versions for professional sanitary applications.

Portfolio Offers Outstanding Adhesion Profile


The ELASTOSIL® eco portfolio also includes a chalk filled alkoxy-curing silicone sealant. With its matt appearance and outstanding adhesion profile, it is a grade found in weather-seal applications. “The performance of the standard and fossil-free grades is completely identical”, Schmidt emphasizes. “We deliberately selected our premium quality sealants for the start in order to show our customers that we accept no compromise on quality.”

While WACKER produces and packages the sealant, compounders and distributors will be able to market the products under their own brand based on ELASTOSIL® eco. “Individual homeowners across Europe and professional users will be able to purchase eco-friendly and resources saving silicone sealants for any kind of improvement activities”, Axel Schmidt points out. “Our pioneering ELASTOSIL® eco brand paves the way to an increasing share of sustainably manufactured construction chemicals in the years to come.”

The mass balance approach of ELASTOSIL® eco encompasses the entire formulation of the ready-to-use silicone sealant and compensates all fossil-based raw materials and additives by using bio-based methanol.
