Dow's Latest Collaborations in Advancing High-Performance Building Façade Solutions and Sustainability

Signaling a shared commitment towards carbon neutrality, Dow Chemical International Private Limited (Dow India), and Glass Wall Systems India signed an agreement for Dow to supply DOWSIL Facade Sealants from Dow's Decarbia portfolio of reduced-carbon solutions, for Glass Wall System's curtain wall system.

This collaboration demonstrates a dedication from organizations in the building and infrastructure industry to reduce embodied carbon in building materials. Dow's carbon-neutral silicone sealants for building façades, verified through the PAS 2060 standard, have the advantage of a lower embodied-carbon footprint due to Dow's investments in the decarbonization of its silicon metal assets in Brazil.

"Silicone sealants used in façades are already known for their positive contribution to lowering the operating carbon emissions coming from the cooling and heating of buildings, as they provide durable bonding in insulated prefabricated façade elements," says Jean-Paul Hautekeer, global marketing director for building and infrastructure, Dow Consumer Solutions. "With this program, we are going one step further by eliminating their embedded carbon. We appreciate the shared vision and collaboration with Glass Wall Systems."

Dow also announced a capacity expansion from its minority equity investment in SAS Chemicals GmbH, a German-based specialty chemical producer of sealants and components used in insulating glass manufacturing, to create a more holistic façade offering.

For over five decades, silicone insulating glass sealants from Dow have been used in various commercial structural glazing applications. With the capacity expansion at SAS Chemicals, Dow aims to have a broader range and capacity of high-performance adhesives and sealants solutions for insulating glass manufacturers.

"With expanded capacity and products, our customers will benefit from a total-system solution of sealant and adhesive technologies that meet the performance, productivity and quality needs of the façade and window segments," says Hautekeer. "This investment is reinforcing our position as a leading materials science supplier in the global façades industry." 

Dow has a minority equity investment in SAS Chemicals, a company that produces and supplies adhesives and sealants that are used to manufacture insulating glass windows. As part of this capacity expansion, SAS Chemicals will strengthen its operations in Germany and expand production in Turkey, which is situated to efficiently serve the global market and complement existing SAS operations. SAS Chemicals' Turkey plant is expected to start up in June 2024.
