Silicone sealants for the construction industry

Professionals in the building and construction sectors need high-performance and cost-effective sealants to deliver what consumers and homeowners demand. These products must provide flexible joints to bond construction materials and to protect windows, doors and facades against fluctuations in temperature, humidity, wind and other environmental conditions.

Elkem Silicones has supplied the building and construction industry since 1957, when it invented the first Silicone sealant. Today, we market two dedicated product lines:

  • Bluesil™ Acetoxy Sealant technology for general purpose and specialty applications, including sanitary products, that are fast curing and offer storage stability and long shelf life

  • Bluesil™​ Alcoxy technology (neutral) in filled and unfilled versions, offering high adhesion properties and low modulus levels.

Our specialist consultants are available to help formulators and cartridge repackers find the features they need, including semi-finished products (master batches) and auxiliaries such as primers. We work with our customers from the R&D stage to after-sales servicing and we provide regulatory assistance (Construction Standards) to meet the needs of the most demanding markets.
