Silicone sealant formulations for highly durable seals on sensitive or sanitary substrates
Our silicone sealants are renowned for their sanitary properties, as well as their exceptional resistance to aging, weathering, mold, radiation, fire, water, and volatile chemicals.
As some of our most versatile sealant solutions, our silicone-based products are capable of providing exceptionally tough, yet flexible seals for a variety of applications across domestic, commercial, and industrial installation processes.
Available in a variety of low to mid modulus formulations, our silicone sealants offer elastic properties to suit your needs. And unlike other sealants with high levels of flexibility, our silicone formulations don’t compromise on durability. Boasting exceptional resistance to extreme temperatures, corrosive fluids and volatile airborne chemicals, our silicone sealants are even tough enough to replace automotive gaskets.
Bostik silicone sealants are also highly resistant to mold, freeze-thaw conditions, and various forms of radiation, making them ideal for use in food preparation areas. Acid free and with very low emissions, these food-grade sealants are some of the most sanitary on the market.
Our silicone-based products not only excel at sealing synthetic surfaces, but also notoriously difficult materials like concrete and natural stone. Their ability to provide highly workable, non-sag, low odor seals across glass, timber and roofing materials means they provide truly versatile solutions for construction projects.
