About Geocel: Setting the Standard in Sealants

Geocel Corporation, founded in 1974 and headquartered in Elkhart, Indiana, has spent over five decades earning the trust of professional contractors, builders, and repair specialists. For over 40 years, Geocel has been a trusted leader in premium roofing and construction sealants, delivering unmatched durability and performance for professional contractors and builders. That reputation wasn't built overnight — it was forged through a relentless commitment to quality and a willingness to innovate where others stood still.

Geocel was the first U.S.-based sealant manufacturer to receive ISO 9001 registration — a milestone that underscores the brand's dedication to quality management long before it became an industry expectation. Founded in 1974, Geocel's innovative sealants have been used in commercial, residential, industrial, and transportation (non-automotive) markets. Whether sealing a roof penetration on a commercial job site or making a durable repair on an RV, Geocel has a solution engineered for the task.

A Complete Portfolio Built Around Sealing Performance

At the heart of the Geocel lineup is its extensive range of Caulks & Sealants. From solvent-based and hybrid sealants to advanced silicone solutions, Geocel offers products engineered to meet every application's needs. Standout products like the Geocel 2300® Construction Tripolymer Sealant and the polyurethane-based 3300® have become go-to choices for professionals who need a bond that won't quit. Geocel 2300 provides superior UV resistance and flexibility, making it a favorite for demanding exterior applications where joints expand and contract with the seasons.

Beyond traditional sealants, Geocel also produces a respected line of Specialty Coatings & Paints. ProFlex® RV Rubberized Silicone White Roof Coating is a premium silicone rubber roof ideal for ponding water — an example of how Geocel bridges the gap between sealant chemistry and protective surface coating. These products are widely used in roofing, RV repair, and industrial maintenance applications.

Geocel's commitment to silicone chemistry also shines through in its RTV Silicone offerings. Products like the Geocel 8125 100% Silicone High Performance Acetoxy Cure Sealant deliver high modulus and high elasticity, providing durable performance while resisting fungus, mildew, ozone, UV radiation, and extreme temperatures. This makes them an excellent choice for demanding sealing applications where long-term weatherability is non-negotiable.
