Primary Mastic SHC 104-90/91 is a premium CSPE rubber based mastic designed for industrial insulation and construction applications that require strong adhesion, long-lasting sealing, and excellent environmental resistance. Engineered for demanding conditions, it provides reliable performance by creating durable bonds and protecting insulation systems from moisture, weather, and UV exposure.

As a high-quality primary insulation mastic adhesive, SHC 104-90/91 adheres effectively to a wide range of construction materials, including timber, aluminium, stainless steel, carbon steel, marble, glass, cement boards, insulation boards, and other common industrial surfaces. Its versatile formulation makes it suitable for both new installations and maintenance projects.

The Primary Mastic SHC 104-90/91 is formulated using chlorosulfonated polyethylene (CSPE) rubber, offering excellent flexibility and adhesion even under changing temperatures and harsh outdoor environments. Once applied, it forms a durable seal that helps protect insulation systems from moisture ingress while maintaining long-term performance.

This CSPE rubber based mastic is widely used in industrial pipe insulation, HVAC systems, storage tanks, vessels, mechanical insulation, and process equipment. It is ideal for industries such as oil & gas, petrochemical, power generation, chemical processing, manufacturing, and commercial construction where reliable insulation materials are essential.
