Dynaflex SC Limestone Security Sealant is a one-part, non-sag, tamper-resistant elastomeric sealant formulated with silyl-terminated polyurethane (STPU) chemistry. It offers the rugged durability and strength of two-part sealants with the simplicity of a single-component application. Designed for high-security environments, Dynaflex SC provides high tensile strength, tear resistance, and an ultimate Shore A hardness of 55, while still accommodating 25% total joint movement.
This high-performance sealant is ideal for institutional and correctional facilities, public buildings, or any location prone to tampering and vandalism. It adheres well to masonry, metal, and polycarbonate substrates without a primer in most cases and is easily paintable to match surrounding surfaces.
