Dynaflex SC is a unique one part, non-sag, tamper resistant elastomeric STPU ( Silyl-terminated polyurethane) joint sealant with many of the strengths of two-component security sealants but with the user-friendly ease-of-application properties of a one-component sealant. Dynaflex SC is designed to achieve high tensile and tear strengths, abrasion resistance and an average ultimate hardness of at least 55, yet still withstand 25% joint movement. As a result, this rugged but flexible sealant is ideally suited for use in instructional and correctional complex security installations but performs equally well in other public buildings and facilities where ordinary sealants are easily damaged or torn out by idle tampering and acts of vandalism.
