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% total joint movement. As a result, this rugged but flexible sealant is ideally suited for use in institutional 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.
Dynaflex™SC not only is more flexible than epoxy in composition but also satisfies the concerns for color coordina tion. It is available in two standard colors, and can be painted to blend with adjacent surfaces.

Joint Design: The width of active joints should be a minimum of 8 times the anticipated movement. The width or depth of the joint should not be less than 1/4” (6 mm). In joints up to 1/2” (12 mm), but not exceeding 1-1/4” (31 mm), the depth should be maintained at 1/2” (12 mm). For joints wider than 1-1/4” (31 mm), please consult our Technical Service department
Priming
Security caulking requires exceptional adhesion, particularly in containment areas like inmate cells, etc. Since the sealant’s higher hardness puts extra stress on the bond line, P-75 primer should always be used on porous substrates to obtain the proper adhesion. Steel, aluminum, polycarbonate and glass should be primed with P-120.
Limitation
Should not be used where it may come into contact with food products, or harsh chemicals such as acids, strong alkalis, ketones, etc.

<div itemscope itemprop="acceptedAnswer" itemtype="https://schema.org/Answer">
<div itemprop="text">
<p style="font-size:13px">In the majority of building projects, sealants are used solely to protect the building. However, when the building is a correctional facility, behavioral health unit, school, or child care center, there is much more at stake. It’s important that sealants cannot be pulled from joints. To remove sealant material could mean exposing a joint opening in which someone could hide contraband, causing injury from misused material, or ingestion of loose material. Security sealants contain properties that prevent any tampering that could endanger incarcerated persons, patients, workers, children, and the general public.</p><br><p style="font-size:13px"> As budgets are cut for government-run institutions, it becomes increasingly di cult for them to provide their fundamental services. Preventative maintenance, such as the application of security sealants, can pay for itself in the form of reduced ongoing maintenance costs and liability mitigation.</p>
