DynaFlex SC, Primer for Use on Non-Porous Aluminum & Glass, 1
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-compound security sealants but with the user-friendly ease of application
properties of a one-component sealant. Dynaflex SC is designed to archive 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 coordination. It is available in two standard
colors, and can be painted to blend with adjacent surfaces.
Limitations: DynaFlex SC is not to be used in active joints
experiencing movement greater than 12-1/2% in compression or extension. Nor
should it be used in areas where it may be subjected to harsh chemicals such as
acids, strong alkalis, ketones, etc.
