Dynaflex is designed to achieve high tensile and tear strength, abrasion resistance and an ultimate Shore A hard ness of 55, yet withstand 25% total joint movement. As a result, this rugged, but flexible sealant is ideally suited for use in institutional and correctional facility installations but performs equally as well in other public buildings and facilities where ordinary sealants are easily damaged or torn out by idle tampering and acts of vandalism.
Application and Uses
- All interior joints and perimeters of fixtures, penetrations, vents, doors, windows and all other similar openings where a flexible security sealant is required.
- Interior window glazing.
- Heavy pedestrian traffic expansion and control joints for security and non security areas.
- Concrete joint applications requiring jet fuel resistance.
Technical Data
Applicable Standards: Meets Federal Specification TT-S-00227E, Class B, Type II, SS-S-200E, Type M; and ASTM C-920, Type M, Grade NS, Class 12.5, Use T1, M, O . Also exceeds the test requirements of ASTM C1247 for sealants exposed to continuous immersion in liquids. Acceptance by U.S. Department of Agriculture for use in meat and poultry processing plants.
Joint Design: 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” (50 mm). For joints wider than 1-1/4” (31 mm), please consult our Technical Service
Limitations:
Dynaflex is not to be used:
- When in direct contact with substrates that contain asphaltic or bituminous compounds.
- In active joints experiencing movementgreater than ±12-1/2% in compression or extension.
- In areas where it may come into contact with food products.
- In areas where it may be subjected to harsh chemicals such as acids, strong alkalis, ketones, etc.
