Tremco Commercial Sealants & Waterproofing (CS&W), a leading North American supplier of integrated building envelope solutions for the commercial construction industry, announced today that it has introduced Dymonic® 100, a new breed of urethane sealant that expedites construction schedules and simplifies product selection by providing exceptional movement, the capability to adhere to both damp and green concrete and versatility for use with Tremco’s waterproofing membranes, traffic coatings and air barrier membranes.
With +100% extension and -50% compression capability in typical field conditions, Dymonic 100 is perfectly suited for expansion and control joints, precast concrete panel joints, perimeter caulking (around windows, doors and panels) and aluminum, masonry and vinyl siding. Even after 365 days under the ISO 10590 test (normally 28 days), Dymonic 100 extended 100% when tested in the lab. This makes it ideal for more demanding.
The aliphatic urethane technology used in the Dymonic 100 formulation enables it to be applied to green concrete 24 hours after the removal of concrete formwork and damp concrete within about 30 minutes after the rain has stopped. This eliminates long delays waiting for the product to cure and extended weather delays. With standard urethane sealants, generally a day is lost after a rain to avoid outgassing. Even in perpetually humid conditions, there is no loss of adhesion or outgassing with Dymonic 100.
The Dymonic 100 urethane technology also allows it to be used under and over Tremco’s asphalt and acrylic-based air barriers as well as its urethane pedestrian or vehicular coatings and waterproofing membranes. This takes the guesswork out of product selection. One versatile, high-performance sealant can be used for seams, at transitions, in joints and detail work around penetrations, screw heads and brick ties.
During QUV accelerated aging testing (2000 hours), Dymonic 100 does not yellow, craze or chalk. The white retains its whiteness as well as a silicone. It has a fast cure and skin time, reducing the opportunity for dirt pick-up, and is paintable, VOC-compliant and provides a 10-year warranty. It is available in 21 standard colors in both cartridges and sausages.
