Tremco Dymonic FC Black 20oz Sausage

Tremco Dymonic FC Black 20oz Sausage is a fast-curing, high-performance polyurethane hybrid sealant designed for demanding applications requiring long-lasting flexibility and strong adhesion. Formulated with proprietary silane end-capped polymer technology, this one-component, low-modulus sealant is moisture-curing and delivers exceptional performance in dynamic joints, resisting cracking or crazing even under UV exposure.


Ideal for both interior and exterior construction, it adheres tenaciously to common substrates like precast concrete, aluminum, vinyl siding, EIFS, and masonry. It can be applied directly from the tube—no mixing required—and its paintable surface ensures seamless integration into your project’s finish. With a fast skin time of 60 minutes and tack-free time in just 3–4 hours, Tremco Dymonic FC significantly reduces dirt pickup and speeds up workflow on the jobsite.
