Dymonic® FC is a fast-curing, single-component, low-modulus, hybrid sealant formulated with proprietary silane end-capped polymer technology. Dymonic FC offers a high-performance, durable, flexible seal that performs excellently in moving joints and exhibits tenacious adhesion to substrates once fully cured.

Typical applications for Dymonic FC include expansion and control joints, precast concrete panel joints, perimeter caulking (windows, door, panels), EIFS, aluminum, masonry, and vinyl siding.

Dymonic FC is fast-curing with a skin time of 60 minutes and a tack-free time of 3 to 4 hours. This significantly reduces dirt attraction and improves the overall asthetic look. Additionally, Dymonic FC will not green crack due to early movement. The low-modulus nature of Dymonic FC allows it to provide exceptional movement capability of ± 35%.

We carry Gray and White colors for Dymonic FC, with the option of painting over the sealant. Dymonic FC is easy to use for immediate application with conventional caulking equipment, with no mixing required.
