Dymonic® FC is a low modulus, one-component, moisture-cure, polyurethane hybrid sealant. Formulated with proprietary silane end-capped polymer technology, Dymonic FC provides the best performance characteristics of polyurethane and silicone sealants.
Dymonic FC is a durable, flexible, sealant that offers excellent performance in moving joints and exhibits tenacious adhesion 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 & vinyl siding.
Dymonic FC is fast curing with a skin time of 60 minutes and a tack-free time of 3-4 hours to significantly reduce dirt pickup. It will not green crack due to early movement and has an exceptional movement capability of +/– 35%. Dymonic FC is also low VOC, paintable and will not crack or craze under UV exposure.
