Dymonic FC Fast Curing, Low Modulus, Silane
End-Capped, Polyurethane Hybrid Sealant
Fast Skinning, Low Modulus, One-Component, Smooth
Finish Polyurethane Joint Sealant
Fast Skin Time, Less Dirt Pick Up
Available in Several Colors
Tremco 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.

Joint Design: Dymonic FC may be used in any vertical
or horizontal joint designed in accordance with accepted
architectural/engineering practices. Joint width should be 4 times anticipated
movement, but not less than 1/4” (6.4mm).
Closed cell backer
rod or reticulated polyethylene backer rod is recommended as joint backing
to control sealant depth and to ensure intimate contact of sealant with joint
walls when tooling. Where depth of joint will prevent the use of backer rod, an
adhesive backed polyethylene tape (bond breaker tape) should be used to prevent
three-sided adhesion. All backing should be dry at time of sealant application.
