Data Sheet


Dymonic FC by Tremco is a fast cure, high performance, low modulus, one component, moisture curing, modified polyurethane joint sealant. It is specifically developed for sealing dynamically moving joints such as: expansion and control joints, precast concrete panel joints, tilt-up panel joints, curtain wall joints and perimeter caulking. Sausages are 15 to a case. Questions? Contact us

Dymonic FC is easy to apply with conventional caulking equipment. Ensure that the backer rod is friction fitted properly and any primers have been applied. Fill the joint completely with a proper width-to-depth ratio and then tool to ensure intimate contact of sealant with joint walls. Dry tooling is always preferred, although xylene can be used in limited amounts to slick the spatula if needed following the initial dry tooling. For a cleaner finish, mask the sides of the joint with tape prior to filling.

Closed cell 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.

Dymonic FC generally cures at a rate of 3/32” per day at 75 °F (24 °C) and 50% RH. Dymonic FC will skin in 1 hr and be tack-free in 3 to 4 hr. The cure time will increase as temperatures and/or humidity decrease. A good rule of thumb is one additional day for every 10 °F decrease in temperature

Excess sealant and smears adjacent to the joint interface can be carefully removed with xylene or mineral spirits before the sealant cures. Any utensils used for tooling can also be cleaned with xylene or mineral spirits.
