Dymonic FC is a single-component, low-modulus, fast-curing, polyurethane hybrid sealant. It combines the best properties of polyurethane and silicone formulations for superior flexibility and durability.
Key Features
- Coverage Rate = 12 ft @ .5" x .25" (10.1 oz)
- Drying/Cure Time = 14 to 21 days
- Application Temperature = 40 to 90 °F (4 to 32 °C)
- Flexible movement capability: Handles joint movement up to ±35%, making it ideal for dynamic seals.
- Low-VOC and paintable: Environmentally considerate and can be painted once fully cured.
- UV-resistant: Remains stable and resists cracking or crazing under sun exposure.
Typical Applications
- Expansion and control joints in concrete and precast panels
- Perimeter caulking around windows, doors, architectural panels
- EIFS systems, aluminum, masonry, and vinyl siding interfaces
- Fire-rated assembly joints
Workability & Installation
- Moisture-cure technology: Only one component needed, curing begins on exposure to ambient moisture; no mixing required.
- Non-sag consistency: Applies cleanly with conventional caulking guns.
- Broad service temperature range: From roughly –40°F to 185°F (–40°C to 85°C).
- Backer rod or bond-breaker tape recommended: Prevents three-sided adhesion and controls sealant depth for effective joint movement.
