Tremco Dymonic 100 Limestone 10oz Cartridge
Tremco Dymonic 100 Limestone is a single-component, medium-modulus, non-sag polyurethane sealant in a 10.1 oz cartridge for expansion and control joints, precast panel joints, and window, door, and panel perimeters. Because it adheres to damp or green concrete without outgassing, it suits joints on fresh concrete work.
- Accommodates +100/-50% movement in typical field conditions.
- Resists cracking, crazing, and yellowing under extreme UV exposure.
- Holds up to jet fuel and water immersion service.

Frequently Asked Questions
What adhesion does Dymonic 100 deliver on damp or green concrete?
Tremco reports adhesion to green concrete above 25 pli and to damp concrete above 20 pli (ASTM C794), compared with 35 pli on cured concrete. Its polymer technology, shared with TREMproof 250GC and Vulkem 45SSL, lets it bond to damp or green concrete without outgassing.
What skin time and tack-free time should a crew plan for with Dymonic 100?
Tremco reports a 2 to 3 hour skin time (ASTM C679) and a 6 to 8 hour tack-free time at 73.4°F (23°C) and 50% RH, a profile the TDS credits with significantly reducing dirt attraction.
What joint movement can Dymonic 100 handle on expansion and precast panel joints?
It is rated ±50% under ASTM C719 and +100/-50% under modified ASTM C719 in typical field conditions, and it meets ASTM C920 Type S, Grade NS, Class 50, Use NT, T, M, A, O, I. Typical tensile strength is 350 to 450 psi with 800 to 900% elongation and a 100% modulus of 75 to 85 psi (ASTM D412).
What application and service temperatures apply to this polyurethane sealant?
Dymonic 100 is applied at 40 to 100°F (4 to 37°C), and Tremco directs work below 40°F to its Cold Temperature Sealant Application Recommendations bulletin. Once cured, the service temperature range is -40 to 180°F (-40 to 82°C).
What flashing and fire test results support Dymonic 100 at rough openings?
It meets ICC Section R703.8 Flashing through AAMA 714-15 for liquid-applied flashing, passes NFPA 285 fire resistance of assembly, and posts 5 smoke development and 5 fire spread under ASTM E84 (10, 10 under CAN S102). It also passes ASTM C1305 crack bridging and ASTM D1970 nail sealability, and it meets TT-S-00230C Class A, Type II.
What water exposures can a Dymonic 100 joint handle?
Tremco rates it suitable for water immersion, and adhesion to concrete after immersion stays at 30 pli under ASTM C794. It is not recommended for chlorinated, potable, heavy, or waste water.
