Tremco Dymonic 100 Precast White 10oz Cartridge

Tremco Dymonic 100 is a high-performance, single-component polyurethane sealant specifically formulated for demanding construction and maintenance applications. It is designed to handle joint movement and exposure to challenging environmental conditions without compromising durability or adhesion. The non-sag, medium-modulus formulation ensures that the sealant remains in place after application, even on vertical or overhead surfaces, while still offering the flexibility needed to accommodate structural movement.

One of the key strengths of Dymonic 100 is its ability to bond tenaciously to a wide range of common building materials, including concrete, masonry, aluminum, vinyl, and other façade components. It performs exceptionally well on damp or recently poured green concrete, eliminating the need to wait for substrates to fully dry — saving time and labor in the field. This capability is especially useful in fast-paced or weather-dependent project schedules.

Dymonic 100 is also engineered to withstand the elements. Its UV-stable composition resists fading, chalking, and degradation under prolonged sun exposure. It maintains elasticity in a broad temperature range and performs reliably in both above- and below-grade settings. Thanks to its combination of strength, movement capability, and environmental resistance, Dymonic 100 is trusted by contractors and maintenance professionals for use in both new construction and restoration work. Whether used to seal expansion joints, perimeter gaps, or window openings, it delivers long-lasting protection and peace of mind.

Data Sheet

Tremco Dymonic 100 is a versatile sealant trusted for a wide range of professional applications. It is frequently used to seal expansion and control joints in concrete and masonry, where movement and exposure to the elements demand a flexible, durable solution. Maintenance teams also rely on it for perimeter sealing around windows, doors, and wall panels—areas that require reliable protection from air and moisture infiltration.

In addition to standard joint and perimeter applications, Dymonic 100 is ideal for use as a fluid-applied flashing around curtain wall assemblies and fenestration systems. It adheres well to aluminum, vinyl, and EIFS surfaces, offering strong, weather-resistant bonds. Its ability to perform in water-immersed conditions without outgassing makes it especially valuable in challenging environments. Dymonic 100 is also approved for use with Nudura insulated concrete form (ICF) systems, further expanding its versatility across modern construction methods.
