DYMONIC® 100 - Technical Data Sheet - High-Performance Polyurethane Sealant

Nov 2, 2026

DYMONIC® 100 is a single-component, medium-modulus, non-sag polyurethane sealant engineered for durable, flexible sealing in high-movement applications. It delivers strong adhesion to substrates including damp or green concrete after full cure, with skin time of about 2 hours and tack-free time of 6–8 hours. Designed to resist UV-related cracking, crazing, or yellowing, it is low-VOC and jet fuel-resistant, and it supports use in expansion joints, glazing perimeters, and water immersion applications.

TECHNICAL DATA SHEET DYMONIC® 100 High-Performance, HighMovement, Single-Component, Polyurethane Sealant | PRODUCT DESCRIPTION
Dymonic® 100 is a single-component, medium-modulus, non-sag polyurethane sealant. Dymonic 100 offers a highperformance, high-movement, durable, flexible seal that performs excellently in moving joints and exhibits tenacious adhesion to substrates once fully cured. | | --- | | BASIC USES
Typical applications for Dymonic 100 include expansion and control joints, precast concrete panel joints, perimeter caulking (windows, doors, and panels), aluminum, masonry, and vinyl siding. Dymonic 100 is also an excellent choice as a fluid applied flashing material in rough opening perimeters for fenestration/window, door and curtain wall applications. Dymonic 100 is suitable for water immersion applications and will not out gas. | FEATURES & BENEFITS Dymonic 100 has been formulated with an innovative polymer technology, similar to TREMproof® 250GC and Vulkem® 45SSL, that allows it to be highly versatile and grants its unique capability to adhere to damp or green concrete without outgassing. The skin time of Dymonic 100 is 2 hours and the tack-free time is 6 to 8 hours. This significantly reduces dirt attraction and improves the overall asthetic look. Dymonic 100 has a movememnt capability of +100/-50% in typical field conditions with excellent performance in moving joints. The formula is low-VOC and UV-stable, meaning Dymonic 100 will not crack, craze, or yellow under extreme UV exposure. Additionally, Dymonic 100 is jet fuel-resistant and compatible with many common construction substrates. • Compatible with and can be coated over with Tremco's Vulkem Deck Coatings, ExoAir® Air Barrier products and the cold, fluid-applied TREMproof® line of below-grade waterproofing products • Accepted for use over Nudura Insulated Concrete Forms (ICF) There are 21 standard color options available for Dymonic 100, with the option of painting over the sealant. Dymonic 100 meets or exceeds the requirements of the following specifications: • ASTM C920 Type S, Grade NS, Class 50, Use NT, T, M, A, O, I • U.S. Federal Specification TT-S-00230C, Class A, Type II • CAN/CGSB-19,13-M87 • International Code Council (ICC) Section R703 .8 Flashing • AAMA 714-15 Specification for Liquid-Applied Flashing • NFPA 285 Listed Component Accepted fire rated systems: FF-D-1186, FW-D-1117, HW-D-1122, WW-D-1200, and BW-S-0006 | AVAILABILITY
