Dymonic 100 – Best-in-Class Sealant for High-Movement & UV-Exposed Joints

Meet the ultimate sealant for demanding applications. Dymonic 100 is a high-performance, medium-modulus polyurethane sealant that redefines versatility and durability. Featuring an industry-leading movement capability of +100/-50%, it handles the most dynamic expansion and control joints with ease. Its exceptional UV stability ensures it will not crack, craze, or yellow, even under the most extreme and prolonged sun exposure, making it the perfect choice for exterior facades.

A groundbreaking feature of Dymonic 100 is its ability to adhere to damp or "green" concrete just 24 hours after pouring, dramatically accelerating construction schedules. Combined with its low VOC content, paintable surface, and resistance to jet fuel, it delivers unparalleled performance for architects, contractors, and engineers.

Key Features & Benefits:

• Best-in-Class Movement: Unmatched +100% extension / -50% compression capability for the most demanding expansion joints.
• Extreme UV Stability: Formulated with extreme UV resistance, it will not crack, craze, or yellow, maintaining aesthetics and performance long-term.
• Application on Green Concrete: Can be applied to 24-hour-old damp concrete, accelerating project timelines for membranes and coatings.
• Innovative Polymer Technology: Prevents out-gassing (unlike traditional sealants) for a smooth, professional finish and superior adhesion.
• Versatile Adhesion: Tenacious bond to concrete, precast, aluminum, masonry, vinyl siding, and more, often without a primer.
• Paintable & Low VOC: Allows for color matching on facades and is safer for the environment and applicators.
• Jet Fuel Resistant: Suitable for use in demanding environments like car parks, fuel stations, and aviation hangars.

Primary Applications:

• High-Movement Expansion & Control Joints: In concrete structures, parking decks, and bridges.
• Precast Concrete Panel Joints: Sealing between panels on building facades.
• Perimeter Caulking: Around windows, doors, and cladding panels.
• Under Waterproofing Membranes: As a sealant and as a fluid-applied flashing in rough openings.
• Industrial Applications: Areas exposed to fuels, chemicals, and harsh weather.

Why Choose Dymonic 100?
Dymonic 100 isn't just another sealant; it's a technological leap. Where other products fail under UV exposure or require long cure times before application, Dymonic 100 thrives. Its unique combination of early adhesion, colossal movement capacity, and exceptional UV resistance makes it the single-sealant solution for a vast range of critical sealing applications.

Dymonic 100 is not recommended for:
Natural rubbers such as EPDM, PVC or TPO.
Use on bitumen will result in discolouration.
Allow to fully cure prior to installation of nearby silicones.
Use with adequate ventilation.
Use in chlorinated, heavy or waste water.
