Form-in-Place Gasket Sealants

Replace labor-intensive gasket technologies like tape, PSA die-cut gaskets, 2K epoxies, silicone beads, and RTV sealants with light-curable gasketing solutions.

Dymax form-in-place gasket material cures in place, on demand, in under 30 seconds using UV/Visible light-curing energy, eliminating the need for ovens, racking, stacking, or long-curing alternatives. Our gasket adhesives act as a barrier to prevent the absorption or penetration of air, dust, noise, and other elements. They are ideal for sound and vibration dampening, moisture and chemical protection, and air sealing. 

Light-curable liquid gaskets are formulated for precise automated dispensing to support high-volume production and consistency in bead profiles for single-wall, flat-surface, or channel configurations. When applied directly onto surfaces, these gasket sealants easily adapt to different component contours, even complex, irregular, or intricate forms, without custom tooling. They exhibit low compression set and maintain their shape, preventing the seals from weakening or breaking down over time due to prolonged pressure or repeat thermal cycling exposure.

The flexibility of Dymax form-in-place gaskets and the tight seals they form reduce the risks of leaks and contamination. This technology also eliminates the waste associated with poorly fitting or improper alignment of die-cut gaskets, reduces production time, and contributes to the lower labor cost required for manual application. With simplified application processes, users can achieve consistent and accurate gasketing, reducing the likelihood of errors and rework for improved productivity and product quality.

Dymax gaskets are used in fuel cell, EV, automotive, mobile, and electrical devices, lighting, HVAC, energy, and industrial hardware assemblies. Typical applications include sealing fuel cells and underwater enclosures, sound dampening, sealing automotive door handles and critical electronics, speaker and appliance-housing assembly, and sealing plastic and glass substrates and metal and plated surfaces.

Our materials are formulated to withstand challenging conditions, whether dealing with high-temperature environments, aggressive chemicals, or extreme pressures. Light-cure gasket solutions enable manufacturers to achieve accurate, consistent gasketing, prolonged service life, exceptional durability, and increased operational efficiency.
