Dymax develops UV/LED light-curing adhesives, conformal coatings, and maskants for electronics and optical assemblies used in unmanned systems, satellites, aerospace avionics, and defense hardware. These one-part, fast-curing light-curing solutions support tight process control and rapid stabilization of components, while meeting key aerospace standards such as ASTM E595 low outgassing, MIL-STD-883 ionic cleanliness, and additional IPC and defense-grade requirements.
Dymax one-part, eco-friendly products are used in applications such as:
- PCB protection and conformal coating
- Optical bonding and optical positioning
- Camera module assembly and active alignment of lenses
- PCB masking prior to coating or finishing
- Ruggedizing, staking, wire tacking, and encapsulation
UV/LED cure in seconds enables efficient throughput and reliable assembly of electronics exposed to vibration, thermal cycling, and vacuum environments.
Light-Cure Conformal Coatings
Reliable Protection of Aerospace & Defense Electronics Exposed to Challenging Environments
Dymax conformal coatings cure in seconds enabling rapid PCB component and board-level protection without extended oven cycles or solvent-driven processes. Fast cure reduces handling time and stabilizes delicate assemblies quickly, supporting high-throughput electronics production.
Coatings provide moisture, dust, and corrosion resistance for electronics exposed to wide temperature ranges, atmospheric cycling, and mechanical stress. Secondary heat-cure options ensure complete curing in shadowed regions. Low-outgassing formulations, such as Dymax 9771, help prevent condensable contamination in optical and vacuum environments. The MAPTIS-listed coating is suitable for spacecraft and high-altitude electronics requiring long-term stability.
The conformal coatings adhere to FR-4, glass, metal, ceramic, and other common PCB substrates and meet key aerospace and defense standards, including ASTM E595 and multiple IPC and MIL specifications.
Light-Curable Assembly Adhesives
Solutions for PCB Ruggedizing, Optical Bonding, and Precision Alignment
Dymax assembly adhesives are engineered for precise, fast assembly of optical and electronic components. These light-curing solutions offer low shrinkage, low outgassing, and excellent thermal-cycle resistance, attributes essential for satellite payloads, defense optics, and UAV imaging systems.
MAPTIS-listed low-outgassing adhesive for PCB component reinforcement
Dymax 9773provides verified ASTM E595 and MIL-STD-883 Method 5011 performance for assemblies exposed to vacuum and contamination-sensitive environments. Its high viscosity enables controlled deposit profiles for staking and ruggedizing without slumping (up to 72 hours on vertical surfaces), while the low-outgassing chemistry helps maintain optical and electrical stability in spacecraft and aerospace electronics.
Adhesives for optical positioning, camera module assembly, and active alignment
Dymax 9801 and 9803are formulated for applications where bond-line movement directly impacts focal accuracy and sensor alignment. Their low shrinkage minimizes post-cure dimensional change, preserving optical calibration, and fast UV/LED cure “locks in” alignment exactly when the system reaches its target optical position. These adhesives support lens-to-barrel bonding, sensor attachment, module reinforcement, and active alignment processes used in high-resolution imaging systems.
SpeedMask® Maskants
Reworkable PCB Maskants for Conformal Coating and Precision Processes
SpeedMask maskants
provide clean, efficient masking for PCB keep-out zones during conformal coating, soldering, and finishing processes. They conform to complex geometries and cure instantly under UV/Visible light, enabling precise masking without labor-intensive tapes, lacquers, or manual rework.
The cured maskants peel cleanly without residue after proper cure, eliminating the risk of contamination on connectors, gold fingers, or sensitive components. Single-layer application by dipping, spraying, or screen printing supports scalable automation and one-part chemistry aligns with clean manufacturing requirements common in aerospace and unmanned system production.
