Dymax is a leading manufacturer of UV/LED light-curable materials for UAV / UAS satellites, missiles, and spacecraft.
Fast light-curing materials bond and protect printed circuit boards, electronic subassemblies, and optical components in mission-critical manned and unmanned aerospace, defense, and military applications. These electronics assembly adhesives, coatings, and PCB maskants shield parts from moisture, chemicals, temperature extremes, and other environmental conditions that can cause systems to fail.
Eco-friendly, one-part materials are designed for a wide range of applications, including:
- Protection of PCBs and electronics
- Optical bonding, camera module assembly, and active alignment of lenses
- Conformal coating masking of surfaces prior to finishing processes
Light-Curable Conformal Coatings
Reliable Protection of Printed Circuit Boards and Electronics
Dymax conformal coatings protect substrates and component surfaces from the severe conditions that PCBs can be exposed to. The electronics coatings have no solvents added and cure in seconds under UV/Visible or LED light, minimizing process time and maximizing manufacturing throughput, process efficiency, and cost savings.
Designed to provide enhanced shielding, the UV cure conformal coatings protect electronic PCBs and board-level components from moisture, dust, corrosion, and other challenging environments. Formulations with secondary heat-cure capability are available for applications where shadow areas exist.
Bondable substrates include PCB materials, glass, FR-4, metal, ceramic, and glass-filled epoxy. Materials that meet NASA’s ASTM E595 low outgassing requirements for space applications and numerous other IPC and MIL-spec approvals are available.

UV Assembly Adhesives
Optical Adhesives and Epoxies for Active Alignment and Camera Module Assembly
Dymax assembly adhesives cure with UV/Visible light in seconds for rapid, precise assembly of optical component and camera module bonding. Assemble lens barrels and holders, CCD or CMOS die, rigid PCBs, or use them for active alignment applications.
These moisture and thermal-cycle-resistant UV/LED cure epoxies meet the stringent low-shrinkage and low-outgassing requirements for satellite and spacecraft avionics. Materials with a secondary heat-cure function are available to ensure a complete cure in PCB areas shadowed by light. Bondable substrates include LCP, PCB, PPS, FPC, and metallic surfaces.

SpeedMask® Maskants
Protective Conformal Coating Masking Materials
Dymax SpeedMask maskants solve a variety of PCB and electronics manufacturing challenges, including component protection during conformal coating masking operations. The materials conform to complex geometries and cure rapidly upon exposure to UV/Visible light to replace slow-curing, labor-intensive wax, tape, and lacquer masking methods. The PCB maskants are compatible with gold and copper pins and protect keep-out areas during processing.
SpeedMask maskants can be dipped, sprayed, or screen printed in one layer, making them instantly production-ready. They are easily removed after proper cure via peeling, leaving a residue-free surface with no contamination. Additionally, they are a green, eco-friendly, solvent-free, one-component alternative to two-part solvent-based maskants.
