Low Shrinkage Active Alignment Camera Module Adhesive

9803

Low Shrinkage Optical Camera Module Adhesive with LED and/or Heat-Cure


Dymax 9803 low shrinkage optical epoxy adhesive offers superior adhesion for common substrates used in camera modules and LiDAR assemblies, in active alignment and other optical bonding applications. The adhesive has the unique flexibility to cure in seconds with LED and/or UV/Visible light as well as low temperature heat for shadow areas. 

In addition, 9803 meets critical low-outgassing specifications making it ideal for complex optical positioning applications such as lens bonding, bonding the lens barrel to holder or bonding the holder to printed circuit boards (PCBs).

The one component epoxy requires cold shipment and cold storage (and should be kept between 1°C [34◦ F] -and 5°C [41◦F]), but does not require and not frozen shipment nor storage conditions. The epoxy has improved 85°C/85% RH resistance, exhibits less overall movement through thermal excursions and features higher viscosity and thixotropy to maintain bead shape upon dispense.

Meets NASA ASTM E595 low-outgassing specifications and follows RoHS directives 2015/863/EU.

9803 Low Shrink Adhesive For Active Alignment of Camera Modules

Dymax 9803 low-shrinkage cationic epoxy is specifically designed for the alignment of camera modules, optical components, LiDAR (Light Detection and Ranging), and other ADAS (Advanced Driver Assistance Systems) assemblies used in automotive applications. The product cures very fast primarily with LED or broad-spectrum light or UV light only. 9803 also features a low-temperature (80-85°C) heat-cure for shadow areas or where heat-only cure is preferred.
