TORRINGTON, Conn., May 28, 2021 — Low-Shrinkage Cationic Epoxy9803 Low-Shrinkage Cationic Epoxy from Dymax Corp. is a light- and heat-curable cationic epoxy for active alignment of camera modules, optical components, lidar, and other advanced driver assistance system assemblies used in automotive applications.

9803 features low volumetric shrinkage, high glass transition, and low coefficient thermal expansion to meet rigorous active alignment requirements. It exhibits less overall movement through thermal excursions and features higher viscosity and thixotropy to maintain bead shape upon dispense. In addition, the material can be refrigerated and shipped/stored at 1 to 5 °C and not frozen. 9803 meets NASA ASTM E595 low-outgassing specifications for use in critical optical components.

Typical camera module applications include bonding the lens barrel to holder, lens bonding, and bonding the holder to printed circuit boards.
