9906-AA light and/or heat-curable cationic epoxy is for active alignment of camera modules, optical components, LiDAR (light detection and ranging), and other advanced driver assistance systems assemblies used in automotive apps.

Has low volumetric shrinkage, high Tg, and low coefficient thermal expansion. 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. Can be refrigerated and shipped/stored at 1°-5°C and not frozen. Meets NASA ASTM E595 low-outgassing specifications. Typical camera module apps include bonding lens barrel to holder, lens bonding, and bonding holder to printed circuit boards.
