Dymax OP-18 is a new, opto-mechanical adhesive for nonpermanent fixturing. It is designed to cure in seconds upon exposure to UV light and fixture assembled parts temporarily. Upon completion of the process, the adhesive can be easily peeled away. Parts can be adjusted after the adhesive is dispensed to obtain precise alignment, since OP-18 only cures upon exposure to UV/visible light. Instant immobilization occurs during curing.
