B-Stage Epoxy Film
B-Stage Epoxy Film
B-Stage epoxy film is thermosetting resins with high cohesive strength and excellent adhesion to metals, ceramics, glass, rubber, and some plastics. They are generally rigid and have excellent chemical resistance. Epoxy film enables clean, consistent bond lines and manufacturing that eliminates dispensing of liquids.

B-Stage Application Process
Step 1: Remove rolls or cut parts from frozen storage area and rolls or parts from “clamshell” packaging
Step 2: Allow parts to acclimatize to ambient temperature for 1-2 hrs.
Step 3: Remove release paper liner from 1 side
Step 4:Apply adhesive film to desired part and press firmly and expose to recommended heat and pressure conditions for appropriate time
