Circuit Bond Application Instructions
  1. Circuit Bond has a working pot life of 30 minutes. It should not be mixed until ready to use.
  2. To use Circuit Bond, remove the plastic clip separating the resin and hardener. Squeeze back and forth from one half of the package to the other to mix the contents.
  3. Cut a corner off the package and squeeze all the contents into a Plastic Cup. Stir the contents to ensure it is thoroughly mixed.
  4. NOTE: Circuit Bond may contain bubbles from the mixing process. If needed use a vacuum system to remove bubbles.
  5. If desired Color Agent can be mixed in with Circuit Bond to match surface colors.
  6. Apply using a Foam Swab, Micro Probe or Mixing Stick as required.
  7. Cure Circuit Bond for 24 hours at room temperature or 4 hours at 65°C (150°F).

Color Agents

Color Agent is a one part, air-drying, semi-paste ink commonly used for printing on hard surfaces, including circuit board base materials. Color Agent can be applied directly to circuit board surfaces prior to overcoating. When applied directly to a circuit board surface apply a thin coating and cure for 24 hours at room temperature or 4 hours @ 65°C (150°F).

Color Agent can be used to tint the color of 115-3302 Circuit Bond epoxy used for solder mask repair or circuit base board repair. For information on 115-3302 Circuit Bond go to:

Color Agent is supplied in 1 oz. (29 ml) collapsible metal tubes.
