ATTENTION
Mixing ratio for this product is 2 parts A to 1 part of B. Please
be advised that there is a misprint on our label for one of the production runs.
Protects sensitive electronic components from impact, shock, vibration, heat,
conductivity, moisture, chemicals, and visual inspection.
Features
- Non-porous, water and chemical resistant
- Extremely impact resistant (contains a form of nylon)
- Colored black, to prevent visual inspection
- Affords high security, once cured, extremely difficult to remove
- Non-conductive, an electrical insulator
- Low toxicity
- Suitable for explosion proof components (spark arresting)
- Easy and simple to mix
- Long pot life
- Can be cured in one hour at 65°C (150°F)
- This product is RoHS compliant
