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
