Benefits
- High-build capability without slumping or sagging
- Can be over-coated as soon as it is dry to the touch
- Resistant to a wide variety of inorganic acids, alkalis, salts and organic media
- Machinable once cured
Applications
- Any metal surface or surface with the epoxy fillers added.
- Used in conjunction with patches, plugs and other leak repair techniques
- Used to transition aggressive changes in geometry or large defects prior to installing ECR Systems
Storage
Store indoors in cool, dry, ventilated storage at temperatures below 35°C (95°F ) in original, unopened containers. Minimum storage temperature 15.5°C (60°F)
Limitations
- Epoxy application temperature: minimum of 5°C (40°F) or less than 3°C (37°F) above dew point
- Base component should be warmed to 15.5°C to 25°C (60 to 77°F) before mixing
- Over-coating time should not exceed 3 hours
- Suitable for long-term immersion at temperatures up to 70°C (158°F) and intermittent contactwith pressurized steam up to 120°C (248°F)
- Resistant to dry heat in excess of 200°C (392°F) dependent on load
