Technical Details & Test Data
- Users Report
High Resistance Even in High Humidity
Used to seal thermocouples, electric heaters and critical electronic components for use in high humidity environments. Tests show less than 10% of the moisture transmission of silicones or competitive epoxies.
Proven in Instrumentation Applications
Used for fabrication of end seals and installation of thermocouples, pressure, strain gages and flow measuring instruments.
Excellent Corrosion Resistance
Used to repair glass lined tanks for use in 36% Hydrochloric, 29% Phosphoric, 65% Sulfuric and 70% Nitric Acids, 25% Caustic, 30% Chrome Oxide solutions. Competitive epoxies disintegrated in less than 24 hours.
Bonds Carbon to Steel and Remains in use for 5 years
Used to bond carbon blocks to steel for bearings in a rotating kiln at 300°F. Bonds brake pads.
Fast Cures
Independent tests have shown 95% cure in 15 minutes at 200ºF and 100% cure in 5 minutes at 250ºF, enabling high speed production applications.
