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.
