3M™ Scotch-Weld™ Hi-Temp Sealer EC-1137 is an inorganic sodium silicate compound designed to protect metal surfaces. It can withstand extremely high temperatures and is often used in applications that require short term protection and exposure.
3M™ Scotch-Weld™ Hi-Temp Sealer EC-1137 is an inorganic sodium silicate with the consistency of a heavy paste. It features good adhesion and overlap shear strength when applied to cold rolled steel, stainless steel and aluminum surfaces. It allows sealing of exterior surfaces of aircraft or other applications where high-temperature conditions might require protection. The Hi-Temp Sealer is designed to perform at extremely high temperatures, and can even withstand short-term exposure to temperatures as high as 2000°F/1093°C. To ensure ease of application and control the heavy paste can be easily applied with a spatula or putty knife. This helps reduce waste and increases the precision of application when dispensed on the areas requiring protection.
