Temperature Resistance of Various Adhesive Types

The above is a guide of temperature resistance by adhesive type.  Products usual can withstand higher temperatures for brief periods providing the joint is not unduly stressed.  High stress, poor joint design and thermal shock may cause bond failure at lower temperature. Temperature resistance is defined as the temperature at which the bond retains 40% of its str...
