Key Benefits of Structural Epoxy Adhesives for Automotive Applications

Master Bond structural adhesives feature excellent adhesion to a wide range of substrates including aluminum, steel, magnesium and composites. Other advantages include:

  • Uniform stress distribution and larger stress bearing areas
  • Gap filling
  • Solvent free
  • Contagious contact between substrates promotes load bearing and sealing properties
  • Lower cost and increased productivity
  • Wide service temperature range
  • Reduces vibration and improves acoustics
  • Improved energy efficiency through weight reduction
  • Outstanding fatigue, mechanical shock and thermal shock resistance
  • Can bond surfaces with different coefficients of expansion and contraction
  • Superior moisture and chemical resistance
  • Easy automatable application
