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
Job proven one and two component adhesive systems replace mechanical fasteners/welds, increase car body stiffness, protect against pressure/corrosion while enhancing vehicle aesthetics. (Standard and custom colors are available.) Advanced compounds shorten cycle times, streamline assembly operations, reduce manufacturing space requirements and lower labor/capital expenses. Efficient, reliable, accurate application techniques range from manual/semi-automatic, single/dual cartridge gun dispensers to robotic processing equipment. Innovative formulations are designed to keep pace with the evolving requirements of automotive engineers.
