Master Bond’s advanced line of elastomeric adhesives set the standard for today’s high-performance systems. Elastomeric adhesives are unique for their remarkable toughness and elongation properties. They have great energy-absorbing characteristics and are the solutions of choice for applications requiring resistance to exposure to vibration, shock, and impact. They are additionally preferred for use in adhering mismatched substrates exhibiting varying coefficients of thermal expansion and contraction.
High Reliability and Performance
Master Bond's elastomeric systems are designed to offer superior reliability and long-term durability. They have earned a well-deserved reputation for excellent performance upon exposure to hostile environmental conditions. Select from a wide range of systems conveniently packaged for ease of use. These compounds are available in different viscosities, cure times, chemical resistances, electrical properties, colors, etc. to best meet specific requirements. They are presently employed in applications ranging from design and production to repair, maintenance and field service.
Advantages
Some advantages of elastomeric adhesives are:
- Improved stress distribution; stresses are evenly distributed over the entire bonding area thereby minimizing high localized stress concentrations.
- Outstanding fatigue resistance of adhesively bonded joints especially to cyclic loading.
- Superior resistance to mechanical shock and vibration even upon prolonged exposure to hostile environmental conditions.
- Superior thermal resistance.
- Availability of adhesive formulations for a wide range of service conditions from as high as 600°F to cryogenic environments.
