Master Bond offers special grades of epoxies, urethane modified epoxies, polysulfide modified epoxies, silicones, and UV/visible light curing compositions to meet stringent, evolving requirements of the avionic industry. Products are available to help reduce weight, increase functionality, boost durability, protect fragile/sensitive components/circuit boards, and improve safety. They consist of:
- Liquid gap fillers
- Underfills
- Die attach adhesives
- Electrically conductive bonding agents
- Conformal coatings
- Low stress adhesives
- Electrically insulative compounds
- Glob top encapsulants
- Low CTE adhesives
- EMI shielding adhesives/coatings
- UV form-in-place gasketing materials
- Lid sealing materials
- Heat sink attachment adhesives
- Snap cure adhesives
Unique formulations exhibit resistance to:
- Cryogenic conditions
- High temperature exposure
- Thermal fluctuations
- Liquids/gases
- Altitude
- Corrosion
- Shock
- Fatigue
- Chemical attacks
- Moisture
- Aging
- Abrasives
- Vibrations
Special grades meet the following requirements:
- Vertical and horizontal burn test specifications per Standard 25.853(a)
- UL94 V-1 and UL94 V-O flame retardancy
- Low outgassing per ASTM E595 requirements
- UL 746A high amp arc ignition resistance and UL94 HB for flame retardancy
- Fungus resistance per MIL-STD-810G
Additionally, it is important to note that these polymeric resins are compatible with multiple substrates, have superior mechanical properties, minimal shrinkage upon cure, excellent dimensional stability and are effective gap fillers. Low viscosity compounds have superb wetting properties and are engineered for utilization in tight tolerances. Optically clear and opaque products manifest distinctive characteristics and can provide solutions to overcome many complicated avionic dilemmas. Master Bond products can be packaged in convenient dispensers in large and small volumes.
