One component “snap cure” epoxy adhesive with paste viscosity

Key Features

  • High bond strength
  • Convenient handling
  • Cures in 1-2 minutes at 300°F
  • More readily repairable than most epoxies

Product Description

Master Bond EP3SP5FL-ND2 is a special epoxy adhesive that requires no mixing, offers an unsurpassed curing speed of 1-2 minutes at 300°F and a very good performance profile. It is a paste viscosity with minimal flow upon curing that is easy to apply. Since it requires curing at 300°F, it essentially has unlimited working life at room temperature. It will bond well to a variety of substrates including metals, composites, glass, ceramics, many rubbers and plastics. EP3SP5FL-ND2 has very good tensile lap shear strength when bonding aluminum to aluminum along with other potent physical strength properties. It resists water, oils and fuels quite well. Other desirable features include low shrinkage upon curing and highly effective electrical insulation values. Also, it stands up briskly to thermal cycling as well as impact and shock. The service temperature range for this system is -60°F to +200°F. Most notably, EP3SP5FL-ND2 softens markedly above 200°F and this characteristic can allow the epoxy to be more readily reworkable than most other epoxy type systems. This system is amber in color. EP3SP5FL-ND2 is considered a “snap cure” type epoxy system and can be used in a variety of applications in the aerospace, electronics and specialty OEM industries, among others, particularly when ultra fast curing, repairability and a paste viscosity are desirable features.
