One-component, snap-cure epoxy features high-strength properties
Suitable for a variety of applications in the electronic, aerospace and OEM industries, Master Bond EP3SP5FL is a single-component epoxy that cures in 1-2 minutes at 300degF. Since it requires heat curing, it essentially has "unlimited" working life at room temperature.
With a flowable, moderate viscosity, EP3SP5FL adheres well to a variety of substrates including metals, composites, glass, ceramics, many rubbers and plastics. It has a high tensile lap shear strength exceeding 2000psi at room temperature when bonding aluminium to aluminium. EP3SP5FL is an effective electrical insulator and it withstands thermal cycling, impact and shock. It also resists water, oils, fuels and has low shrinkage upon curing.
The service temperature range for this system is -60degF to +200degF. At ambient temperatures, EP3SP5FL has a hardness greater than 85 Shore D, but it softens above 200degF to 25-30 Shore D. This characteristic can allow the epoxy to be more readily reworkable than most other epoxy systems.
EP3SP5FL is available in syringes, ½ pints, pints and quarts containers. It has a minimum shelf life of 3 months and a maximum of 6 months in its original, unopened containers.
Master Bond EP3SP5FL is a moderate viscosity, snap cure epoxy that features the ability to be reworked. This one part system also features high physical strength properties. Follow the link to read more about Master Bond's epoxies with high tensile lap shear strength.
