TB2217L is a one component epoxy resin, which has been specifically developed for surface mount assembly. This adhesive is designed to keep the components in position during both placement and the wave soldering process. It works well in fast application processes due to its low temperature curing schedules (Heat curing initiated at just 80ºC) and is ideal for temperature-sensitive components. TB2217L produces an excellent deposited dot, excellent tack strength, and after curing exceptional bond strength.
Its properties are designed for ease of handling to enable use in automated assembly by either syringe or screen print application.
