Epoxies, Etc's new electronic grade 20-2620 is a two component Polyurethane compound designed for applications requiring "water like" clarity. This room temperature curing system provides excellent environmental protection and will not yellow over time.
20-2620 is semi-flexible and will not place excess stress on electronic components. It also has a low viscosity, which facilitates easy flow and penetration into difficult areas.
This product has a convenient one to one mix ratio and is considered DOT non-hazardous.
