Water Clear Polyurethane Potting & Encapsulating Compound

Description

The 20-2621 Polyurethane is a crystal clear electronic grade potting & encapsulating compound that will not yellow in outdoor applications.  This polyurethane system is semi-flexible (shore A85) and will not place excess stress on electronic components during thermal cycling.
The 20-2621 was formulated for applications that require electrical insulation, optimum clarity, environmental resistance and flexibility.  We recommend TriggerBond packaging for the 20-2621 Polyurethane.

Samples are available.
