( 353ND ) Epo-Tek 353ND Epoxy -

Epo-Tek 353ND is a two component, heat curing epoxy designed for high temperature applications. It becomes a favorite epoxy of many fiber optic users.

353ND will perform continuously at 200°C and can endure 300~400°C for several minutes. It has excellent resistance to many types of solvents and chemicals and is ideal for bonding fiber optics, metals, glass, ceramics and most plastics.

353ND remains liquid until heat is applied. It can be applied by brush, dipping, pouring or mechanical dispensing techniques.

This item comes in a 8oz kit with a shelf life of 1 year when stored at room temperature. Refrigeration is not required.
