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 20°C and can endure 300~40°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.
