Heat Curable Fiber Optic Epoxy
Unique design of epoxies with good bonding strength and optical matching to allow optimum signal transition is always desired in this industry. The heat curable epoxies for fiber optic components that have adhesion on glass, metal, ceramic and most plastic substrates provide excellent thermal and moisture resistance.

Application:
Sealing fibers into ferrules, bonding optical fibers into connectors or/and ferrules, potting fiber bundles, V-groove array, chip bonding such as fiber media converters and transceiver modules assemblies

Dual Cure UV Fiber Optic Adhesive
Fast cure, high viscosity UV-curable epoxy system. Excellent flexibility, good toughness and good adhesion to  a variety of substrates including metals and plastics. It has low odor and low skin and eye irritation potential. It does not contain volatiles and is very suitable for fiber optic applications. It is not inhibited by oxygen during UV cure, has low shrinkage, high gloss and good resistance to yellowing. The thixotropy has been adjusted to control excessive overflow. 

Application:
Sealing fibers into ferrules, bonding optical fibers into connectors or/and ferrules, potting fiber bundles, V-groove array, chip bonding such as fiber media converters and transceiver modules assemblies
