Magnobond 3347 (Single Component)

DESCRIPTION

Magnolia 3347 is a single component, low viscosity, epoxy material with excellent electrical properties at elevated temperatures.

SPECIAL FEATURES

Magnolia 3347 is especially formulated for the impregnation of electrical and electronic units such as coils, capacitors, transformers, and solenoids.

HANDLING

Magnolia 3347 has been formulated with epoxy chemicals and hardeners. Care should be taken to prevent contact with the skin for any length of time. In the event of skin contact, wash immediately with soap and water. In the event of contact with eyes, flush with water immediately and see a physician.
