Mixing
It is highly recommended that either meter mix equipment or cartridges with static mix nozzles be used to properly ratio and dispense the adhesive. Heat buildup during and after mixing is normal.
Applying
Bonding surfaces should be clean, dry, and free of contamination. Extensive surface preparation is not required for Fusionbond® 373 and good bonds can be formed on most substrates after a solvent wipe. To assure maximum bond strength, surfaces must be mated within the adhesive's open time. Use enough material to completely fill the joint when parts are clamped.
CuringParts should remain undisturbed during the interval between the adhesive’s open time and fixture time. After the fixture time is achieved the material has reached handling strength. Cure temperatures below room temperature (70ºF to 75ºF) may slow the fixturing time. Temperatures above room temperature will shorten the open time and the fixturing time.
Clean UpIt is important to clean up excess adhesive from the work area and application equipment before it cures. Use Hernon® EF® Cleaner 62 for removing uncured adhesive. Fusionbond 373 is flammable. Keep containers tightly closed after use. Keep away from heat, sparks, and open flames.

This product is not recommended for use in pure oxygen and/or oxygen rich systems and should not be selected as a sealant for strong oxidizing materials. For safe handling information on this product, consult the Safety Data Sheet (SDS).
Storage & Handling
- Storage
Fusionbond® 373 should be stored in a cool, dry location in unopened containers at a temperature between 45ºF and 75ºF (7ºC and 24ºC) unless otherwise labeled. Shelf life can be extended by refrigeration at 45ºF to 55ºF (7ºC to 13ºC). To prevent contamination of unused material, do not return any material to its original container.
