Fusionbond® 372


Fusionbond® 372 is a two-component, room temperature curing, 1:1 ratio, methacrylate adhesive system. Fusionbond® 372 is formulated to provide fixturing strength within 10 to 15 minutes. This adhesive is Halogen-free. Fusionbond® 372 forms resilient bonds and maintains its strength over a wide range of temperatures. Fusionbond® 372 is suitable for bonding a variety of substrates with a minimum of surface preparation.

Recommended substrates: PVC, acrylic, ABS, stainless steel, and some types of fiberglass. This product is NOT recommended for use in pure oxygen and/or oxygen-rich systems and should not be selected as a sealant for chlorine or other strong oxidizing materials. For safe handling information on this product, consult the Material Safety Data Sheet, (MSDS).

Handling and Application: 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 ® 372 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 joints when parts are clamped.

Curing: Parts 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-Up: It 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® 372 is flammable. Keep containers tightly closed after use. Keep away from heat, sparks, and open flames.

Storage: Fusionbond® 372 should be stored in a cool, dry location in unopened containers at a temperature between 45ºF and 85ºF 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.

Grade: 372
