- Application Instructions
- H.B. Fuller EV Bond 720 is designed to be used with heated platen-style melting machine that transfers material from pails or drums to a nozzle enough to form a bead and dispense into the housing.
- Substrate surface must be clean, dry, and free from oils and dust.
- Non-polar substrates must be surface treated (e.g. plasma treated) prior to adhesive application.
- If the equipment is to be shut down for extended periods of time, we suggest purging the system with H.B. Fuller Swift®Clean 9037.

Technical Details & Test Data
- Curing Profile
Under standard conditions (23°C, 50% RH), full cure will take approximately 14 days. Any deviation from standard conditions will change the cure rate. Additionally, cure rates and completeness of cure will vary with adhesive thickness and the substrate's moisture permeability.
