Best Practices for Bostik Thermogrip 2124
All surfaces should be clean and free of contaminants. If necessary, clean surfaces with solvent.
Apply the adhesive to the more difficult-to-bond surface. In general, hard, smooth surfaces are more difficult to bond than rough, porous surfaces. “Open-time” varies depending on application temperature, amount of adhesive applied, type of substrate and ambient temperature conditions. Mate the surfaces to be bonded as quickly as possible after adhesive has been applied for optimum bond strength. Use firmest pressure practical for object being bonded. Do not move or adjust surfaces after contact has been made, as inferior bond strength will result. Bonding some metals is enhanced by pre-warming the surfaces. Pre-warm up to 200°F (95°C) for optimum effect. Because of its excellent adhesion properties, 2124 can be difficult to run in some glue guns, especially after idle durations greater than 20 minutes. It is recommended to run 2124 in guns having flexible feeding tubes or semi-rigid Teflon® feeding tubes, and to keep gun idling times as short as possible. Typically, a properly formed hot melt adhesive bond will achieve 50% of its strength after 1 minute, 75% after 1 hour, and 100% after 1 day.
