Shelf Life Details Shelf life is 999 days at 73°F (23°C) in sealed containers.;Polyamides slowly absorb moisture/humidity from ambient air which may cause foaming upon melting of the product. Care should be taken to minimize moisture exposure. Keep containers sealed when not in use and store in cool, dry area. Shelf Life Temperature (°F) 73 Shelf Life (mon) 33
Best Practices for Bostik Thermogrip 6229
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. 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.
