Thawing Process
This adhesive must be stored at (minus) –40°C (°F) or colder at all times. Storing this adhesive at temperatures warmer than (minus) –40°C (°F) may alter the adhesives’ properties and shorten its work life. DO NOT RE-FREEZE adhesive that has already been thawed!
Adhesive must reach room temperature before use. Remove syringes from freezer. Place syringes on end for thawing. See chart below for thaw time based on syringe size.
Important points
Surface Preparation
Make sure that all surface areas to be bonded are free of any contamination. If parts have been solvent cleaned make sure solvent is dried before applying adhesive.
Application
Check the work life of the adhesive, on the technical data sheet. Adhesives must be used within the work life time period. The adhesives’ properties will change (usually thicken) if it is used past the allowable work life. Apply adhesive using dispensing equipment of choice. Contact us with questions about dispensing adhesives.
Cure
Choose a Cure Option (time & temperature) from the Bondline datasheets. Preheat the oven to the temperature of the selected cure option. For optimum cure, do not deviate from the selected cure option. Be sure to allow additional time for holding fixtures to reach cure temperature. Avoid opening oven doors during cure. Large fixtures and/or multiple fixtures may require extended cure time.
Safety
Review the adhesive Material Safety Data Sheet (MSDS) before using. Refer to the MSDS in case of emergency. Always wear protective gloves and goggles while handling adhesives. Only work with adhesives in well-ventilated areas, with curing ovens vented to the outside. Bondline adhesives are for industrial use only.

Important points
Frozen Storage
Film adhesive must be stored at 5°C/-40°C or colder at all times (depending on the type of film), refer to data sheet for storage requirements. Storing this film adhesive at temperatures warmer than 5°C/-40°C may alter the adhesives properties and shorten its work life. DO NOT RE-FREEZE film adhesive that has already been thawed!
Thawing and Handling
Remove backing paper from die cut preforms only after the film has reached room temperature.
Surface Preparation
Make sure that all surface areas to be bonded are free of contamination. If parts have been solvent cleaned make sure solvent is dried before applying film adhesive.
Application
Place die cut film adhesive between cleaned parts. Apply continuous pressure of 1-20 psi during cure to avoid air pockets or voiding between adherents. Use dead weight or spring clamps. Adhesion squeeze out can be controlled by reducing clamping pressure, reducing preform thickness or cutting back the preform size by .002″ – .003″.
Cure
Choose a Cure Option (time & temperature) from the Bondline Datasheets. Preheat the oven to the temperature of the selected cure option. For optimum cure, do not deviate from the selected cure schedule. Be sure to allow additional time for holding fixtures to reach cure temperature. Avoid opening oven doors during cure. Large fixtures and/or multiple fixtures may require extended cure time.
Non-weight Bonding
In some cases, pressure bonding is not possible. Therefore, one recommended procedure is to place the adherends , with the film adhesive (liners removed) between them , on a hot plate for 1 to 2 minutes, until the adhesive film becomes tacky or slightly melted. Scrub the two adherends together in a back and forth motion, until intimate contact occurs (Co-planer alignment) and air is removed from the adhesive bondline. Put into a box oven to fully cure (preferably a convection box oven).
Safety
Review the adhesive Material Safety Data Sheet (MSDS) before using. Refer to the MSDS in case of emergency. Always wear protective gloves and goggles while handling adhesives. Only work with adhesives in well-ventilated areas, with curing ovens vented to the outside. Bondline adhesives are for industrial use only.
