Instructions for Use:
- Before use, thaw the product at room temperature for 2–3 hours. Ensure the syringe is placed vertically during thawing. Keep the container airtight until it reaches room temperature.
-
Ensure the surface to be bonded is clean and free of contaminants.
-
Cure time may vary based on the actual part geometry, material volume, and equipment. It is recommended that the test be done on actual parts and equipment.
-
For large-scale applications, consider a staged curing process: start with a lower temperature pre-cure, followed by a full cure at a higher temperature to effectively manage heat release.
-
Cool down gradually after curing to minimize thermal stress.
-
The epoxy cannot be refrozen once exposed to room temperature.
