Mode of Use

1. Remove dust, moisture and oil from the bonding surface .

2. Preheat with compatible heating at 100 ° C for 20 to 30 minutes is recommended.

3. Use compatible heating equipment AND the temperature should not exceed 120 ° C.

4. After sizing, it must be assembled during the opening time and kept pressurized until the initial fixation. The pressure-holding time is determined by specific experiments according to the actual product design and working conditions.

5. the glue cured due to the cooling of the machine during the sizing operation cannot be heated again.
