Suggested Lamination Process
Step 1:

Remove secondary liner, and then laminate
3M ARO 04N-XXX to first adherent substrate byroller at room temperature
Recommendation: roller pressure 0.1 – 0.2 MPa,roller speed 0.5 – 1 m/min

Step 2:

Remove primary liner, and then laminate
3M ARO 04N-XXX/first adherent to second
adherent by vacuum lamination
Recommendation: Vacuum condition < 50 Pa,
pressure around 0.1 – 0.2 MPa

Step 3: Autoclave process recommendation:
30-60°C/3-5kgf/cm2/20-30 min
