a) 2000-4000°C, 5s
b) 1000-2800°C, 1s
c) 3000-5000°C,10s
d) 1000-2800°C, 15s
Answer: b
Explanation: For Flame Treatment prior to laminating and coating, the temperature time combination is 1000-2800°C, 1s. If the temperature or time increases, the film degrades and becomes weak. If the temperature or time is less than required, the film would have a lower surface energy than required.
