Test Piece Condition

Substrate:Stainless steel plate (SUS304)
Tape width:20mm
Bonding condition:One stroke with 2-kg roller
Measuring condition:23±5°C 60%±20%RH
Peeling speed:300mm/min

[A test specimen was left at RT for one hour, and a heat cycle test was conducted under the following conditions (-20°C x 3 hours ⇔ 25°C x 15 min ⇔ 70°C x 3 hours ⇔ 25°C x 15 min). These conditions comprise one cycle. One to three cycles were conducted for each specimen]
