2.Electrical property


Test Piece condition
Specimen size: 0.5 mm-thick sheet
Initial condition: Drying for 2 hrs at 100°C after being left at RT for 72 hrs
  • Instrument: Kikusui 875 AZ LERA CURRENT 1
  • AC Voltage applied: Increased in 0.5-KV increments in 30 seconds; the highest voltage that did not induce dielectric breakdown was recorded
  • DC Voltage applied: Started at 3 KV; increased in 0.5-KV increments in 30 seconds

3.Volume resistance


Test Piece condition
Specimen size: 0.5 mm-thick sheet
Results
Loading condition Initial(Ω-cm) After aging(Ω-cm) Aging condition
100°C 1.6 x 1015 2.2 x 1015 500hr(100°C,60°C90%)

Cycling test 1.6 x 1015 4.8 x 1015

* Data reported above is for SC608Z2. SC608LVZ2 differs only in the viscosity and solid content; the hardening characteristics are practically the same as those of SC608Z2 (within the tolerance range).

4.Surface resistance


Test Piece condition
Specimen size: Test circuit pattern (after JIS Z3197) was formed by etching a 35µm copper foil/glass-epoxy circuit board, and subsequently covered with the adhesive 0.2 mm thick (wet).
Instrument: Yokogawa HP 4329A high-resistance meter
Results
Loading condition Initial(Ω) After aging(Ω) Aging condition

5.Impact force resistance


Test Piece condition
Circular bonding: Capacitor bonded on the entire periphery of the bottom
Partial bonding: Capacitor bonding at two points on the periphery of the bottom (bonded area = half of the periphery)
  • A capacitor 6.8 g in weight was bonded onto a glass-epoxy circuit board (5 x 5 cm in size).The assembly was aged for seven days at 20°C in an atmosphere of 65% in RH. The assembly was then dropped from a height of one meter.
Results
Circular bonding Partial bonding
Joint intact in 100 times falling Joint intact in 100 times falling

6.Corrosion


Results

The product applied on a silver-plated polycarbonate board to form a 0.2-mm (wet) film did not corrode the substrate for 200 hrs at 100°C.

* Data reported above is for SC608Z2. SC608LVZ2 differs only in the viscosity and solid content; the hardening characteristics are practically the same as those of SC608Z2 (within the tolerance range).

Notes
