Introduction
High performance VP118
VP118 is a high-performance primary adhesive with hardener CA-P2 and Al/CPP as the bonding object. It has high bonding strength, heat and humidity resistance, heat resistance and deep drawing resistance, suitable for power li-ion batteries product. Basic data：
| Item | VP118（Adhesive） | CA-P2（Hardener） |
| Solid content(%) | 18 | 50 |
| Mix ratio | 100 | 3.6 |
| Viscosity（mPa.s 25℃） | 80±30 | 20±10 |
| Expiration date（Not opened） | 180 days | 180 days |
Gerenal typeVP318
VP318 is gerenal type primary adhesive, match with hardener CA-P2.wihch is suitable for 3C li-ion battery. Basic data：
| Item | VP318（Adhesive） | CA-P2（Hardener） |
| Solid content (%) | 18 | 50 |
| Mix ratio | 100 | 3.6 |
| Viscosity（mPa.s 25℃） | 90±30 | 20±10 |
| Expiration date（Not opened） | 180 days | 180 days |
Application process
1) Coating dry weight：Suggested coating dry weight between 3~4g/m2
2) Drying temperature：Suggested drying temperature 80-100℃，according to the drying situation;
3) Compound temperature：Suggested compound temperature 80-100℃
4)Curing condition：Suggested curing temperature 55-60℃，curing time 5-7days.
Test method
1) Peeling strength: 180°peeling, machine speed 300mm/min, record the average test value
2) Corrosion resistance: Add 0.1% water to LiPF6 electrolyte, then soak 15mm wide sample in it, place for a specified time to test the peel strength
3) Heat sealing performace：cut 15mm wide sample，seal with 190℃*1s*0.4MPa，to test the heat sealing strength, and observe the equivalence.
