High heat resistance, high humidity resistance, flexible epoxy adhesive St8838
A one-component black epoxy that balances high temperature and humidity resistance with flexibility, suitable for jet dispensing, reflow, and low halogen, ideal for bonding/protecting electronic components.
One-component black epoxy that balances high temperature and humidity resistance with flexibility. With a Shore hardness of D15 to D25, it is flexible yet strong against heat and high temperature and humidity. It has proven resistance to temperature cycle tests from -40°C to 105°C and high temperature and humidity tests at 85°C and 85% humidity. Work life is 72 hours, and it has excellent viscosity stability. It is suitable for bonding/protecting electronic components with reflow compatibility and low halogen content.
