Product Description
LiPOLY EPDM20 is a silicone-free two-part liquid caulking agent that does not volatilize low-molecu- lar-weight siloxane. With high viscosity and good adhesion, it can cure quickly at room temperature or elevated temperature. With a thermal conductivity of 2.2 W/m*K, EPDM20 provides high thermal conductivity and low thermal impedance. It is ideally suited for dispensing using the dispensing robot or by syringe.
Key Features Of LiPOLY EPDM20
- Thermal conductivity: 2.2 W/m*K
- Can be applied with dispenser
