FEATURES AND BENEFITS
● Thermal Conductivity: 2.0 W/m-K

● 100% solids – no cure by-products
● Excellent low and high temperature mechanical and chemical stability
BERGQUIST GAP FILLER TGF 2000 is a high performance, thermally conductive, liquid gap filling material supplied as a two-component, room or elevated temperature curing system. The material provides a balance of cured material properties and good compression set (memory). The result is a soft, thermally conductive, form-in-place elastomer ideal for coupling “hot” electronic components mounted on PC boards with an adjacent metal case or heat sink. Before cure, BERGQUIST GAP FILLER TGF 2000 flows under pressure like a grease. After cure, it does not pump from the interface as a result of thermal cycling and is dry to the touch.
TYPICAL APPLICATIONS
● Automotive electronics (HEV, NEV, batteries)
● Telecommunications
● Computer and peripherals
● Thermally conductive vibration dampening
● Between any heat-generating semiconductor and a heat
sink
