1. Product Overview

BERGQUIST GAP FILLER TGF 1000 is a thermally conductive, liquid gap filler designed for fragile and low-stress applications. It is a two-component system that cures at room or elevated temperatures, forming a soft, thermally conductive, form-in-place elastomer.

Key Features & Benefits

✔ Thermal Conductivity: 1.0 W/m-K
✔ Ultra-conforming with minimal stress during application
✔ Room temperature or accelerated cure schedules
✔ 100% solids with no cure by-products
✔ Excellent mechanical and chemical stability across a wide temperature range

2. Applications

🔹 Automotive electronics (HEV, NEV, battery applications)
🔹 Computers & peripherals
🔹 Heat-generating semiconductors to heat sinks
🔹 Telecommunications
🔹 Vibration dampening with thermal conductivity
