BERGQUIST GAP FILLER TGF 3500LVO is an ultra-conforming, two-component liquid gap filler designed for sensitive, low-stress applications across aerospace, aviation, defence, OEM, and MRO environments. Its low volatility and excellent wet-out make it suitable for assemblies requiring minimal outgassing and reduced mechanical stress, including avionics, optical systems, cabin electronics, and other mission-critical aerospace applications.
The material provides infinite thickness variability without introducing excess stress to components and cures at room temperature, with the option to accelerate the process using heat. Offering solids with no cure by-products, it supports clean, stable performance in silicone-sensitive environments. With a thermal conductivity of 3.5 W/m-K and exceptional conformability, TGF 3500LVO delivers efficient heat dissipation while protecting delicate electronics.
