Henkel Develops Silicone-free Liquid Thermal Gap Filler with Excellent Dielectric Strength for High Voltage Applications
Henkel today announced the commercial launch of Bergquist Gap Filler TGF 3000SF, the latest in the company’s line of silicone-free thermal interface materials (TIMs).
Henkel today announced the commercial launch of Bergquist Gap Filler TGF 3000SF, the latest in the company’s line of silicone-free thermal interface materials (TIMs). With significantly higher thermal conductivity than any previous silicone-free liquid formulation in its portfolio and delivering impressive dielectric strength, Henkel’s new material extends wider market opportunities and production flexibility to manufacturing operations that require avoidance of silicone outgassing.

Henkel Director of Market Strategy for Power and Industrial Automation, Justin Kolbe, explains that the challenges associated with silicone contamination are well-known and silicone-sensitive devices more prevalent. “As sensors and optical components become prolific within industrial applications, and products such as drives and robotics need to be manufactured for multi-purpose use, sourcing components that pose no risk of silicone contamination is a central reliability criterion,” he says. “At the same time, power densities are increasing, footprints are shrinking and controlling for higher thermal loads and voltages while facilitating high-volume, cost-efficient production remains priorities. This is not an easy balance to strike, but one that Bergquist Gap Filler TGF 3000SF achieves.”
A liquid, two-part, 3.0 W/m-K silicone-free TIM, Bergquist Gap Filler TGF 3000SF offers high-reliability performance for a variety of applications where silicone sensitivity is a concern. These include industrial automation systems; power conversion technologies such as motor drives and power supplies; automotive infrastructure EV charging devices; and, computers and peripherals, to name a few. With high dielectric strength at >10 kV/mm and good volume resistivity, Bergquist Gap Filler TGF 3000SF is suitable for higher voltage applications, while also providing high-reliability thermal performance at operating temperatures ranging from -40° C to 100° C. Exhibiting extremely low assembly stress, the liquid TIM is ideal for use with sensitive components and/or printed circuit boards with intricate architectures.
Productivity is also a central attribute of Bergquist Gap Filler TGF 3000SF. The silicone-free liquid TIM is conducive to mass production environments where fast dispensing is necessary to achieve high UPH objectives; it dispenses at a rate of 1.5 cc/sec. With a 1:1 mixing ratio, the material can be stored at room temperature and is easily processed.
“The silicone-free attributes of this product make it viable for use in almost any environment,” comments Kolbe, noting the opportunity for customers to simplify supply chains through inventory simplification. “This, in addition to its cost-competitiveness and process adaptability, puts Bergquist Gap Filler TGF 3000SF in a distinctive class.”
Though only recently commercialized, the product is already specified for several customer programs and outcomes have been extremely positive. To learn more about Bergquist Gap Filler TGF 3000SF, visit the product page.
