Fasto TG260 – High Thermal Conductivity Silicone Paste

Fasto TG260 – High Thermal Conductivity Silicone Paste

Fasto TG260 is a one-part, high-performance, silicone-based non-curing thermally conductive paste formulated for applications requiring efficient and continuous heat transfer at elevated temperatures. With its higher thermal conductivity, Fasto TG260 effectively fills microscopic air gaps between heat-generating components and heat-dissipating surfaces, ensuring rapid heat dissipation and improved system reliability.

Its thick, smooth paste consistency allows easy application using a spatula, forming a uniform thermal interface without curing or hardening over time. Fasto TG260 also provides excellent electrical insulation, weather resistance, and stable performance under continuous and intermittent high-temperature conditions, making it suitable for demanding electronic and electrical assemblies.
