SE600AB Two-Component Thermal Gel 6.0 W/mK
SE600AB is a flexible two-component silicone resin-based thermally conductive gap filler developed for small-gap tolerance applications between heat-generating components and heat sinks or housings. After mixing and curing, it forms a soft elastomer that maintains interface thickness, provides reliable shock absorption, and improves thermal contact between mating surfaces.
With thermal conductivity of 6.0 W/m·K, low thermal impedance, and superior extrusion properties, SE600AB helps reduce contact thermal resistance and enhances heat dissipation efficiency in electronic assemblies. It is suitable for projects that require controlled dispensing, good flexibility after curing, and reliable insulation performance.
