Electrolube^® LGF400 Liquid Gap Filler

Electrolube® LGF400 is a thermal interface material engineered for easy processing. This silicone-based liquid gap filler features a two-component, cure-in-place formulation. With a high thermal conductivity of 4 W/m-K, LGF400 ensures superior heat transfer between mating surfaces, helping to prevent device overheating.

Thanks to its shear-thinning nature, Electrolube® LGF400 dispenses easily with precision and remains in place without slumping. Once dispensed, LGF400 conforms closely to mating surfaces, effectively filling air gaps and providing excellent wet-out. Curing can occur at room temperature or be accelerated with heat, producing a soft, fully cured elastomer that stays securely in place, preventing pump-out and ensuring long-term reliability in critical applications.
