To ensure reliable thermal interface for heat management, GAP FILLER 3500LV can fill tiny gaps and voids and offers zero shrinkage. This 2-part material, suited for use in applications that require optics to remain free of lens fogging, addresses thermal requirements of next-generation product designs, produces minimal outgassing, and cures at room temperature. Accelerated curing can be achieved with additional heat. Once cured, soft material also provides protection from shock and vibration.
