Gap Filler 3500LV is a two-part liquid material that reportedly delivers high thermal conductivity and low volatility for reduced outgassing. Cures at room temp. with the option of accelerated curing through the addition of heat. Delivers thermal conductivity of 3.5 W/m-K and mechanical property benefits of silicone. Low volatile content is controlled lot to lot. Is beneficial in applications that require optics remain free of lens fogging, such as automotive headlamps, stadium lighting and high-intensity LEDs.  Once cured, it is a soft material that provides protection from shock and vibration. Has ability to fill tiny gaps and voids and has zero shrinkage.
