Two component thermal conductive silicone, cross-linked into a solid elastomer at room temperature, also known as gap filler, can be used as a heat source on PCB boards to fill irregular gaps between the surrounding chassis or heat sink. The adhesive enhancement formula of two-component thermal conductive silicone can provide both thermal conductivity and bonding functions for multiple materials simultaneously. At present, the thermal conductivity of the two-component thermal conductive silicone we provide ranges from 1.5 to 5.0 W/m · K. Easy to extrude and operate. After curing, it shows low hardness and low bonding strength. It can be used as a two-component room temperature curing thermal conductive gel, or as a two-component super soft pad that can be dispensed. The cured gel is not sticky, and is easy to remove and replace. 100% curing at room temperature without gas release during curing, can be accelerated by heating to improve production efficiency.
