Thermal conductive silicone for LED driver and electric parts use

TR-7123

Two component type Silicone was performed Excellent electrical properties and High thermal conductivity,exclusively used in LED driver, IC chips, CPU & VLSI and other electric parts to transfer the internal heat to outside region.

Especially, TR-7123 is suitable for high temperature for a long term operation.

The main feature was list as follow

1.  Excellent electrical properties

1.      High thermal conductivity

2.      High temperature working condition

3.      Chemical stability

4.      Easy performance

5.      Pass new environmental standard

Operation process

weight :    Mix TR-7123 A and TR-7123 B by ratio 100:2~5（weight ratio）Viscosity about 90,000 cps after mixed , operation time about 30 to 50 min.

Defoaming :   place the mixture in vacuum vessel，kept vacuum lower than 500 mg Hg(the lower the better) about 15~20min.

       On line:   Be careful pouring or coating this silicone to the surface, avoid occur bubble

       Harden :    Auto cured in the air.
