Thermal conductive silicone for LED driver and electric parts use
TR-7145
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-7145 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-7145 A and TR-7145 B by ratio 100:2~5（weight ratio）Viscosity about 80,000 cps 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，
