TECHNICAL GUIDELINES for silicone coating for PCB:

1, Pls put part A and part B in separate container and stir evenly before mixing the two part together.

2, Weight Ratio: part A: part B = 1:1

3, Deaeration the mixture in vacuum pump under 0.08 MPa for 3-5 minutes.

4, The temperature influences the curing time of HY-9055#. When in too low temperature, we suggest customers appropriately heat the mixture to accelerate vulcanization. Suggested operation time and temperature. With temperature of 80~100°C, the silicone will cure in 15 minutes, while in 25°C room temperature, the silicone will cure around 8 hours.

 

Warm Tips of silicone coating for PCB : 
1.The following material may hinder the curing of the product, So pls apply after summary experiment. When necessary, pls clean the application areas.

Condensation silicone which not completely cured or organic tin compounds

Sulphur, sulfide and sulfur rubber materials.

Amine compounds as well as contains the amine materials.

Pewters solder flux.


2. Should be sealed storage.The mixture should be used up at once, avoid causing waste.

3. Silicone belongs to non-dangerous goods, but keep away from mouth and eyes.

4. When it gets stratified after a period of storage, Please mix 9060 evenly before using, it does not affect the performance
