Product Description
1:1 Electronic silicone rubber is a two-component silicone rubber composed of Part A and Part B. It is fluidity and sticky before curing. After curing, it can bond and seal electronic components. It has the functions of waterproof, moisture-proof, dust-proof, insulation, thermal conductivity, flame retardant, confidentiality, corrosion-proof, temperature-proof and shock-proof. Ideal Materials for Electronic Products.
More details

1.Follow EU ROHS 2.No corrosive effect 3.High waterproof level 4.Excellent adhesion strength 5.Low viscosity,good fluidity 6.Flexibility allows for easy removal 7.Significant extending the life of electronic parts 8.Good temperature and moisture endurance 9.Outstanding isolation and chemical resistance
Please rean the directions carefully for proper using: 1.A small-scale test for compatibility before using on your project is recommended. 2.Weigh Part A and Part B separately in correct proportion(by weigh not volume). 3.Use the clean mixing container and tool to mix them thoroughly. 4.Kppe the working in a clean container for the surface of final products not polluted by contaminants. 5.The primer can not be directly mixed with the silicone,if the primer is necessary,please keep it to be dry,and then make potting. 6.The platinum cured electronic potting silicone(1A:1B) may be inhibited by certain su7bstances such as phosphorus,ammonium,chlorine,carboxylic acid,thiol,hydroxyl and etc. 7.The best thickness of the clear cured electronic potting silicone(10A:1B) is 1-3mm,otherwise itis hard to cure.

1.The working time of RTV2 silicone rubber indicates how long the material will remain fluid at 23℃~25℃,However,work should be carried out in the shortest time ,because viscosity increases with me. 
2.The curing time of tin cured potting silicone rubber is related to the temperature and the thickness of the product,but platinum cured potting silicone rubber only affected by temperature.
Step 1:Weigh Part A and Part B by the accurate ratio 
Step 2:Mix Part A with Part B and stir thoroughly 
Step 3:Pour the mixture into the electronic components 
Step 4:Cure in no-dust condition at room temperature(the warmer temperature,the faster curing)

  1. How to make the silicone mould to use longer time?

--The best way is:

1)Please choose the right liquid silicone according to your applications.

2)Don’t use too much oil in mold making, because it can make the silicone mould become soft.

3)Silicone mould can be used for a long time , it’s better to wait 2 hours after the mould completely cured.
