LED Potting Compound, silicone sealant

Features of LED Potting Compound of Silicone

1.     Good self-leveling.

2.     Neutral, no corrosive. 

3.     Excellent adhesion properties for most materials. 

4.     Excellent electrical properties and waterproof. 

Using instruction:

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 under 0.08 MPa for 5 minutes. 

4. operate accordingly to above technical form, When under too low temperature and thick layer of sealant, we suggest customers appropriately heat the mixture to accelerate vulcanization, such as 80~100°C

Warm Tips:

1. Firstly clean the surface of the electronic devices and components which needs to be sealed/bonded with silicone rubber. (if necessary, clean or wash with anhydrous alcohol, acetone and other organic solvents.) Remember to keep the sealed parts away from the materials which contain any nitrogen (N), sulfur (S), phosphorus (P), tin (Sn), lead (Pb) salts of organic compounds and metal contacts.(Such as organic amines, phosphine-based film on the surface of the metal used for curing of amine epoxy resin, the surface of used soldering paste, dibutyl tin dilaurate, dibutyl tin oxide, Yassin acid tin, The smoke of cigarettes, fingers took smoking cigarettes, soft PVC vulcanized with sulfur rubber, some paint dried by lead naphthenate drier; Sn, Pb, Hg, Bi, As and other ionic compounds, including acetylene and multi-vinyl compounds, etc., will poisoning catalyst and resulting the rubber unvulcanized or slowly vulcanized.) Water and alcohols under the Pt-catalyzed will break Si-H bond and lose activity.The surface layer should also avoid the harmful gases, dust, poison,otherwise the silicone will be not cured or sticky evev after a long time.

 2.      the curing time is very sensitive to temperature, high temperature may speed up the curing time.
