What is the color of the silicone potting compound? What's the difference?


There are many types of silicone potting compounds, and they are divided into one-component and two-component. The construction of two-component silicone potting compounds is more troublesome. It needs to be formulated in strict accordance with the proportion before curing. Correct, it is easy to appear the phenomenon of no curing or incomplete curing during the curing stage.

What is the color of the silicone encapsulant after curing?

The appearance color of the silicone potting compound can be adjusted at will after curing. At present, there are mainly two kinds of transparent and non-transparent on the market. Non-transparent potting glue is mainly black, followed by white, gray, blue, etc.

The difference between transparent potting glue and non-transparent potting glue:

1. Transparent potting glue is classified according to resin glue and belongs to silicone rubber. The black potting glue is classified according to the resin glue and belongs to the addition type silicone. There is still a big difference between the two.

2. The transparent potting glue can be cured at room temperature, and it takes 24 hours to complete the curing phenomenon in an environment of 25 degrees. The black potting compound can be cured at room temperature or heated, and the curing time can be adjusted at will. It only takes 12 hours to cure at 25 degrees, and the higher the construction environment temperature, the shorter the curing time required.

3. The viscosity of the transparent potting glue is different from that of the black potting glue, so that the bonding strength will be different after curing.

4. The hardness of transparent potting glue is higher than that of black potting glue after curing.

5. The operating time of the two is different at 25 degrees. Clear potting takes about 40 to 120 minutes. The black potting compound has only 70 to 110 minutes of operation time at room temperature of 25 degrees. Users need to fully understand during construction, otherwise curing reaction will occur after the construction time is exceeded, and the remaining construction cannot be continued, resulting in waste.

The relevant content about silicone potting glue is the above, and users should know it when purchasing. If you don’t understand, you can consult professionals, or you can directly buy products from big brands, so that the quality is guaranteed, and you can also customize their products.
