How to use silicone potting glue and precautions

The two-component black potting glue is a special glue for electronic components. It can be used for potting circuit boards and components. It will not corrode the circuits of various materials and can play a protective role.

Silicone potting adhesives are used in a wide range of fields, such as potting and sealing of power electronic components that require flame retardancy and heat conduction, and high-voltage potting of components; potting and waterproofing of new energy electric vehicle power batteries Heat conduction potting for power supply, lightning protection module, HID potting; potting for heating electronic components under working conditions, such as converters, inverters, sensors, electronic control units, etc.; precision mechanical parts, instrumentation parts Shockproof protection, potting protection of small electrical appliances; high temperature resistance, heat conduction and flame retardant potting of small appliances and household appliance control boards.

The two-component black potting adhesive has the characteristics of curing at room temperature, and it only takes 24 hours to complete the complete curing at room temperature. After curing, it has an elastic volume, which not only has adhesive properties, but also insulation properties and aging resistance.
At the same time, the two-component black potting adhesive has good performance of high and low temperature resistance after curing, and there will be no performance change between -50 degrees and 200 degrees. It can be used in outdoor electronics or electrical appliances in harsh weather. Such as display screens, bulb lamps and led lamps, etc.

The ratio of the two-component black potting glue is 10:1, and the ratio must be strictly followed when mixing, and this ratio cannot be changed without authorization. If the ratio is changed by yourself, it will lead to failure to cure or incomplete curing. Such potting glue is used in electrical appliance manufacturing, which has great potential safety hazards.

The color of the two-component black potting adhesive can be adjusted at will, and can be adjusted into white, gray, or blue according to needs. However, users cannot make adjustments by themselves. If they want to adjust colors, they must be adjusted by the factory.

Silicone potting adhesive can be divided into two types: condensation type two-component potting adhesive and addition type two-component potting adhesive. The ratio of potting glue is 1:1, which can be cured at room temperature or heated.

Use according to the required amount, according to the weight ratio A:B=(1:1 or 100:10) as it is prepared and used. When mixing, please add the rubber material and stir well, after defoaming (vacuum or standing), the potting construction can be carried out. Before potting, please clean the dust, oil, water and other impurities on the surface of the components, and keep them dry.

During the production process, ventilation and personal protection should be strengthened. Open flames are strictly prohibited and kept away from fire and heat sources. When handling, pack and handle with care, the packaging cover should be covered in time, and the used tools and equipment should be cleaned in time for the next use. Do not let the potting compound come into contact with nitrogen, sulfur, phosphorus-containing compounds and metal organic acids during use, otherwise the compound will not be cured or cured incompletely. The operating time of the potting compound is related to the curing time and temperature, the higher the temperature, the shorter the operating time. The performance parameters of the test should be carried out at least 3 days after the glue is completely cured, and the relevant values ​​reach a stable value at this time.
