Circuit board sealing adhesive, also known as electronic sealing adhesive, can be used for electronic devices or components that require packaging protection. It has stable dielectric insulation and is an effective guarantee to prevent environmental pollu

In order to protect the environment and save energy in modern electronic products, it is necessary to use a large number of materials with thermal conductivity functions, such as heat conductive potting adhesives. These potting adhesives have a series of thermophysical properties. In order to reasonably use and select functional materials, it is necessary to calculate their thermophysical properties. Therefore, it is important to understand and measure the thermophysical properties of potting adhesives, The thermophysical parameters of materials used in electronic products include thermal conductivity, temperature conductivity, specific heat, etc. The following is the operating process for testing the thermal conductivity of potting adhesives using a thermal conductivity tester in Schneider Laboratories.

The thermal conductivity of polyurethane potting adhesive is higher than that of epoxy resin potting adhesive, and its thermal conductivity can reach 2.0. It is characterized by good low temperature resistance, and can withstand low temperature - 40 ℃. Compared with other adhesives, it has the advantages of low temperature resistance and is also a soft adhesive. Like silica gel, it can not be used as a surface, nor can it withstand pressure.

Heat conduction silicone grease is commonly known as heat conduction paste, also known as heat conduction paste. Heat conduction silicone grease is a heat conduction type organic silicone compound made of organic silicone as the main raw material, adding materials with excellent heat resistance and heat conduction performance. It is used for heat conduction and heat dissipation of power amplifiers, transistors, electronic tubes, CPUs and other electronic components, thus ensuring the stability of the electrical performance of electronic instruments and meters.

Thermal conductive potting adhesive and thermal conductive silicone grease have been widely used in electronic products. They can not only efficiently dissipate heat, but also be waterproof and moisture-proof, and have good insulation. Before the protection of these thermal conductive materials, they can improve the stability, efficiency and life of electronic products.

What is platinum vulcanizing agent? Platinum vulcanizing agent is a two-component addition molding silica gel vulcanizing agent, also known as platinum water, A/B two-component. It is in the presence of catalyst, hydrogen-containing silicone oil and vinyl double bonds undergo hydrosilylation reaction, so as to achieve the purpose of cross-linking vulcanization. It is popular in the silica gel industry because of its low vulcanization temperature, high vulcanization speed and other characteristics.

These potting adhesives have a series of thermophysical properties. In order to reasonably use and select functional materials, it is necessary to calculate their thermophysical properties. Therefore, it is very important to understand and measure the thermophysical properties of potting adhesives, The thermophysical parameters of materials used in electronic products include thermal conductivity, thermal conductivity, specific heat, etc. The following is the operation process of using thermal conductivity tester in our company's laboratory to test the thermal conductivity of potting adhesive.

RTV silica gel is prepared by compounding silicone rubber, cross-linking agent, filler and other components. Generally, its molecular chain contains hydroxyl, vinyl and other active groups at both ends, and its structure is similar to silicone oil. It is a solvent-free and corrosion-free RTV silicone rubber. Long storage period and stable performance.

RTV is processed with a dispensing machine. After curing, the glue is elastic. The surface also has the properties of heat and cold resistance, aging resistance and insulation. The inside of the glue has the properties of moisture resistance, shock resistance, corona resistance and electric leakage resistance. It has excellent product adhesion, surface yellowing resistance, moisture resistance and other properties, but it will be contaminated in many ways in the outdoor. Below I list the problems that occur when the glue is dispensed with the dispenser.
