Thermal conductive adhesive: a new type of special adhesive based on metal powder with a high temperature range of use

1、 Definition and classification of thermal conductive adhesive
1. Thermal conductive adhesive: It is a special adhesive that uses metal powder as the base material, adds various additives, and is mixed and stirred before being coated on the surface of the parts to be connected. By heating or cooling, the two materials to be connected undergo physical and chemical changes, thereby achieving permanent bonding between the two. Due to the fact that the substrate of this adhesive is metal powder, it is also known as "metal universal adhesive".
2. Thermal conductive adhesive: It is a new type of special adhesive based on metal powder and has a high temperature range of use. Its application areas include aluminum magnesium alloys in the automotive, motorcycle, aerospace industries, steel and copper, etc; Carbon steel and stainless steel in the mechanical manufacturing industry; Aluminum silicon alloy and copper aluminum alloy in the electrical and electronic industry; High temperature reactors in the chemical industry; Construction industry; Packaging and printing industry; Healthcare; sports goods; Daily necessities; Toys; Arts and Crafts; Food processing; Agriculture, forestry; Oil, coal, and natural gas extraction; And military equipment, etc.
II Introduction to Thermal Conductive Adhesive Properties
1. High fluidity: High viscosity can be achieved at room temperature and maintained for a long time. Good fluidity can still be maintained when the temperature is below 10 ° C. Therefore, it is particularly suitable for rapid curing, such as injection molding of mobile phone casings, hot pressing of home appliance casings, and molding of footwear products. In addition, this product is also used in situations where high fluidity is required. For example: filling of plastic hoses, filling of cosmetic pipelines, pipeline sealing, etc.
2. Temperature resistance: Can withstand high temperatures up to 300 ° C. It can also ensure a certain degree of flexibility in low-temperature environments. At the same time, it also has excellent cold resistance and can be used for a long time in the temperature range of -20~50 ° C.
3. UV resistance: It has excellent UV resistance performance.
4. Low shrinkage: The shrinkage after curing is small and does not crack.
5. Corrosion resistance: It has good resistance to acid, alkali, salt, oil, water corrosion, especially to seawater, oils, fatty alcohols, ketones, esters, aromatic compounds, chlorinated aromatic hydrocarbons, stannous chloride, trichloroethylene, etc.
6. Electrical insulation: has good dielectric properties.
7. Environmental Protection: Non polluting.
8. Non toxic: Compliant with EU RoHS standards, safe and environmentally friendly.
9. Easy to operate: No need for a drying oven, self drying at room temperature, and can be applied and dried immediately.

1. Efficient: Thermal bonding technology can quickly and effectively transfer heat to the target surface, thereby improving the heat dissipation efficiency of the equipment.

2. Stability: Thermal bonding technology can effectively keep heat on the target surface, thereby improving the stability of the equipment.

3. Economy: Thermal bonding technology does not require a large amount of energy investment, so the cost is relatively low.

4. Reliability: Thermal bonding technology can effectively keep heat on the target surface, thereby improving the heat dissipation efficiency of the equipment and ensuring its stability.

5. High reliability: Thermal bonding technology has high reliability and can withstand repeated use and external loads, thereby improving the service life of equipment.
