Tri-Protection Glue is a specially formulated material used to protect circuit boards and their associated equipment from environmental pollution. Three anti-adhesive has good resistance to high and low temperature performance; after curing, it forms a transparent protective film, which has excellent insulation, moisture, leakage, shock, dust, corrosion, aging, corona and other properties. The next small series for everyone to introduce the role of three anti-plastic and three anti-adhesive use.
The role of three anti-adhesive
Tri-Protection Glue is a specially formulated coating that is used to protect circuit boards and related equipment from environmental damage, thereby increasing and extending its useful life and ensuring the safety and reliability of use. Under normal use and storage conditions, such as chemical, vibration, high dust, salt spray, humidity, and high temperature, the circuit board may be corroded, softened, deformed, and mildewed, resulting in failure of the circuit board circuit.
The three anti-adhesives are applied to the outer surface of the circuit board to form a layer of three-protective maintenance film (three anti-moisture, anti-salt, and anti-mold) shocks such as chemical substances (eg, fuel, coolant, etc.). Moisture, salt spray, moisture, and high temperatures protect the circuit from damage. Under these conditions, circuit boards may be corroded, molds grow, and short-circuits may occur. Circuits that do not use the three-protective adhesives may fail, thereby improving the reliability of the circuit board, increasing its safety factor, and ensuring its service life. In addition, because the three anti-gels can prevent leakage, they allow higher power and closer printed board spacing, which can meet the miniaturization of components.
The use of three anti-adhesive
1, civilian and commercial use: washing machines, dishwashers, bathroom products, air conditioners, desiccants, computers, anti-theft, fire alarm devices.
2. Automobile industry: The use of three anti-adhesives can ensure the basic requirements for long-term reliability of automotive electronic devices.
3. Aerospace: Because of the special nature of the environment, the requirements for aerospace on electronic equipment are particularly stringent. In order to maintain good circuit performance, the pressure stability of three anti-gels is widely used.
4. Navigation: The salt content in seawater will cause damage to the electrical circuits of the ship's equipment. The use of the three-phase period can protect the water surface equipment and underwater equipment to the maximum.
5, medical: three anti-adhesive can also protect electronic equipment from being eroded by chemical agents, ensuring the continuous stability of electronic equipment.
Three anti-adhesive features
Three anti-gel is a one-component, low-viscosity silicone resin. Easy to use, brush or dip coating, good adhesion to various circuit boards. Has good temperature resistance in the (-60 °C -200 °C) range of cold and heat aging performance remains good; after curing, it forms a transparent, elastic, glossy protective film: excellent dielectric, waterproof, shock-resistant Sex, weather resistance, stain resistance, UV resistance, and moisture-proof insulation.
The three anti-adhesives have prominent "moisture-proof", "anti-salt spray" and "insulation" properties; the film still retains its good dielectric properties in a humid environment; it has strong resistance to oxidation, aging, and resistance Corrosion of many different concentrations of acid, alkali and salt, curing at room temperature or low temperature, the film is dense and bright, no cracking, and decorative.
Editor's summary: The role of the three anti-adhesives and the use of the three anti-adhesives were introduced here, and we hope to help everyone. If you want to know more related information, you can pay attention to this website information.
