& nbsp; & nbsp; Three proof paint has good resistance to high and low temperatures; After curing, it forms a transparent protective film with superior insulation, moisture resistance, leakage resistance, shock resistance, dust resistance, corrosion resistance, aging resistance, corona resistance and other properties. Three proof paint has various names based on the requirements and emphasis of each region and manufacturer, such as three proof glue, moisture-proof glue, insulation glue, moisture-proof paint, protective paint, protective paint, covering glue, coating glue, waterproof glue, moisture-proof oil, three proof oil, three proof agent, protective agent, moisture-proof agent, conformal coating, conformal coating, and common coating. Its English name is Conformal Coating. The specific content is as follows.

  & nbsp; & nbsp; Chemical resistance of three proof paint



  & nbsp; & nbsp; Three proof paint has chemical resistance, and common guarantee items include salt spray resistance, acid resistance, alkali resistance, solvent resistance, and sulfur corrosion resistance. The three proof paint used on the control board of equipment applied to coastal or saline alkali areas may experience colloidal damage under the erosion of salt spray, which will definitely affect the normal operation of the equipment. For example, if the three proof paint comes into contact with acidic moisture, water vapor, or other acidic liquids and gases in the air, causing rusting and corrosion of PCB components, these phenomena indicate that the three proof paint does not have practical protective properties.

  & nbsp; & nbsp; The aging resistance of three proof paint



  & nbsp; & nbsp; The aging resistance of three proof paint commonly refers to high temperature aging. From different materials, silicone material can achieve a resistance of 200-250 ℃, polyurethane material can achieve a resistance of about 130 ℃, and acrylic material can achieve a resistance of about 130 ℃. However, a high-performance product requires a perfect combination of various components, and the material alone cannot fully reflect the true high temperature aging resistance of three proof paint. The prerequisite for the protective properties of the three proof paint is its adhesion. Therefore, after high temperature aging, the adhesion of the three proof paint does not decrease, indicating that its high temperature aging resistance meets the requirements of adhesive adhesion applications. In addition, it also has anti UV aging performance.

  & nbsp; & nbsp; Weather resistance of three proof paint



  & nbsp; & nbsp; The main technical guarantees for the weather resistance of the three proof paint include high and low temperature impact, high temperature and high humidity impact. Electronic devices coated with three proof paint, when applied to areas with relatively large temperature differences, will experience alternating high and low temperatures. This verifies that the colloidal volume expansion and contraction process will not detach from the PCB board, resulting in gaps; High temperature and high humidity are mainly used to verify the waterproof and moisture-proof properties of the three proof paint. If the waterproof and moisture-proof properties do not meet the standards, future applications may result in corrosion and mold growth of components.

  & nbsp; & nbsp; Insulation performance of three proof paint



  & nbsp; & nbsp; The insulation properties of the three proof paint on the PCB board mainly reflect that the electronic components on the PCB board will not experience leakage, short circuit and other problems during normal operation. The general three proof paint insulation technology guarantees performance items such as volume resistivity, breakdown voltage, dielectric constant, loss factor, etc. If the three proof paint still causes electrical leakage on the PCB board during application, it will lead to gel damage over time and pose a safety hazard to personnel. If it causes a short circuit, the product will be scrapped and the cost will increase< br />
