Three proofing paint is a specially formulated coating used to protect circuit boards and related equipment from environmental erosion. Three proofing paint has good resistance to high and low temperatures

It should not be used in pure oxygen and/or enriched oxygen, and cannot be used as a sealing material for chlorine gas or other strong oxidizing substances.

Electronic and electrical products have the characteristics of small size, light weight, and high performance. The application of bonding technology in the assembly of such products can fully reflect its characteristics.

The practice of using three proof paint to protect printed circuits can be traced back to the 1960s, when the US Department of Defense developed the MIL-I-46058 specification.

If the adhesive tape is too slow to apply and there is too much residual adhesive when tearing, consider making a combination cover according to the shape, size, and position of the connector

Every manufacturer of electronic products such as mask machines, forehead temperature guns, and ventilators, as long as their products involve circuit boards, generally has a demand to purchase the three proofing paint.
