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 spraying processing is configured in the PCBA processing process to meet the environmental application requirements of customer products. Our company is equipped with one professional three proof paint spraying production line, which can automatically spray three proof paint for your PCBA. Traditional manual painting may have poor consistency, quality accidents (such as three proof paint penetrating into LCD screens, sockets, etc.), uneven thickness, and impurities mixed in with the three proof paint.
