Product introduction

LINGWO UV4020 UV curable conformal coating, also called UV three proof paint or circuit board protective adhesive, is a coating specifically designed for the protection of electronic devices and circuit boards. It is mainly used for coating and protecting electronic components such as circuit boards. UV anti adhesive can be evenly applied to the surface of electronic components through spraying, brushing, dipping, and other methods.UV curable conformal coating can quickly cure under ultraviolet irradiation, taking only a few seconds to tens of seconds. The cured adhesive can form a dense and strong protective film on the surface of the circuit board and electronic components, effectively blocking the intrusion of moisture and ensuring the normal operation of electronic devices.

Characteristics of UV curable conformal coating

(1) UV three proof adhesive has a fast curing speed

(2) UV curable conformal coating is a single-compoenent, no need to mix during use, it is very easy to apply glue or spray.

(3) Good adhesion performance of UV three proof adhesive,has good optical performance, weather resistance, and no yellowing.

(4) UV three proof adhesive is solvent-free.

Application of UV curable conformal coating

1.Circuit board protection: It is the main application scenario of UV three proof adhesive. During the use of circuit boards, they will face erosion from environmental factors such as moisture, dust, and chemicals. After applying UV three proof adhesive, a dense protective film can be formed on their surface, which can effectively improve the reliability and service life of the circuit board, ensuring the normal operation of electronic devices. For example, the circuit boards of electronic products such as mobile phones, computers, and televisions are protected with UV anti adhesive.

2.Electronic component packaging: Some environmentally sensitive electronic components, such as chips, sensors, etc., are packaged with UV three proof adhesive to prevent external environment from affecting their performance, while also enhancing their resistance to mechanical impact and vibration.

The role of applying UV curable conformal coating

(1) Protective function: UV curable conformal coating has the functions of moisture-proof, dustproof, and anti-corrosion.

(2) Electrical insulation, UV curable conformal coating has excellent insulation performance.

(3) Repackability: If a PCB circuit board malfunctions during use, it can be repaired by removing the UV anti adhesive and then reapplying it. This makes the repair of the PCB circuit board more convenient and efficient, reducing repair costs.
