Conformal paint is a kind of protective paint with a special formula, and UV conformal paint is an important type of conformal paint. With its unique curing method and excellent performance, it is widely used in electronic device circuit boards and related components. As UV conformal paint receives more attention, many people begin to want to understand its advantages and disadvantages.

Nufil is an innovative enterprise that has been deeply involved in the field of electronic adhesives for more than ten years, and has a good reputation in the industry with its self-developed conformal paint products and adhesive technology solutions. Based on years of research and understanding of UV conformal coatings, Nu Fei leads everyone to deeply discuss the advantages and disadvantages of UV conformal coatings, helping everyone to understand this material more comprehensively. UV conformal coatings have the advantages of fast curing, high adhesion, good protective performance, good environmental protection, high transparency and easy operation, and have a wide range of application prospects in the field of electronic equipment protection. Among them, rapid curing can greatly improve production efficiency; High adhesion provides reliable protection for different materials; Protective properties include waterproof and moisture-proof, chemical corrosion resistance and wear resistance. environmental protection meets modern needs; High transparency is suitable for equipment with high appearance requirements; Easy to operate and suitable for a wide range of production methods. However, it also has disadvantages such as difficulty in curing where it is not illuminated, high cost, limited curing depth (special cases), and possible whitening of the coating film under certain conditions.

Advantages of UV conformal paint:

<!--[if!支持列表]-->1.<!--[endif]-->Fast Curing One of the biggest advantages of UV conformal coatings is their ability to cure quickly under UV light, typically in just a few seconds to tens of seconds. Compared with traditional conformal paints, which take a longer time to dry and cure, this greatly improves production efficiency and can meet the needs of rapid production in modern electronics manufacturing. The line does not spend a lot of time waiting for the coating to dry, and it can operate continuously, which is especially evident in large-scale production.

<!--[if!支持列表]-->2.<!--[endif]-->High adhesion UV conformal paint has high adhesion to all kinds of circuit board substrates, plastics, glass, metals and other materials. This indicates that it can adhere firmly to surfaces of different materials, providing reliable protection for electronic devices. Whether inside complex electronic devices or on components made of various materials, UV conformal paint can play a good protective role and is not easy to peel off or peel off.

<!--[if!支持列表]-->3.<!--[endif]-->Good protection Waterproof and moisture-proof: UV conformal paint has excellent waterproof performance, which can effectively prevent moisture from penetrating into electronic devices, avoiding short circuits, corrosion and other problems caused by moisture. For electronic devices used in humid environments (e.g. bathrooms, kitchens) or outdoor electronic devices, the waterproof properties of UV conformal coatings provide reliable protection for equipment. Chemical resistance: It can resist the attack of chemicals such as acids, alkalis, and solvents, and can protect electronic devices in harsh chemical environments. In the fields of chemical industry, battery production, etc., electronic devices are often exposed to various chemicals, and the chemical resistance of UV conformal coatings ensures the normal operation of equipment. Wear resistance: The cured UV conformal paint has high hardness and wear resistance, and can withstand a certain degree of friction and scratches, maintaining the surface finish and aesthetics of electronic devices. In daily use, electronic equipment will inevitably be subjected to some slight friction and collision, and the wear resistance of UV conformal paint can effectively protect the surface of the equipment from damage.

<!--[if!支持列表]-->4.<!--[endif]-->Good environmental protection UV conformal paint is a solvent-free or low-solvent coating, which will not emit volatile organic compounds (VOCs) during the construction process and cause less pollution to the environment. With the continuous improvement of environmental awareness, more and more enterprises and consumers have begun to pay attention to the environmental performance of products, and this characteristic of UV conformal paint makes it highly competitive in the market.

<!--[if!支持列表]-->5.<!--[endif]-->High transparency UV conformal paint has good transparency, and after coating, it will not affect the appearance and color of electronic devices, and can maintain the original appearance of the coated object. This is important for electronic devices such as smartphones and tablets that require a high degree of appearance. At the same time, high transparency also facilitates the observation and detection of circuits and components inside electronic devices.

<!--[if!支持列表]-->6.<!--[endif]-->Easy to operate UV conformal paint can be applied through spraying, brushing, dipping and other methods, making it easy and convenient to operate, suitable for different types and scales of production. Moreover, it can adopt the equipment spraying process, which can achieve precise control and improve the automation level of the production process.

Disadvantages of UV conformal paint:

<!--[if!支持列表]-->1.<!--[endif]-->Difficult to cure where the light does not reach Some shadowed areas and dead zones on the board may not reach UV light, which can lead to uneven curing of the coating as a whole. However, Nufil has independently developed a UV moisture double-curing conformal paint CA6001 that can be UV cured and moisture cured, which can solve the problem of UV curing well.

<!--[if!支持列表]-->2.<!--[endif]-->Higher Cost Compared with traditional conformal paints, the price of UV conformal paints is relatively high. This is mainly because the formulation of UV conformal paints uses more expensive raw materials, which increases the production cost. Moreover, the use of UV conformal paint requires suitable ultraviolet irradiation equipment, which is more expensive than other types of conformal paint.

Conclusion In fact, in addition to the above two disadvantages, UV conformal paint may also have the disadvantage of limited curing depth, and for some thicker coatings or electronic devices with complex structures, the inside of the coating may not be completely cured. However, the coating of the circuit board is usually not too thick, so this disadvantage is basically negligible. Of course, under certain conditions (such as unsuitable temperature and excessive moisture), the coating film of UV conformal paint may appear whitening like conventional conformal paint, and paying attention to the temperature and humidity of the sizing environment can also avoid such shortcomings.

When you have a comprehensive understanding of UV conformal paint, you can choose the appropriate conformal paint product and construction process according to the needs and conditions during application, which will help UV conformal paint play a better protective effect. However, the UV moisture double-curing conformal paint CA6001 developed by Nufil can solve some curing problems, and in most cases, such as when the circuit board coating is not thick, the disadvantages of limited curing depth can be ignored, and pay attention to the sizing environment to avoid the whitening problem of the coating film. In practical applications, a comprehensive understanding of its advantages and disadvantages can help choose the right product and construction process according to the needs and conditions, so that the UV conformal paint can achieve the best protection effect.
