The polishing performance of UV primer first saves a lot of time for the coating process and significantly improves the overall construction efficiency. After the traditional primer is cured, it often takes a long time to reach the polishable state, and the sandpaper is easily stuck and the polishing is not smooth during the polishing process, which not only prolongs the time of a single process, but also may affect the progress due to repeated polishing. UV primer has a fast curing speed, moderate surface hardness after curing, low resistance during polishing, slow wear of sandpaper, and can quickly remove minor flaws and unevenness on the surface. This smooth polishing experience reduces the polishing time of a single workpiece, allowing subsequent processes to be connected faster, especially in mass production, which can significantly shorten the overall coating cycle and increase the amount of workpieces processed per unit time.
Its polishing performance directly helps improve the flatness of the coating surface, laying a good foundation for subsequent coating. In the coating process, one of the main functions of the primer is to fill the fine pores and scratches on the surface of the substrate, and polishing makes these filled surfaces smoother. The film layer formed after UV Primer is cured has a uniform texture. When polishing, there will be no local overhardness or oversoftness. It can ensure that the surface is evenly trimmed to avoid local depressions or bulges caused by uneven polishing. This flat base makes it easier for the topcoat to adhere evenly, reduces the problems of sagging and pinholes in the topcoat due to the uneven base, and improves the overall quality of the final coating.
The polishing performance of UV Primer can also reduce the generation of dust during the polishing process and improve the construction environment. When polishing traditional primers, due to the loose material or insufficient hardness, a large amount of dust is easily generated, which not only pollutes the air, but also is inhaled by operators, affecting health. The film layer structure after UV Primer is cured is dense, and the debris particles are large and not easy to fly during polishing, which reduces the dust concentration in the air. This not only reduces the pollution to the construction environment, but also reduces the interference of dust on subsequent coating processes - such as defects caused by dust attached to the undried topcoat, but also reduces the protection burden of construction personnel, allowing the coating process to be carried out in a cleaner and healthier environment.
In terms of material utilization, excellent grinding performance reduces the waste of primer and reduces the cost of painting. If the grinding performance of the primer is not good, it may be necessary to apply multiple coats of primer repeatedly to achieve the ideal flatness, which undoubtedly increases the amount of primer used. However, uv primer only needs a thin layer to form a uniform film layer, and less excess material is removed during grinding, which can meet the needs of filling and trimming without causing excessive consumption. At the same time, smooth grinding also reduces the scrapping of workpieces due to improper grinding - for example, excessive grinding exposes the substrate and requires re-priming, which indirectly reduces the waste of materials and labor, making the coating process more economical and efficient.
Its grinding performance also simplifies construction operations and reduces dependence on operator skills. The grinding of traditional primers requires rich experience to grasp the strength and angle to avoid excessive or insufficient grinding, and novice operators are prone to mistakes. However, uv primer feels stable during grinding, and the grinding effect is less affected by human factors. Even operators with less skilled skills can quickly master the grinding skills and produce surface effects that meet the standards. This not only reduces the difficulty and cost of personnel training, but also reduces rework caused by improper operation, improves the stability of the coating process, and ensures the consistency of workpiece quality in mass production.
The grinding performance of uv primer has a positive impact on the continuity of the multi-coat coating process, reducing the waiting and adjustment time between processes. In complex coating processes, it is often necessary to apply and polish multiple primers and topcoats, and the connection efficiency between processes directly affects the overall progress. Since uv primer polishing is fast and the effect is stable, one process can be completed in a short time and transferred to the next one, without waiting for the polishing effect to meet the standard. At the same time, the surface state after polishing is stable, and no additional inspection and adjustment steps are required, so that the subsequent topcoat coating can be carried out directly, ensuring the smoothness of the entire coating process and avoiding overall delays caused by a certain process jam.
In addition, good polishing performance can also improve the adaptability of the coating process, allowing it to better cope with different types of substrates and workpieces. The surface properties of different substrates (such as wood, metal, and plastic) vary greatly, and the requirements for primer polishing are also different. The polishing performance of UV primer has a certain versatility. Whether it is facing a porous wood surface or a smooth metal surface, the ideal effect can be achieved through appropriate polishing methods. This adaptability reduces the trouble of adjusting the polishing parameters or changing the primer type due to the change of the substrate, allowing the coating process to handle a variety of workpieces more flexibly, enhancing the compatibility and adaptability of the production line, and is especially suitable for small batch and multi-variety production needs.
