Advantages of Industrial Machinery Paint

Engineering machinery is an important component of the equipment industry, such as the necessary mechanical equipment for earthwork construction, road construction and maintenance, mobile crane loading and unloading operations, and comprehensive mechanized construction projects required for various construction projects. Construction machinery can be frequently seen in major fields related to national livelihood, such as national defense construction projects, transportation construction, energy industry construction and production, mining and other raw material industry construction and production, agriculture, forestry and water conservancy construction, industrial and civil construction, urban construction, environmental protection, etc.

With the continuous strengthening of environmental protection awareness and the increasingly perfect environmental protection regulations, as an environmentally friendly water-based coating, it has the significant characteristics of low VOC content and minimal harm to the environment and human body. This has provided a good foundation for the rapid development of water-based coatings in China, and has gradually entered some high-end industries in China.    

In recent years, China's construction machinery products have also experienced rapid development. Due to the large size of most construction machinery products, there is a high demand for coatings. The average amount of coatings used for an excavator reaches 50KG, and the market prospects for coatings used in construction machinery are very broad. In order to improve product competitiveness, construction machinery manufacturers are no longer limited to the internal quality and performance of their products, and are obtaining coatings with good anti-corrosion performance and appearance quality. At the same time, construction machinery coating is developing in the trend of energy-saving, environmentally friendly, and low-carbon coating technology applications. Due to the complexity of structural components in construction machinery, water-based coatings have become the preferred choice.    

Of course, it should be noted that water-based coatings also have very strict characteristics, such as strict requirements for surface pre-treatment of workpieces; The drying process requires strict control of humidity; Factors such as the need to use stainless steel equipment. Moreover, water-based industrial coatings also have certain requirements for the performance of primers and topcoats:

Primer: Industrial machinery paint, classified by resin, mainly includes alkyd primer, epoxy primer, polyurethane primer, acrylic primer, etc. Among them, two-component epoxy primer has the best comprehensive performance and is currently the most widely used coating.     

Topcoat: Polyurethane resin topcoat is a commonly used topcoat in the construction machinery industry in recent years, with high film hardness, gloss, fullness, wear resistance, and excellent comprehensive performance. The water-based two-component polyurethane topcoat has outstanding aging resistance and corrosion resistance.

At the same time, further consideration should be given to energy conservation and environmental protection requirements in industrial production, which have very high demands on the coatings used for painting. Engineering machinery coatings must have low permeability to moisture, air, and corrosive substances. For the coated materials, they should have strong adsorption force, long-lasting wear resistance, good rust prevention performance for metals, and good appearance display effect. They should have conductivity, insulation, and thermal insulation properties, and a complete set of coating schemes and processes for different situations. If considering energy conservation and environmental protection in industrial production, coatings with the above performance are still not enough. Excellent engineering machinery coatings should have the ability to quickly dry at low and normal temperatures, while also meeting the coating requirements for various equipment and components produced in large and small batches. And achieve advantages such as good coating effect, no defects, low pollution, weak toxicity, environmental protection and energy saving

At present, coatings used in mechanical and engineering painting applications can be roughly divided into two categories. One type is characterized by obvious rust prevention effect, while the other type has better appearance display effect. That is to say, choose the type of coating based on the main effect it reflects. It is worth pointing out that whether it is a coating with good rust prevention effect or a coating with beautiful appearance display effect, energy conservation and environmental protection are the characteristics that both should have. This is also an important trend in the research and development, production and use of mechanical engineering coatings.
