Two component paints are becoming increasingly popular with the improvement of industrial coating standards and are widely used in industries such as automotive parts, industrial machinery, electronics, and woodworking. Common two-component paints include polyurethane paint, acrylic polyurethane paint, and epoxy paint.
Advantages of two-component paint
Unlike conventional single component paints where solvents evaporate to form a film, two-component paints are cured through a chemical cross-linking reaction between the main agent and curing agent. Therefore, using two-component paints can effectively reduce the emission of organic solvents during the production process and meet environmental protection requirements. The solid content of two-component paint is relatively high, resulting in a thicker paint film with ideal hardness and plumpness, effectively reducing the number of repeated spraying times on the workpiece and improving spraying efficiency. In addition, two-component paint has the advantages of good adhesion, corrosion resistance, and high glossiness.
Mixing accuracy of two-component paint
The main disadvantages of two-component paint compared to single component paint are its relatively complex usage and stricter working environment requirements. The use of two-component paint must strictly follow the mixing ratio specified by the manufacturer, mix the main agent and curing agent, and complete the spraying within the specified construction time. It can be said that precise proportioning is the prerequisite for maximizing the performance of paint, and timely spraying is the guarantee for achieving perfect coating effects.
Many people say that paint is "three parts quality, seven parts construction". The construction of paint and coatings must undergo strict process control, and the entire process of surface pretreatment, paint pre coating, coating quality control, coating environment control, and paint curing must be managed in a standardized manner. It can be said that experienced painters can significantly reduce paint waste and strictly control production costs for enterprises while ensuring coating quality. In today's fiercely competitive market, they are one of the key factors to successfully win the market. However, there is a saying that goes,‘One cannot make bricks without straw’. No matter how experienced and skilled a painter is, without the right spraying tools, it is difficult to complete the work with high quality.
As mentioned earlier, mixing accuracy is the primary condition for the performance of two-component paints. The traditional mixing method in many factories is manual mixing, and workers usually use mechanical mixers to mix paint. The ratio of main agent and curing agent is controlled by manual weighing, with an error of about 10%. Due to significant errors, sometimes problems arise during the early stages of curing, causing the paint to dry slowly and affecting the subsequent spraying of the topcoat; Some may not have problems in the short term, but after a period of time, they may experience discoloration, paint peeling, blistering, uneven brightness, and other issues. In addition, due to the cumbersome process of manual mixing, workers often mix excessively in one go, causing waste, as they are worried about not mixing enough and need to rework.
Electronic automatic mixing and dispensing system
The new mixing method for two-component paint is electronic automatic mixing and dispensing system.The mixing and dispensing system of the main agent and curing agent is centrally controlled by electronic mixing equipment, and the accuracy of the ratio can reach within 2%. Unlike manual mixing that involves excessive mixing in advance, the mixing action of electronic automatic mixing equipment is carried out simultaneously with spraying. The amount of paint sprayed by the spray gun is equal to the actual amount mixed, truly achieving on-demand mixing and almost zero waste of paint. At the same time, the mixed and sprayed working mode also avoids the problem of uncontrollable construction time after mixing two-component paint. In addition, electronic mixing equipment generally has automatic cleaning function, which is not only easy to operate, but also much faster than manual cleaning. In the furniture industry that requires frequent color changing and spraying, the advantages are particularly obvious.

Conclusion:
In today's world where environmental protection has become the main theme of development in various industries, two-component paints are widely popular for their excellent performance, low solvent emissions, and minimal environmental impact. Of course, two-component paints are relatively complex to use, so it is recommended to use professional two-component mixing and proportioning equipment. This can not only achieve precise proportioning and ensure stable spraying quality, but also greatly reduce paint waste, labor costs, and improve production efficiency in large-scale production. Therefore, in the long run, the return on investment is higher.
