Connecting function: As an intermediate coating, it can firmly adhere to the epoxy primer, and at the same time provide a good adhesion foundation for the subsequent topcoat, so that the entire coating system forms a tightly integrated whole, ensuring the adhesion and interlayer bonding between the coatings, and effectively preventing the coating from delamination and falling off.
Enhanced protection function: With its excellent shielding performance, it can effectively block the erosion of the substrate by external water, oxygen, salt spray, chemical media, etc., further enhance the anti-corrosion performance of the coating system, and extend the service life of the protected object. For example, on some steel structure buildings or equipment in harsh corrosive environments, the use of two-component epoxy micaceous iron intermediate coating can significantly improve the anti-corrosion effect.
Improve appearance function: It can fill the tiny flaws and unevenness on the surface of the substrate, improve the flatness and smoothness of the coating, and make the final coating surface more uniform and beautiful. This helps to improve the overall decorative effect for some objects with high requirements for appearance quality, such as automobiles, ships, mechanical equipment, etc. Function of increasing coating thickness: Without affecting the performance of the coating, the overall thickness of the coating can be increased, thereby improving the mechanical properties of the coating such as wear resistance, impact resistance and scratch resistance, so that the coating can better withstand external mechanical effects such as friction and collision, and protect the substrate from damage.
Function of extending the maintenance cycle: Due to its good weather resistance and chemical resistance, it can maintain stable performance during long-term use, reduce coating aging and damage caused by environmental factors and chemicals, thereby extending the maintenance cycle of the coating system and reducing maintenance costs.
