Problems solved by technology

For anti-corrosion coatings, traditional protective coatings are limited by their own material properties and processes, and the corrosion protection effect on metal substrates is often not ideal. The cost of individual outstanding performance is high, which reduces the cost performance of coatings. Because the layer contains heavy metals or toxic substances such as lead, zinc or chromate, there is a certain risk of environmental pollution, and it also consumes a large amount of non-renewable resources, which is not conducive to the sustainable development of social economy
At present, due to the lack of domestic technology, there are relatively few heavy-duty anti-corrosion coatings or solvent-free anti-corrosion coatings, or the performance is not ideal; while the coating life or heavy-duty anti-corrosion, there are few coating formulations that take into account aging resistance and salt spray resistance.
[0003] At present, due to the relatively short application of graphene in China, there are fewer formulations and processes in the field of coating applications.
At the same time, it is more expensive and can only be used in high-grade coatings
