2018 foreign enterprises occupy 60% of the domestic
anti-corrosion coatings market share
heavy anti-corrosion coatings field is China's paint industry open to the outside world the earliest, the highest degree of internationalization of the field. Currently, internationally renowned heavy anti-corrosion paint brands Haihong Old Man (Hempel/Denmark), International Paint (International/Netherlands), Jotun /Norway, Zhong Tu (CMP/Japan), Master Paint (PPG/USA), Akzo Nobel (AkzoNobel/Netherlands), King Kong (KCC/Korea) and so on by virtue of its technology, brand, management advantages, in the domestic siege, has completed the domestic production and strategic layout in China, Libang, Xuanwei, PPG and so on in China have set up their own factories and laboratories, forming a high-end market for China's heavy anti-corrosion paint foreign enterprises monopoly situation. Domestic heavy anti-corrosion coating enterprises to small enterprises, in terms of capital, technology, brand and other aspects are difficult to compete with the international paint giants, this phenomenon in the anti-corrosion coatings, an important part of automotive anti-corrosion coatings, ship container coatings in the performance is particularly obvious. In the field of container and marine coatings, due to the high technical requirements for coatings, foreign-funded enterprises and joint ventures occupy 80% of the domestic market share, in general, China's defense rotting coatings market share of about 60% by foreign enterprises occupied, and foreign anti-corrosion coatings enterprises concentrated in the paint high-end market In the low-end market survival of domestic anti-corrosion coating enterprises and homogenization of serious problems, so that at present, many anti-corrosion paint enterprises in China's profit margins have been compressed to 10% of the normal profit warning line below, china's anti-corrosion coatings enterprises have a long way to go.

The existing problems in China's industrial anti-corrosion coatings industry
Since the reform and opening up, China's anti-corrosion coatings in the field of technology has made great progress. Some high-performance coating products have been developed and successfully applied to large-scale projects in many countries. However, compared with some well-known brands abroad, our overall level and foreign countries still have a large gap, the specific performance in the following aspects: First, manufacturers, relatively small scale, wide distribution, low profit level, can not compete with foreign well-known brands. China's paint manufacturers have more than 9,000, its annual sales of more than 200,000 t of large-scale paint enterprises are few, 80% of enterprises for small and medium-sized enterprises. Is a large enterprise, in the world paint enterprise size is not in the top 50. Second, the paint manufacturer's independent innovation ability is relatively insufficient, lack of core competitiveness. Third, the degree of specialization of paint manufacturers is not enough, incomplete support. Fourth, paint manufacturers tend to pay more attention to the product performance research, and the paint supporting system and construction process research is insufficient. Fifth, the level of standardization is low. Sixth, brand strength is not enough. In general, in the field of heavy anti-corrosion coatings, domestic enterprises lack core competitiveness, in the production scale, product grade, construction quality, service level, etc. are still a big gap, with the current strength is still difficult to enter the high-end market.

The development trend of heavy anti-corrosion coatings

hydration
With the public's more and more urgent and strict requirements for environmental protection, the development of low energy consumption, low pollution, high-performance water-based heavy anti-corrosion coatings has become one of the hot topics of current research. The key to the research and development of water-based heavy anti-corrosion coatings lies in the development of water-soluble film resins, and water-based epoxy, water-based fluorocarbons and water-based polyurethane and other anti-corrosion coatings have been successfully developed. However, water-based heavy anti-corrosion coatings still have the deficiencies of easy flash erosion, coating water resistance and relatively poor mechanical properties, and need to be further improved.

Anti-rust pigment non-toxic
as an important part of heavy anti-corrosion coatings, anti-rust pigments play a role in slowing metal corrosion, the common anti-rust pigment containing heavy metals, although excellent performance, but will cause great pollution to the environment, and therefore gradually limited in the actual use. In recent years, the use of environmentally friendly anti-rust pigments to replace traditional anti-rust pigments has become the current development direction of environmentally friendly heavy anti-corrosion coatings, but to completely replace the traditional toxic anti-rust pigments, the theory and application of non-toxic anti-rust pigments need to increase research and development efforts.

multi-functional
single function of heavy anti-corrosion coatings has been far from meeting the huge needs of the modern coating industry, heavy anti-corrosion coatings function diversification has become imperative. Such as composite ceramic anti-corrosion coatings, conductive polyphenylamine heavy anti-corrosion coatings, self-healing heavy anti-corrosion coatings, nano-composite powder zinc seepage aggravated anti-corrosion coatings. In order to promote the development and product upgrading of heavy anti-corrosion coatings and seize the commanding heights of the development of heavy anti-corrosion coatings in the world, we must pay high attention to the multi-functionalization of heavy anti-corrosion coatings.

coating integrated paint
three-point paint, seven-point construction. Paint itself can be said to be a semi-finished product, combined with coating will eventually become a finished product, it can be seen the importance of coating quality, coating quality directly determines the final engineering quality. So far, the integrated system management of coating coating is still the most urgent task in China's coating industry. In the development of coating products must take into account the research of coating process, only after the realization of coating integration, the final product can achieve "reliability", at the same time, the new coating process, coating technology will also promote the upgrading of coating products. In recent years, the surface treatment cost and labor cost of substrate before coating have gradually increased, which has promoted the development of low-treatment surface primer products, and the wet sand blasting and high-pressure water rust removal process has led to the development of wet rust surface primer. Of course, the new coating process also put forward higher requirements for the construction performance of coating products, which also promotes the performance of heavy anti-corrosion coatings. Comprehensive above analysis, is to strengthen the industry's coating norms, improve technical service capabilities, the establishment of high-quality technical service team.

the development direction of heavy anti-corrosion coatings
the development direction of anti-corrosion coatings is energy-saving and environmental protection, high performance and functional. This also requires the coating industry to develop towards water-based, solvent-free or high solidification, powdering, high performance and versatility, low surface treatment, heavy metalization and other low pollution, pollution-free direction. A variety of water-based coatings, high solids/solvent-free coatings, low surface treatment primers, nano-modified coatings, conductive polyphenyls, single-component moisture-cured polyurethane coatings, ultra-high-pressure water jet cleaning technology, as well as peelable protective coatings and new anti-fouling coatings for the marine environment and other new coatings are constantly concerned and developed. The development of environmentally friendly industrial heavy anti-corrosion coatings is a high-tech project that many developed countries are actively exploring, and is a new field in China. Due to the early integration with foreign technology and the drive of various regulations and policies, some environmentally friendly and efficient products have been widely used.
