The Present Situation and Development Trend of Heavy Anti-corrosion Coatings in China

In 2009 after the financial crisis, under the continuous promotion of the national economic stimulus plan, China’s economy showed signs of slow recovery. However, the impact of the financial crisis on China's paint industry remains grim. In 2009, China's paint output created the world's largest production of 7.55 million tons, but it is not a world paint power. Analysis of the development of China's paint industry has gone through more than 60 years of history, heavy anti-corrosion coating, in promoting the development of China's paint industry, made great contributions.

Today, we follow the development path of heavy anti-corrosion coatings and analyze the market of China's heavy anti-corrosion coating industry:

Heavy anti-corrosion coating development

The concept of heavy anti-corrosion coating originated in Japan in the 1960s. It refers to a paint that has a long-lasting life and is used in the field of harsh corrosive environments. The so-called severe corrosive environment refers to a highly corrosive environment. According to the definition of ISO 12944-2, the atmospheric environment is C4 high, C5-I is highly industrial, C5-M is very high in the sea, and it is immersed in sea water or salty water. Im2's corrosive environment. The so-called long-term life is not exactly defined, generally considered to be more than 5 years of service life, that is, ISO 12944-5 provides medium or higher coating life. Heavy anti-corrosion coating has the following characteristics: high-thickness film, good surface treatment performance, application of new resin and pigment filler, etc., all determine the excellent performance of heavy-duty anti-corrosion coating itself, and establish immortal feat in the process of national construction.

The industrialization of European countries in the middle of the 17th century prompted the development of coatings to enter a new era. On the one hand, the development of social productivity and the improvement of living standards have constantly put new demands on the variety and quality of coatings. On the other hand, scientific and technological progress, especially the development of organic chemistry, and the emergence of new types of resins, are coatings. The large-scale production offers the possibility, but overall, these coatings have generally anti-corrosion properties and the coating has a short protection period. Until 1967, the emergence of thick-film epoxy coatings only showed true heavy-duty coatings.

In 2007, the world's new containers reached 3.5 million TEUs. In 2009, it was affected by the financial tsunami and fell to about 280,000 TEUs. It is expected that this year it will rise back to about 1 million TEUs. This downward trend has a great impact on the container coating business. According to HC Coatings Network, Liang Yanfeng, executive director of COSCO International, expects that the demand for container coatings will continue to grow in the third quarter of this year. However, with the arrival of the off-season container shipping market, the container manufacturing market in the fourth quarter is uncertain. He also said that the profit margin of its container coatings will increase in the second half of the year. In the first half of this year, the sales volume of container coatings of COSCO International’s Kansai Co., Ltd. reached 24,300 tons, a year-on-year increase of 13.44 times.

Marine paint

According to statistics, since the year of 2002, the marine coatings market in Asia has grown steadily, and the average annual growth rate of the market is between 6% and 8%. Asia currently occupies almost 60% of the global marine coatings market. The corresponding terminals are also highly concentrated in Asia. Ship maintenance also requires a large amount of paint. In 2007, the scale of the Asian marine paint market was approximately US$2.69 billion. Therefore, many companies in Japan, Europe, and the United States will extend their tentacles to China and attempt to share a share. The competition in the domestic high-end ship coating market tends to be "white hot." By the end of 2008, the total volume of China's marine coatings and container coatings reached 450,000 to 500,000 tons, which has grown to become the second largest category of industrial coatings after furniture coatings.

From a global perspective, the amount of shipbuilding completed is greater than the amount of orders for new ships, and the order volume of ship-held ship companies is continuing to decline. As of the end of May, orders for hand-held vessels for shipbuilding nationwide totaled 186.4 million dwt, a decrease of 0.9% from the end of 2009. “The evacuation of existing orders and the reduction of handheld orders have caused an unstable outlook for the shipping market. The difficulties caused by the European sovereign debt crisis and overcapacity in the global shipbuilding industry have adversely affected China’s shipbuilding industry. At present, the industry is picking up a foregone conclusion. However, continued improvement is still to be observed.” The warming of the shipbuilding industry will surely drive the paint industry to pick up, but the pace of recovery will be slow.

Wind power coating

Wind power generation is a new energy industry that has developed rapidly in recent years. Compared to thermal power generation, wind power does not consume carbon energy and no carbon dioxide emissions. Compared with nuclear power, wind power core technology is less difficult and there is no potential risk of nuclear leakage; Geothermal power has less initial investment in construction. The site of the paint for wind power is mainly the tower and the blades. Due to the different substrates, the paint used is very different. In recent years, China has invested a great deal of effort in wind power generation. Wind power equipment can be seen in many places such as the northwest, northeast, and southeast coasts. For China's wind power coating companies, it is full of development opportunities. In 2009, Akzo Nobel achieved more than 80% growth in sales of wind power coatings in China.

Tank coating

Storage tanks are important infrastructure for petroleum, chemical, grain and oil, food, firefighting, transportation, metallurgy, and national defense industries and strategic reserves. They play a very important role in the development of the national economy. Our economic life is always inseparable. Open large and small storage tanks. From the points of manufacturing materials, there are mainly three kinds of storage tanks: cement, glass steel and steel tanks. Under normal circumstances, only the inner and outer walls of steel tanks need to be coated with anti-corrosion paint to achieve anti-corrosion. At present, paints for large-scale steel storage tanks are mainly concentrated in major energy and chemical giants such as PetroChina, Sinopec, CNOOC, and Sinochem Group, as well as in the state's strategic petroleum reserve pool under construction.

With the rapid development of our country’s economy, our country’s dependence on petroleum has become higher and higher, and the country has also established a national oil reserve base.

Since 2003, China has begun preparations for the establishment of an oil reserve base. The preliminary plan uses 15 years to complete the construction of oil facilities and other hardware facilities in three phases. Reserves are roughly: the first period is 10 million tons to 12 million tons, which is equivalent to about 30 days of China's net oil imports; the second and third periods are 28 million tons respectively. The real opening of the domestic oil strategic reserve should begin with the delivery and use of Zhenhai Base, the first national oil reserve base in October 2006. Zhenhai Base is located in Ningbo City, Zhejiang Province, with a construction scale of 5.2 million cubic meters and a total of 52 oil storage tanks. In addition to the township's overseas, the Zhoushan, Huangdao and Dalian projects included in the first phase of the national plan have a storage capacity of 5 million cubic meters, 3.2 million cubic meters and 3 million cubic meters respectively.

The second stage is from 2008 to 2010, which will increase the reserve capacity to 300 million barrels, equivalent to 40 days of China's net oil imports. The third phase will increase reserve capacity to 50,000 barrels. China is also preparing to build a large-scale underground oil storage facility with a reserve capacity of 44 million barrels of national oil reserve base.

With the increase of China's oil reserve bases and the increase in the number of oil storage tanks, the demand for petroleum storage tank coatings has also surged, and the quality requirements for coatings have also been continuously improved. With the advancement of storage tank construction, the amount of paint for future maintenance and maintenance will inevitably increase gradually. Many of the tank farms are located in environments with high ambient humidity and high corrosiveness such as seaside and mountainous areas. Recoating and construction are difficult and the surface treatment costs are high. The surface of the old oil tank is difficult to remove, and the ordinary oil tank can not be attached after the anticorrosion paint is applied. Therefore, there will be a broad market space for low surface treatment tank repair coatings with rust, moisture, and oil.

The State of Heavy Anti-corrosion Coatings and Its Development Trend

Bridge coating

Under normal circumstances, the coating of large steel bridges will need to be refurbished every 5 to 10 years. This will result in an increase in the cost of operating the bridge and sometimes even affect the normal passage of the bridge. In recent years, more and more bridge owners and design agencies in China have tended to adopt a fluorocarbon paint with a long-term anti-corrosion limit for a period of up to 20 years to prolong the renewal repainting period of bridge anti-corrosion coating. According to statistics, nearly half of China's steel bridges that were opened to traffic after 2005 have been treated with anti-corrosion paint. With the continuous increase in the number of cross-sea, cross-river, and river-crossing bridges in China, the demand for anti-corrosion coatings for bridges has increased year by year, and quality requirements have also gradually increased. The bridge paint is more representative of COSCO Kansai Coatings.

In 2009 after the financial crisis, under the continuous promotion of the national economic stimulus plan, China’s economy showed signs of slow recovery. However, the impact of the financial crisis on China's paint industry remains grim. In 2009, China's paint output created the world's largest production of 7.55 million tons, but it is not a world paint power.
