When it comes to coil coating, if not the industry, it may be a relatively unfamiliar word. Coil coating in the coating industry, although not as familiar as architectural coating, furniture coating, but is also an essential social development of an industrial coating.

Coil coating is composed of base material, crosslinking agent, pigments and fillers, additives and volatilization. According to its use, it can be divided into primer, back paint and top paint. It is used for coating the surface of steel plate and aluminum plate and is used after making pre-coated coil. Compared with other coatings, coil coatings in addition to the general coatings have corrosion resistance, decorative properties, but also has excellent elasticity and other special properties, widely used in construction, automobile manufacturing, home appliance manufacturing and other industrial fields.

Coil materials were first put into the market in the United States in the 1930s, and the development history of coil coatings in China began in the 1980s. With the development of China's economy, China's color steel plate industry production has been a rapid development, the national color steel plate production line from the beginning of a dozen to several hundred, thus China's coil coating market greatly increased. According to qianzhan network data statistics, in 2014, China's total production of coil coatings 458,852 tons, accounting for 2.78% of the total production of coatings. From 2007 to 2014, the compound growth rate of coil coating industry was 16.92%, showing a rapid growth momentum.

  According to the data of National Bureau of Statistics, as of December 2012, there are 240 enterprises above scale in China coil coating industry, among which 185 are private enterprises, accounting for 77.08% in the industry; There are 52 enterprises with foreign investment and investment from Hong Kong, Macao and Taiwan, accounting for 21.67% of the total number of enterprises in the industry, and only 3 state-owned enterprises, accounting for only 1.25% of the total number of enterprises in the industry. These enterprises are mainly located in eastern China. But from the perspective of sales revenue, although private enterprises occupy a dominant position in the coil coating industry, the proportion of 2012 was 66.79%, but lower than its proportion of quantity; The proportion of the number of foreign-funded enterprises is 21.67%, and the proportion of the sales revenue is as high as 31.37%, which is 10 percentage points higher than the proportion of the number. Thus it can be seen that although the number of foreign-invested enterprises is not large, they occupy a high market share. 

At present, color coated steel plate has a good application prospect, home appliance color plate has become the development direction of the industry, its application will be more and more common, and then drive the development of coil coating industry. In this case, those paint manufacturers and what actions?

On 11 February 2016, Akzonobel expressed its interest in acquiring basF's Industrial Coatings business, and on 15 December 2016, both parties also announced that Akzonobel had completed the acquisition of BASF's global Industrial coatings business. The acquisition will strengthen Akzonobel's leadership position as the world's largest supplier of coil coatings. Also in February 2016, Valspar announced that it had completed its acquisition of ISVA Vernici, a European coil coatings manufacturer. The move will boost Valspar's performance in the global coil coatings industry. In mid-2016, Astor Coatings Systems announced that it would complete the acquisition of a major interest in coil coatings manufacturer Dura Coat Products in the third quarter of this year. Through this cooperation, Axalta paint systems will better provide customers with more solutions.

In order to strengthen the coil coating business, these companies are pulling out all the effort, hoping to bring happy results.

With the tightening of national environmental protection policy, the market calls for low VOC coating products. Coil coating, as a low VOC product, has excellent anti-corrosion, weather resistance, durability and other characteristics, the application in home appliances, home decoration, construction and other fields will gradually increase. At the same time, the acceleration of the pace of "oil to water" will also make users in the Asia-Pacific region of waterborne polyester coil coating favor increasing. Moreover, in Our country, the application of coil coating in the automobile manufacturing industry is very prominent, China is the world's first automobile production country, automobile production is rising steadily. Compared with radiation curing coatings, coil coatings are more easily applied.

According to the latest market research report released by research firm Technavio, the global coil coatings market is expected to grow at a compound annual growth rate of more than 6% from 2016 to 2020. The research indicates that the construction industry is the largest application field of coil coatings (accounting for about 76.4%), and is the most important factor to stimulate the development of the global coil coatings market. This year, the Ministry of Housing and Urban-Rural Development plans to complete 6 million units of shantytown renovation housing, may be a new opportunity for coil coatings in the construction industry. According to the paint industry "13th Five-Year" plan to 2020, the total production of the paint industry is expected to grow to about 22 million tons, with an average annual growth rate of 5%. If according to the 2014 coil coatings accounted for 2.78% of the total coating production share to calculate, by 2020, coil coatings can reach more than 600,000 tons of production, plus a compound growth rate of 6%, conservative estimates to 2020 can reach more than 800,000 tons of production.

In conclusion, the coil coating market is broad and has a bright future. In the future, coil coatings will be developed in the environmentally friendly direction, including chromium-free pigments, lead-free pigments, high solid content coatings, waterborne coatings, powder coatings, low temperature curing coatings, light curing coatings, etc. In addition to increasing applications in construction, home appliances, automobile manufacturing and other fields, coil coatings will also develop more and more common in other application fields.
