Reporter survey: Water-based industrial coatings to replace oil-based industrial coatings is a foregone conclusion

The industry believes that the implementation of these standards will be an important milestone in the development of my country's water-based industrial coatings.

The market needsstandards to follow the trend

The new standard of "Waterborne Epoxy Anticorrosive Coatings" is applicable to waterborne epoxy resin anticorrosive coatings for metal substrates, and it puts forward relevant technical index requirements for primers, intermediate paints, and topcoats.

The new standard of "Waterborne Acrylic Resin Coatings" is applicable to water-based one-component or two-component coatings with acrylic resin as the main film-forming material.

"The implementation of these three water-based industrial coating product standards is undoubtedly the best interpretation of the current new national environmental protection regulations.

"This also shows that the development goal of water-based industrial coatings has been very clear, and it is also the general trend.

　　There are nearly a hundred types of industrial coatings.

　　"For the anti-corrosion of metal equipment surface, these three kinds of industrial coatings have the best anti-corrosion effect, and the amount is the largest, but they suffer from the lack of a unified standard, and the production of enterprises is very random.
Taking epoxy zinc-rich primer as an example, many small coatings Companies will sell industrial coatings with a zinc content of 20% as 40% zinc, so the anti-corrosion effect must be greatly reduced.
" Dai Maozhen, chairman of Shandong Liandi Paint Co.
, Ltd.
believes, especially if the coating product is in use When problems arise, the company and the user unit hold their own words, making it difficult for the appraisal department to judge which party is responsible based on a unified standard.

　　Yan Yongjiang, secretary-general of Shandong Paint Industry Association, said that with the increasingly stringent environmental regulations, the transformation of traditional solvent-based industrial coatings to water-based, powder and other environmentally friendly products has accelerated.
Among many water-based industrial coatings, water-based polyurethane coatings, water-based epoxy resin coatings and water-based acrylic resin coatings have received the most attention.
However, there are currently no unified standards for these products, and their product quality, environmental protection requirements and construction effects are all uneven.
Qi, there is an urgent need for relevant industry standards to regulate the market.

　　Standards are introduced and 　　companies have "launched" 

　　The latest statistics from the National Bureau of Statistics show that in 2014, the cumulative output of national coatings (based on 1344 companies above designated size) was 16.
481 million tons, an increase of 7.
9% year-on-year.
The top three output were Guangdong, Shanghai and Jiangsu, which reached 3.
3399 million respectively.
Tons, 1.
8709 million tons and 1.
8215 million tons, an increase of 6.
9%, 10.
5% and 5.
4% respectively year-on-year.

　　Huang Yue, Manager of Shandong Region of Suzhou Jiren High-tech Materials Co.
, Ltd.
believes that as a supporting industry of the national economy, the coating industry is widely used in real estate, steel, furniture, ships, automobiles, Home appliances and other industries, especially the current hot petroleum machinery, coal chemical equipment, and marine equipment industries, further provide a huge market for anti-corrosion coatings.
The large market potential, attractive product prospects, and the most environmentally friendly have become the biggest incentives for many coating companies to favor water-based industrial coatings and to enter the R&D and production of water-based industrial coatings.

　　"Because of such a large profit and a broad market, many companies that produce civil alkyd paint have also entered into anti-corrosion coatings, but they all produced oil-based anti-corrosion coatings at the beginning.
There are no less than 300 coating manufacturers in Changzhou.
" Shandong A technical engineer surnamed Li from Bestune Paint Industry Co.
, Ltd.
told reporters.

　　Yan Yongjiang also believes that the promulgation of these three water-based industrial coating standards will undoubtedly provide a benchmark for the production and R&D of coatings companies.
After the large-scale entry of water-based industrial coatings companies, the market is about to enter an explosive period.

　　The reporter learned that Shandong Benteng Paint Co.
, Ltd.
has begun to develop and produce water-based industrial coatings in 2012, especially the 500,000-ton water-based industrial coatings base built in Shandong Lunan Chemical Park, which can be called a masterpiece in the paint industry in Shandong.

　　The most noteworthy thing in the coatings industry is that after Shunde, Guangdong, Changzhou, Jiangsu has become the second city to be awarded the title of "Hometown of Chinese Coatings" by the China Coatings Industry Association.
As early as 2003, Changzhou was approved by the Ministry of Science and Technology to establish a national new-type coating industrialization base.
This is also my country's first national characteristic industrial base named after the coatings industry.
At present, the base is led by the CNOOC Changzhou Coatings and Chemical Research Institute.
Its development of water-based industrial coatings can be described as strong.
The output of new coatings accounts for nearly 1/10 of the country.
There are more than 250 various coating companies, including Lanling, Guanghui, Chenguang, etc.
10 A number of enterprises with annual sales exceeding 100 million yuan have obvious advantages in the water-based industrial coatings industry cluster.

　　Suzhou Jiren High-tech Materials Co.
, Ltd.
, which was listed on the NEEQ not long ago, took advantage of the listing opportunity to open up 6 large-scale production bases in Beijing, Shanghai, Suzhou, Huai’an, Hubei Yicheng, and Hebei Tangshan.
Its production base in Tangshan is positioned For the production of water-based industrial paint.

　　Subsequently, Lions Technology, Shark, Jizhong Chemical, Bentsel, Jinming Waterproof, Jiexi, Runli Chemical, Huicai Coating, Sanyin Coating, Obersen Coatings, and Fomeiao Coatings all expressed their With the help of listing financing, enter the production and development of water-based industrial coatings.
Among them, Sanyin Paint, Obersen Paint, and Fumeiao Paint have been successfully listed in the Shanghai Equity Exchange Trust Center this year.

　　Enterprise "launching" 　　technology has to be upgraded 

　　However, if some people are optimistic, others are not optimistic.

　　"The market share of water-based industrial coatings is still inferior to that of oil-based industrial coatings.
Many chemical companies still use oil-based industrial anti-corrosion coatings in large quantities in anti-corrosion projects.
" said Han Ming, chairman of Shandong Luniu Paint Industry Co.
, Ltd.
, in anti-corrosion coatings for steel structures.
, Epoxy coatings account for a considerable proportion.
Traditional solvent-based epoxy coatings produce a large amount of organic volatiles during the production and construction process.
Therefore, the development of water-based industrial anti-corrosion coatings such as epoxy resin coatings is naturally put on the agenda.

　　Under the increasingly stringent environmental regulations, why are oil-based anticorrosive coatings still the main product of coating manufacturers, and they are also the anticorrosive products that coating users have always been optimistic about? 

　　"The main reason is quality.
" Han Ming told reporters that oil-based industrial coatings are characterized by fast drying and good weather resistance, while water-based industrial coatings are much inferior.
A few years ago, some coating companies in Shandong introduced water-based industrial coatings, but a series of ills such as slow drying and peeling appeared during use, which caused many customers to shake their heads when they mentioned water-based industrial coatings.

　　Manager Yu of Changzhou Shuanghua Paint Co.
, Ltd.
also holds the same view.
He told a reporter from China Chemical Industry News: "The production technology of oil-based industrial coatings has become mature, while the market technology of water-based polyurethane coatings, water-based epoxy resin coatings and water-based acrylic resin coatings are in an immature state.
"

　　Manager Yu also emphasized that the price of water-based industrial coatings is also high.
The price of industrial anticorrosive coatings produced with domestic water-based resins is 20% higher than that of similar oil-based paints, while imported water-based resins will be 30% higher.
As the current industries that use industrial anticorrosive coatings such as coking, energy, oil refining, and fertilizers, under the background of overcapacity and new environmental protection policies, the benefits are not good.
They are not cold on high-priced water-based industrial coatings and directly choose low-priced oil-based anticorrosive coatings.
.
Global Coatings Network learned that low-priced water-based industrial anti-corrosion coatings using domestic water-based resins have unstable performance, which also affects the use of anti-corrosion coatings.

　　Yang Yuande, secretary general of the China Coatings Industry Association, analyzed that the development of water-based industrial coatings by coating companies is undoubtedly the greatest benefit to the environment, and it can also lower the price of foreign water-based industrial coatings brands in the current market and benefit domestic consumers.
However, water-based industrial coatings are environmentally-friendly high-end products with high technical content, and the production and painting processes are also very different.
Coating companies should make progress in this respect and cannot rush for success, otherwise immature water-based coating products will flow to the market.
The development and operation of the entire water-based industrial coatings industry will be affected.

　　Many companies also have absolute confidence in the prospects of water-based coatings.
"Although there are still problems of this kind of water-based industrial coatings at present, resulting in a small market share, if one day the relevant state departments forcibly prohibit the use of oil-based industrial coatings, oil-based coating companies will only have to go bankrupt.
" Shandong Yili Paint Industry Co.
, Ltd.
Said Wang Yongbo, sales manager of the company.
