Global Coatings Network News:
As human beings pay more and more attention to the environment and health, water-based coatings have been used more and more widely.
The pollution caused by the volatile organic compounds (VOC) released during the production and use of traditional solvent-based coatings has become the main source of pollution in cities after automobiles.
As one of the alternatives to traditional solvent-based coatings, water-based coatings can reduce VOC emissions, reduce the generation of hazardous waste, and reduce workers’ exposure to toxic emissions.
It is reported that during the "Thirteenth Five-Year Plan" period, the country will strengthen the control of the total amount of volatile organic compounds (VOC), and coordinate the reduction of nitrogen oxides and VOCs.
Industrial coatings for cars, ships, containers, furniture, and engineering All companies in the seven key occupations of machinery, steel structure and coil production must implement VOC management.
Environmentally-friendly low-VOC coatings will usher in a solid "warm spring", and the water-based industrial coatings are expected to catch up with architectural coatings, and they will go hand in hand.

Development status of water-based industrial coatings
Water-based industrial coatings are mainly used in automobiles, railway vehicles, bridge pipes, steel structures, containers and other fields.
At present, the level of water-based industrial coatings in China is far behind that of industrialized countries.
With the rapid development of the automotive industry, the amount of automotive coatings is also increasing.
In recent years, all new domestic automotive coating production lines are designed with water-based coatings, and water-based coatings have become the mainstream of automotive coatings.
As early as the 1960s, developed countries such as Europe and the United States have taken the lead in using water-based electrophoretic primers.
At present, more than 90% of the primers have adopted water-based coatings, and 88% of automobile intermediate coatings have also adopted water-based technology, with water-based metallic flashing background colors.
The application of lacquer exceeded 65%.
Railway vehicle coatings
Traditional solvent-based coatings are mostly used for car body coatings, which contain a large amount of organic solvents, which brings inconvenience and safety hazards to storage, transportation and construction.
At present, my country’s railway freight cars have successfully applied Huabao water-based industrial coatings to more than 13,000 vehicles.
The products have been verified for more than 5 years and can fully meet the quality standards of solvent-based products; the development of water-based coating systems for railway locomotives and passenger cars, Huabao The coating company has also completed and started testing after coating.
The localization and water-based process of coatings in the fields of motor cars, high-speed rail and rail transit have also entered the work plan of the General Railway Corporation.
Heavy anti-corrosion coating
The annual economic loss caused by metal corrosion in our country accounts for about 4% of the GDP.
Such an astonishing loss stimulates the development of anti-corrosion coatings.
The development of environmentally friendly industrial heavy-duty anti-corrosion coatings is a high-tech project being actively explored by coating experts in many developed countries around the world, and it is an emerging field in China.
There are water-based alkyd systems, water-based epoxy systems (epoxy mica intermediate coating and epoxy zinc-rich primer), water-based inorganic zinc-rich systems, water-based epoxy ester systems, etc.
, used in the field of heavy anti-corrosion.
Waterborne container coating
At present, the world's annual output of containers exceeds 3.
5 million TEUs, and the annual demand for coatings is about 400,000 tons, worth about 6 billion yuan.
At present, most of the container coatings used worldwide are solvent-based, causing serious environmental pollution.
In the face of increasingly stringent environmental protection laws, acrylic topcoats have begun to replace chlorinated rubber topcoats and special tank bottom paints.
Water-based container coatings have already begun pilot applications in China.
Support of water-based policies and regulations
Since the implementation of the 4% paint excise tax on February 1, 2015, the National Coatings and Pigment Standardization Technical Committee is responsible for the formulation of "Waterborne Polyurethane Coatings" HG/T4761-2014 and "Waterborne Epoxy Coatings" in just 4 months.
Three water-based industrial coating product standards including "Resin Anticorrosive Coatings" HG/T4759-2014 and "Waterborne Acrylic Resin Coatings" HG/T4758-2014 will be officially implemented on June 1.
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.
Major events in domestic water-based industrial coatings
With the drastic introduction of a series of environmental protection policies by the Chinese government to promote the rapid development of environmentally friendly coatings, many domestic companies have upgraded and transformed or increased investment in water-based coatings research and development.
The development and market share of water-based coatings has increased year by year.
An indisputable fact, and there is a tendency to speed up.
In March 2015, Haolisen Paint (Shanghai) Co.
64 million yuan to build a new water-based electrophoretic coating project with an annual output of 100,000 tons.
After completion, it will be the most advanced and automated water-based industrial coating manufacturing plant in Asia.
In October 2015, the Gansu Waterborne Industrial Coatings Engineering Research Center, led by Northwest Yongxin Coatings Co.
and Lanzhou University and Lanzhou University of Technology, was formally established with the approval of the Gansu Provincial Development and Reform Commission.
In March 2016, the Foshan Science and Technology Bureau announced the establishment of Foshan Engineering Technology Research Center.
Hualong Paint was approved to establish the "Foshan Healthy Waterborne Industrial Coating Engineering Technology Research Center" and was selected for the establishment of Foshan Engineering Technology Research Center in 2015 plan.
In May 2016, in view of Shuanghu's unremitting efforts and outstanding achievements in the development of water-based coatings, Shuanghu Coatings was awarded the title of "Hubei Coating Industry Water-based Industrial Coatings R&D Base" issued by the Hubei Coatings Industry Association.
Low-carbon environmental protection promotes the water-based process of industrial coatings
According to data from the National Bureau of Statistics, in 2015, the total output value of coatings of 2026 paint manufacturing companies across the country reached 418.
484 billion yuan, an increase of 7.
3% year-on-year, and the cumulative national coating output reached 17.
17557 million tons, an increase of 4.
However, environmentally friendly The paint usage rate is less than 40%, while developed countries in Europe and America have reached 70%-80%.
The data shows that the sales revenue of the water-based coatings market in the Asia-Pacific region will increase from US$11.
9 billion in 2012 to US$16.
7 billion in 2016, with an average annual growth rate of 8.
The development of the water-based coatings industry will enter a period of high growth, of which China will become the Asia-Pacific region.
The main force in the development of the regional water-based coatings market.
It is reported that European water-based industrial coatings have accounted for 40%.
In the field of special coatings, water-based coatings are developing at an unprecedented speed in areas that account for a large proportion of automotive coatings, anti-corrosion coatings, and road marking coatings.
Domestic water-based coatings still have a lot of room for development in the field of industrial coatings.
At present, in the field of heavy anti-corrosion, it is difficult to develop due to limited technical conditions.
In my country's automotive coatings, 90% of the primer is water-based, and the topcoat is water-based.
The rate has reached about 50%.
Although the water-based rate of automotive repair coatings is not high, it is subject to requests for environmental management of the automotive repair industry from multiple key areas represented by Beijing, and the company already has water-based automotive repair coatings.
Skill reserves, this field will also see rapid growth.
In addition, the development of water-based coatings for container coatings and construction machinery is even more promising.
