If paint is used in the decoration of a new house, it always needs to be ventilated for a long time before moving in. Paint, which evaporates toxic and harmful substances, poses a great threat to human health and is also the third major cause of haze formation. Is there a type of paint that can effectively solve pollution problems and allow delicate goldfish to swim in it? Let's take a look at the production practice of Changmu (Ningbo) New Material Technology Co., Ltd. located in Ningbo High tech Zone (New Material Technology City).

According to statistics, there are nearly 800 paint companies in China with annual sales exceeding 100 million yuan. Most of them produce traditional solvent based coatings, while "Changmu" new materials specialize in producing water-based paints made from water-based resins. Although the current market share of water-based industrial paint is less than 5%, based on the country's environmental policies and the external driving force of 'oil to water' in the industrial paint field, this new type of paint is reaching an explosive point, "said Yu Guo, Chairman of Changmu New Materials Company.

It is reported that traditional solvent based coatings contain over 60% organic solvents, which can evaporate at room temperature and pressure and are not easy to recycle or transport, causing serious air pollution. Water based paint replaces organic solvents with water and can completely replace traditional paints, with a usage cost only half of solvent based coatings. If all traditional solvent based paints in the country are replaced by water-based paints, it can save more than 80 billion yuan in usage costs per year, "said Yu Guo.

The flagship product of "Changmu" new material is air drying self crosslinking water-based resin. It is reported that currently, the biggest pain point of water-based paint in China is the need to use it through physical swelling and volatilization to form a film. This means that water-based paint can only be physically dried, not only does it lack water resistance, but it also does not resist corrosion or rust, and is generally only used in the field of home decoration. The "Changmu" new material takes this as a breakthrough point, innovates the water-based resin process, and finds a new path to solve the drying problem of water-based paint using chemical methods.

It's not an exaggeration to say that ordinary water-based paints will fade after being applied with a hot towel for a while. However, our air drying self crosslinking water-based resin made from water and vegetable oil can naturally air dry at room temperature for half an hour, and its water resistance, corrosion resistance, and rust prevention meet the standards of traditional paints. "Yu Guo told reporters that the cost of this new water-based paint is only 50% of that of ordinary water-based paint, and the emission of toxic and harmful gases is only 3.5% of the national standard for environmentally friendly coatings. At present, the ofo Xiaohuang car body, Dongfeng Group's water tank, and engine all use our air dry self crosslinking solution Yu Guo proudly said.

Moreover, "Changmu" New Materials is also a company in China that can provide a complete set of self drying water-based industrial paint solutions. "We sell 'meat'. By cultivating and checking high-quality food materials, we can ensure the health, safety and taste of meat from the source. Whether it is used for fried meat or Braised pork belly depends on customers' needs and hobbies," said Yu Guo.

At present, the latest water-based resin production line of "Changmu" new material has been established, and it is expected to produce 20000 tons of air drying self crosslinking water-based resin annually. This year, the company plans to achieve a sales revenue of 30 million yuan, a four fold increase from last year, and will 'reach 100 million yuan' next year, "said Yu Guo.
