Epoxy resin generally refers to the organic polymer compound with two or more epoxy groups in the molecule and forms a three-dimensional crosslinked network cured product under the action of appropriate chemical agents. Except for a few, its molecular weight is not high. Waterborne epoxy resin is a stable dispersion system prepared by dispersing epoxy resin in water in the form of particles, droplets or colloids. Waterborne epoxy resin has strong substitution ability for solvent based adhesives, and even better than traditional solvent based adhesives in some cases. Waterborne epoxy resin is mainly used in automotive parts, railway, agriculture, containers, trucks and other protective coatings. It has a wide range of applications and good prospects for industrial development.
Waterborne epoxy resin is mainly used in the coating field. Under the general trend of global environmental protection, the application demand of waterborne epoxy resin continues to rise. In 2020, the global epoxy resin market revenue reached US $1122 million, and it is expected to reach US $1887 million in 2027, with an annual compound growth rate of 7.36% (2021-2027).
In the past few years, China has actively promoted the reform of container coatings and transformed the container coatings market from solvent based coatings to water-based coatings to reduce the discharge of solvents. The application demand of water-based epoxy resin continues to grow. In 2020, the market scale of China's water-based epoxy resin is about 32.47 million yuan, and it is expected to reach about 50 million yuan by 2025, with an annual compound growth rate of 7.9% (2021-2027). With the growth of market demand, the output of waterborne epoxy resin in China has also increased from 95000 tons in 2016 to 120000 tons in 2020, with an average growth rate of 5.8%.
Waterborne epoxy resin is harmless to the environment because of its zero VOC emission. Therefore, these resins are widely used in the coating and adhesive industries. Market growth is largely affected by strict EU regulations. For example, according to European Conference Directive 2004 / 42 / EC, the emission of volatile organic compounds (VOCs) is restricted due to the use of organic solvents in decorative paints and varnishes and the use of automotive touch-up paints.
Globally, coatings are still the most important application of waterborne epoxy resins. In 2019, 56.64% of waterborne epoxy resins were used in the production of coatings, 18.27% in the production of composite materials, and 21.7% of the total adhesive consumption.
In terms of development, with the development of manufacturing and industrialization, the demand for waterborne epoxy resin in automobile, architecture, furniture, textile and other fields continues to rise, and the construction field is the fastest growing application field. However, with the development of intelligent and energy-saving automobile in the future, the automotive industry will continue to grow, so the application prospect of waterborne epoxy resin in the automotive field is good.
In terms of market competition, the competition among waterborne epoxy resin manufacturers in the global market is fierce. Waterborne epoxy resin has environmental protection advantages and a wide range of applications. In recent years, the market demand has continued to rise. In the future, driven by the development of terminal buildings, automobiles and other industries, the market demand for waterborne epoxy resin will continue to grow.
