Beijing Nonferrous Metal Research Institute has recently developed a non-toxic weatherable epoxy heavy anti-corrosion coating that is suitable for marine engineering, chemical anti-corrosion, food industry, construction and decoration industry, and has broad application prospects. It has been used by Guangzhou Guanhua Metal Materials Co., Ltd., China Dongfang Electric Group, Tianjin Rizhi Brewery Co., Ltd., Guangdong Chenghai Construction Committee, Shenyang Railway New Construction Co., Ltd., and Changchun Railway Branch.
The coating uses epoxy resin as a basic film-forming substance. By adding a toughening agent, a coupling agent, a curing agent, an anti-foaming agent, and optimizing the pigment filler, the coating is formed on the surface of the steel structure and becomes excellently resistant. Epoxy thick paste type coating with weathering resistance, chemical resistance, no bubbles, no volatile solvent, no toxicity, no pollution, strong adhesion, and good construction performance.
"The development of non-toxic weatherable epoxy heavy anti-corrosion coating" is an important part of the National Natural Science Foundation of China's "non-ferrous metal atmospheric seawater corrosion data accumulation and regularity study". The paint absorbed the essence of the relevant results, not only has the excellent properties of epoxy coating itself acid and alkali corrosion resistance and good adhesion, but also passed the reasonable choice of curing agent and solid color, filler, so that it has a significant weather resistance Improves and eliminates holes in the coating film to the utmost, making it an excellent marine engineering coating. Due to the use of non-toxic raw materials and excellent organic solvent resistance, it has passed strict health and epidemic prevention tests and has been used in the food industry. It has been applied to the decoration of buildings, waterproof, moisture and seepage prevention due to good leveling performance.
As the methods and methods used are advanced and reasonable, the developed coatings are at the leading level in the field of epoxy coating development due to corrosion resistance, weather resistance, non-toxicity, good leveling, and low cost. There is no report on this multi-purpose coating at home and abroad.
