Chemische Werke Huls Aktiengesellschaft’s hard unsaturated polyester resin LTH is used in some poor adhesion ethylene/acrylic, alkyd/polyester, epoxy, polyurethane coatings, which can improve the resistance to metals, minerals and specific plastics. The initial and long-term adhesion can also improve the adhesion between layers.
Law ter International, Inc.’s K-1717 is a ketone-based synthetic resin that is soluble in ketones, acetates and alcohols. It can make ethyl/acrylic, alkyd/polyester, epoxy, fiber The adhesion of plain coatings is improved. The aldehyde and ketone resin of Shanghai Xinhua Resin Factory is also this kind of product.
Professor Zheng Jiayan from the Department of Chemistry of Huazhong University of Science and Technology summarized inorganic and organic corrosion inhibitors in the article “Review and Prospect of the Development of Corrosion Inhibitor Technology”, and further analyzed molybdate, tungstate, and borate. The development of corrosion inhibitors, such as antimonates and modified silicates, has been prospected.
At present, the United States, Japan, Russia, the United Kingdom, Germany and other countries are all carrying out research work on coating corrosion inhibitors. The corrosion resistance of coatings with corrosion inhibitors has been greatly improved. However, corrosion inhibitors are added to coatings. , Has an impact on the stability and uniformity of the coating. It is a very difficult and realistic problem to find a ptfe in wax paint corrosion inhibitor that is compatible, stable, pollution-free and can improve the corrosion resistance of the paint. The effect of a single corrosion inhibitor is not good, and it is the development trend of corrosion inhibitors to achieve synergy and synergistic effects through the compounding of corrosion inhibitors. Such as the compound of molybdate and zinc salt, the compound of molybdate and organic phosphonate, the compound of molybdate, zinc salt and gluconate, etc. To make full use of corrosion inhibitors in coatings, it is necessary to conduct more in-depth research on the diffusion mechanism of corrosion inhibitors in solid coatings in order to truly understand. However, China’s research on coating corrosion inhibitors started late, and there is still a lot of work to be done. The future of corrosion inhibitors for coatings is promising.
