Performance of a sandblasting-free metal paint applied to the inner walls of ethylene glycol storage tanks over 12 years

Thread Content

We know that for ethylene glycol storage tanks, the anti-corrosion treatment of the inner wall is generally achieved through metal thermal spraying followed by a sealing layer, and this method requires very strict construction standards. First, the metal surface treatment reaches Sa3 level ； Second, thermal spraying construction has relatively strict procedures. Additionally, this method has a long construction period ； The investment cost is high. The metal paint that uses a sandblasting-free coating system cleverly avoids the issues of strict construction requirements, long construction periods, and high costs associated with the aforementioned methods. A metal paint that requires no sandblasting after just one coating can last for over 10 years, with an investment cost of only about 30% of that for thermal spraying. The image below shows the process of applying metal paint without sandblasting, as well as the condition of the paint film surface after 12 years of use.
