We recommend Polyurethanes for leak prevention in heat exchangers.
About half of the heat exchangers we are currently painting are for the purpose of preventing refrigerant leakage. In an environment containing acids, sulfur, and ammonia, corrosion occurs in the copper pipes of the vent section, leading to pinholes and resulting in the leakage of refrigerants and Freon. Polyurea prevents the occurrence of corrosion, thereby preventing Freon leakage. Although measures against Freon leakage are becoming stricter, we recommend Polyurea for preventing leakage in heat exchangers, which are one of the components that are difficult to replace. Please note that copper pipes that have already begun to corrode may experience leakage during the painting process, so as a rule, we do not paint anything other than new parts. *For more details, please refer to the PDF materials or feel free to contact us.

Company information
BLYGOLD JAPAN Co., Ltd. is a company that specializes in preventing salt damage and other issues in air conditioning and refrigeration equipment. BLYGOLD was established in the Netherlands in 1976 as a manufacturer dedicated to preventing the deterioration of heat exchangers, developing its own rust prevention agents and application methods, and began operations in Japan in 2009. BLYGOLD JAPAN's "Polyual" is a technology that protects the aluminum fins of air conditioning and refrigeration units from corrosion caused by salt damage and other factors. We take pride in the fact that, through maintenance contracts, we can maintain the coating semi-permanently, significantly contributing to the performance maintenance and longevity of air conditioning systems in Japan.
