How long will a Blygold treated heat exchanger last?
Independent laboratories have tested Blygold coatings under accelerated conditions. Blygold coatings withstand the ASTM B117, Salt Spray Test and the ASTM G85, Acid Salt Spray Test in excess of 3000 hours. Practical cases have shown Blygold treatments to last for 10 years. Individual exposure conditions vary greatly. Contact your nearest Blygold applicator if you have any particular concerns or questions regarding any extraordinary or unusual exposure conditions.
