In the chemical industry, zinc-rich primers are not resistant to acids and alkalis; therefore, zinc-rich paints cannot be used in environments with such substances. Zinc-rich paint is not resistant to alkalis; although it is alkaline itself, its use in alkaline environments is rarely seen in industry. It was once soaked; 60 microns of 5% sodium hydroxide caused it to fall off after 48 hours. In industrial applications in high-temperature environments, inorganic zinc-rich paints are often used; for example, an inorganic zinc-rich primer is applied to chimney dust removal pipes, followed by the use of silicone-aluminum powder paint.
