Chemical resistant paints and coatings are specifically formulated to protect against harsh chemicals and acids. Whether it is a concentrated form of acid like sulfuric or hydrochloric, or the normal day-to-day use of chemicals like solvents, cleaning products and even spills or fumes – the right chemical resistant coating will help prevent damage and corrosion to substrates.
Tnemec offers a wide variety of chemical-resistant paint and coating systems designed to meet the specific demands of different environments. From mat-reinforced secondary containment to vinyl ester tank linings, we provide coatings that can be applied to concrete or metal substrates in industrial environments. These include storage and cargo tanks, piping, bunds, and underground metal and concrete structures, treatment plants, and laboratory and manufacturing facilities.
There are a number of factors that affect the chemical resistance of a particular coating, including:
The type of chemical(s) – each chemical is different and requires a specific chemical-resistant coating to withstand it. The concentration of the chemical(s) – a higher concentration of a chemical will require more resistant coatings than a lower concentration. The temperature of the chemical(s) – heated chemicals add another element to consider.
Epoxy is often the coating of choice for applications where a chemical-resistant coating is required. Epoxy can be applied to concrete and metal surfaces, and provides excellent resistance against many corrosive chemicals, including sulfuric acid, hydrochloric acid, caustic soda, phenol and formaldehyde. It is also an ideal choice for lining applications in a range of environments, from cold storage rooms to freezers.
