chemical resistant coating on a black table

Chemical resistant coatings provide extreme substrate protection

Nearly all coatings will be exposed to chemicals at some point, whether cleaning products, spills, or fumes. However most of these are mild, and the coating does not need a special formulation. Chemical resistant coatings or paints are designed to provide protection from the harshest of substances. They need to perform safely and consistently under punishing conditions, and so need to be highly resistant. Without proper chemical resistant coating, solvents, acids, alkalis, salts, and other substances can be absorbed by the substrate, causing deterioration and contamination.

The right chemical resistant coating is the one that satisfies the requirements of the chemical, as well as the needs of the substrate. Choosing correctly requires fully understanding both. In this article we will outline the different chemical resistant coatings options, and provide a guide for choosing the right one as well as where to find products and applicators in the Philippines.

The 1st step – what is expected from the chemical resistant coating

Substrates and environments which require heavy duty protection from chemicals include flooring, storage or holding tanks, pipelines, bunds, buried metal and concrete structures, treatment plants, laboratories, cooling towers, factories, machinery and equipment, just to name a few.

You might need a hydrochloric acid resistant coating, or sulfuric acid resistant coatings, chemical tank lining, or chemical resistant paint for steel. The range of substrates, environments, and chemicals is matched by the range of chemical resistant coatings. To choose the right chemical resistant coating you need to know:

  • The type of chemical/s – each coating has different strengths, and may provide protection from one chemical but not another.
  • The concentration of the chemical/s – the strength of the chemical will obviously affect the coating’s resistance.
  • The temperature of the chemical/s – a heated chemical adds an extra factor for the coating to deal with.
  • The degree of exposure to the chemical/s – will the substrate be immersed, or is it just contact exposure?
  • The duration of the exposure – how long will the coating need to withstand the chemical?

Types of chemical resistant paint to choose from

Chemical resistant coatings are available in a wide range of formulations, suited to different applications. The main types are polyurethane, epoxy, phenolic, and fluoropolymers. The choice of coating is further complicated by extra requirements such as high abrasion resistance, increased corrosion protection, or sufficient lack of friction.

Phenolic chemical resistant coating for floors offers heavy duty protection.

  • EPOXY – protection against acids, alkalis, solvents, caustic fluids, fuels, fatty acids, salt or sugar solutions, chemical cleaning detergents and more
    Uses: on concrete metal and wood; common on flooring in in the food and drink industry, garages, factories, and plants.
    Cons: a tendency to weaken with high or fluctuating temperatures, lack of flexibility, not good with UV radiation (thus an indoor coating)
  • POLYURETHANE resistant to organic caustic fluids, acids and alkalis, fuel and hydraulic oils, and solvents
    Uses: where greater flexibility and an ability to deal with high temperatures is needed, the preferred choice of chemical resistant coatings in the dairy industry where there is exposure to lactic acids
    Cons: Soft, likely to abrade, extremely sensitive to humidity during application, lower chemical resistance than epoxies have
  • PHENOLIC – resist 98% sulphuric acid, hydrochloric acid, transmission fluid, gasoline, formaldehyde, phenol, and numerous other chemicals also in high temperatures
    Uses:  for tanks, ducts, piping, immersion service for most acids, solvents, and salts (chemical storage), flooring in healthcare, science, technology and electronics industries, as well as chemical and waste treatment plants, pulp and paper mills, and power generation plants
    Cons: non-resistant to some strong organic acids and solvents, and the less epoxy used in the makeup of the coating, the less resistant to chemicals it is
  • FLUOROPOLYMERknown for non-stick, but also highly resistant to a wide range of chemicals, including concentrated sulphuric, nitric, hydrochloric and phosphoric acids in temperatures up to 300°C
    Uses: where a low coefficient of friction or a lubricious surface is required, for use on concrete or metal in secondary containment linings, acid plants, fertiliser plants, oil refineries, and more
    Cons: poor weather protection characteristics, and cannot withstand acetone, esters, ketones, and acetic acid
