Effectively protect surfaces from substances with chemical resistant paint

Almost all coatings will be exposed to chemicals and acids 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 paint or acid proof paint is 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 protective coating, solvents, acids, alkalis, salts, and other substances can be absorbed by the substrate, causing deterioration and contamination.

The right chemical resistant paint or acid proof paint is the one that satisfies the requirements of the chemical, as well as the needs of the substrate. Choosing correctly requires fully understanding both. Whether you need a hydrochloric acid resistant coating, sulfuric acid resistant coatings, fuel resistant coatings, or chemical resistant paint for steel, there is a product for the job. Therefore, we start with providing you with the 5 factors that help you choose the most suitable chemical resistant paint.

  • 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?

In this article we will explain the different chemical resistant paint options, and provide a guide to help you choose the right one as well as where to find products and contractors in the Emirates.

The 4 main options of chemical and acid resistant paint

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

1. Fluoropolymer

Fluoropolymer based chemical resistant paint is suitable for example for machine component.

Non-stick, high temperature (300°C) chemical resistant paints: wide range of chemicals, including concentrated sulfuric, nitric, hydrochloric and phosphoric acids

Applications: Normally used where a low coefficient of friction or a lubricious surface is required. Suitable for use on concrete or metal in secondary containment linings, acid plants, fertilizer plants, oil refineries, and more.
Downsides: Fluoropolymers have poor weather protection characteristics, and cannot withstand acetone, esters, ketones, and acetic acid.

2. Polyurethane

Resistant to organic caustic fluids, acids and alkalis, fuel and hydraulic oils, and solvents

Applications: Where greater flexibility and an ability to deal with high temperatures is needed, polyurethane is the traditional alternative to epoxy. Polyurethane is also the preferred choice in the dairy industry where there is exposure to lactic acids.
Downsides: Softer than epoxy coatings, polyurethanes are more likely to abrade. Extremely sensitive to humidity at application. Less resistant than epoxies.

3. Epoxy

Protection against acids, alkalis, solvents, caustic fluids, fuels, fatty acids, salt or sugar solutions, chemical cleaning detergents and more

Applications: An unprotected concrete floor can quickly deteriorate through exposure to chemicals, particularly flooring in the food and drink industry, garages, factories, and plants. Having a floor that can withstand these exposures is important to prevent bacterial contamination. Chemical resistant epoxy paint is suitable for metals, concrete and wood.
Downsides: The drawback with epoxy coatings is a tendency to weaken with high or fluctuating temperatures, and it is not as flexible as polyurethane. They are also not good with UV radiation (which causes it to chalk and fade), and can be stained by chemical attack.

4. Phenolic

98% sulfuric acid resistant coatings, also resistant to hydrochloric acid, transmission fluid, gasoline, formaldehyde, phenol, and numerous other chemicals also in high temperatures

Applications: Protective coating for tanks, ducts, piping, immersion service for most acids, solvents, and salts (chemical storage). Applicable for flooring in healthcare, science, technology and electronics industries, as well as chemical and waste treatment plants, pulp and paper mills, and power generation plants.
Downsides: Not recommended for exposure 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.

Chemical resistant coatings manufacturers and products UAE

With so many different environments and surfaces that require chemical and acid resistant coatings, it is no surprise that the range of products and services is extensive. There are the coatings above, but there are also specially formulated coatings like methacrylate, which cures at low temperatures and is used for cold-store and freezer rooms. Below is a table outlining some of the available products, with price indications (subject to change and variation). It is these coatings from reputable chemical resistant coatings manufacturers like AkzoNobel that contractors trust.

A chemical resistant coating should be applied by a trained professional to ensure an effective and flawless application. Fortunately there are many coating installer companies operating in the UAE.
