Chemical resistant coatings protect concrete and steel from being damaged by corrosive chemicals or acids. These are used in industries such as power generation, manufacturing, mining and processing.

These types of coatings need to be able to withstand harsh chemical attacks from cleaning products, spills or fumes. They also need to be able to resist different concentrations at varying temperatures. Different chemicals require different levels of resistance, as a coating can lose its effectiveness if exposed to a different concentration or temperature than what it was designed for.

Defending Against Corrosion: Exploring the World of Effective Chemical Resistant Coatings

A few examples of chemical-resistant coatings include phenolic and epoxy-based coatings, fluoropolymers and silicones. Phenolic and epoxy-based coatings are heavy-duty chemical-resistant coatings, offering protection from a variety of chemicals including sulfuric acid, hydrochloric acid, transmission fluid, gasoline, formaldehyde and phenol. These coatings can also withstand high temperatures and are suitable for use in chemical processing plants, power generation plants and wastewater treatment plants.

While these coatings are strong, they can also be aesthetically pleasing, providing a range of colours to liven up an area from the traditional plan grey concrete look. Chemical resistant coatings also provide an effective barrier between concrete and steel, preventing the penetration of chemicals into the substrate, which can cause damage over time. This helps to prevent the need for costly repairs and maintenance work. Chemical-resistant and waterproof coatings can also strengthen a concrete structure, lengthening the lifespan of the surface. These benefits make them a cost-effective option for the majority of industrial environments.
