When it comes to choosing a protective coating for different surfaces around your house, there are several options available in the market. One such option for increasing the lifespan of various surfaces is anti-corrosion paints. Versatile and resilient, these paints can be a perfect solution for your maintenance needs. Anti-corrosion paints can be used on various surfaces for protection against rust and other similar corrosive factors. Here is everything you need to know about anti-corrosion paints.
Types of anti-corrosion paints
There are different types of anti-corrosion paints available in the market that serve different purposes. Here are the main types.
Zinc-rich paints
As the name suggests, this type of anti-corrosive paint is largely composed of zinc particles that provide superior protection against corrosion. This type is best suited for protection of steel surfaces.
Epoxy paints
This variety of acrylic paint with added epoxy combines the characteristics of superior adhesion and durability with resistance against chemical corrosion. These are mostly used in industrial settings on metallic machinery.
Polyurethane paints
Commonly known as PU paints, this variety is made from synthetic materials. A protective layer of PU paint provides resistance against harsh environmental and weather corrosives such as UV rays and moisture. The application of PU paints is very vast, ranging from home exteriors to marine industries.
Alkyd paints
Alkyd paints are a variety of oil-based anti-corrosive that is composed of polymers combined with fatty acids. Their USP is superior protection against moisture but their use is limited to industrial settings.

Where are anti-corrosion paints used?
Anti-corrosion paints play a very crucial role in increasing the lifespan of surfaces and therefore, their applications are very vast. Here are some of them.
Marine industry
Ships and other forms of marine transportation face constant exposure to harsh environments like saltwater and turbulent weather conditions. However, the inevitable corrosion caused by these factors can prove hazardous and even fatal. Therefore, anti-corrosion paints are used in this industry to protect the metal parts from harsh environments.
Infrastructure and construction
Anti-corrosion paints are used on bridges and tunnels to increase their longevity, especially in case of steel. These infrastructural elements need to be protected against the exposure to harsh weather conditions in order to maintain their strength and durability.
Automotive industry
Automotives are exposed to several kinds of corrosives when on the road like road salts, dust and moisture. Therefore, metallic parts of automobiles such as the undercarriage need to be protected from corrosion to ensure the health and safety of the same.
Oil and gas industry
Infrastructure of the oil and gas industry such as pipelines and storage tanks can easily get corroded due to high-speed flow and other factors. Anti-corrosion paints are used to protect them against these kinds of corrosives.
Household applications
Several metallic surfaces found in households also require protection against corrosives. Anti-corrosion paints can be used on gates, fences, railings, metallic furniture and tools to prevent them from getting corroded or rusted.
Why use anti-corrosion paints?
Let’s have a look at the benefits of using anti-corrosion paints.
Increased lifespan and durability
Anti-corrosion paints maintain the structural and compositional integrity of metallic surfaces by preventing it from collapsing due to the action of corrosives. This also leads to increased longevity of the surface, making it a long-term investment.
Low maintenance
Since these paints form a protective layer over surfaces, there is no need to worry about repairs of damages caused by corrosives. Apart from occasional reapplication of the protective coatings, these surfaces require little to no maintenance on regular basis. This leads to cost savings on this aspect.
Aesthetic value
The actual appearance of metallic surfaces tends to get distorted due to corrosion and rust. Not only do anti-corrosion paints prevent this kind of distortion, they also enhance the aesthetic appeal of the surface.
Safety and performance
In case of infrastructural and industrial settings, anti-corrosion paints are an indispensable resource for ensuring functionality. They protect the basic structure of machinery and improve their performance for better outputs.
Anti-corrosion paint cost
Here is a list of per litre prices of anti-corrosion paints of some popular brands.
| Brand | Price per litre |
| Asian Paints | Rs 200 – 300 |
| Berger | Rs 180 – 350 |
| Dulux | Rs 400 – 500 |
