Everything You Need to Know About CARC Paint

CARC paint is a special type of paint developed by the United States Armed Forces. Unlike other paints, it is not only about providing finishing to metal surfaces but making metal surfaces highly resistant to chemical and biological warfare agents attack.

What makes CARC paint so special is its non-porous nature. Most paints are porous in nature. And, when applied on metal surfaces, gives absorbent metal finishing ( ). But CARC paint provides non-absorbent metal finishing and makes it ideal to be used for tactical military vehicles on the battlefield.

How CARC paint is applied?

The process of painting a military vehicle with CARC is a four-step process which involves cleaning, pretreatment, priming, and topcoat. Let’s have a look at it in detail.

Step 1: Cleaning

The first step in any painting job is cleaning. The surface of a vehicle is cleaned thoroughly with soap and water to remove any dirt present on it and allowed to dry. It is necessary to clean the surface thoroughly before painting to ensure that paint adheres properly to surface. Dirty surfaces do not allow paint to make a strong bond with the metal surface which makes paint peel much earlier than if applied on the clean surface.

Step 2: Pretreatment

Standard wash primer treatment is used for pretreatment. The purpose of pretreatment is to improve adhesion of subsequent coatings and provide temporary resistance to corrosion. Pretreatments should be applied as soon as possible after cleaning. And, it is highly recommended to wait for drying to complete before applying primer.

Step 3: Priming

After cleaning and pretreatment, the metal surface is given a primer of epoxy. This primer coating makes metal surface corrosion resistant. An additional coat of epoxy polyamide enamel is applied over the epoxy primer on the interior surface. The purpose of the primer is to protect the metal surface underneath against corrosion.

Step 4: Topcoat

At last, a topcoat of polyurethanes is applied on the vehicle's surface. Polyurethanes are used only for exterior surfaces of a vehicle. It provides the camouflage and makes vehicles surface resistant against chemical and biological warfare agents. For interior surfaces, epoxy is used.

Advantages of CARC paint

CARC paint is a special paint which offers the following advantages:

•  It is easy to decontaminate. It is a non-porous paint. Therefore, fewer contaminants are going to adhere to the surface of the vehicle. It makes decontamination cheaper and easier.

•  It is non-absorbent and makes vehicle’s surfaces impervious to chemical agents and biological warfare agents ( ). It prevents the transfer of harmful agents to military personnel who come in contact with these surfaces.

•  It is a superior camouflage. It includes the unique pigment package that can easily confuse infrared technology. A military vehicle can go undetected and blend better with the surroundings.

So, this was brief about CARC paint.
