The high performing and strong protection that is: indestructible coating

What do the Pentagon, truck bedliners, oil platforms in the Pacific, and bulletproof vests have in common? The answer is indestructible coating. Indestructible coating came to fame as a viral sensation when a group of Aussies coated a watermelon with it and dropped it from a height of 148 feet. Amazingly, not only did the watermelon not shatter, it bounced! But indestructible coating has so many more applications than fruit protection. Originally developed to protect vehicles, indestructible coating has uses in sectors; from heavy industrial and agricultural to marine and offshore.

In this article we will describe the incredible properties of indestructible coating, how to use them for your project, and where to find this powerful coating in the US.

Why indestructible coating is indestructible

Indestructible coating is a proprietary blend of a coating called polyurea. Though the exact formula is secret, the coating is essentially a combination of an isocyanate and a polyol resin. The polyol works like a plasticiser, and when the two components are combined they react to form a long chain molecule. It is these chains that are responsible for the coating’s indestructible properties – all tangled up together, they make the coating hard and impenetrable, but because the chains can stretch out and return to place, it stays flexible. This gives the coating incredible tensile strength and tear resistance.

One of the best examples of this strength are the coating’s use in military applications. The Pentagon has its exterior walls coated to protect the building and its occupants from shrapnel, the main cause of injury in an explosion. It is also used in bulletproof vests to catch and contain bullet fragments when the bullet breaks apart on impact.

More than just indestructible – 7 other advantages

Not only is indestructible coating strong, it also brings many more benefits to a project. Because of the properties of the coating and its application, indestructible coating also provides:

  1. A fast return to service time – touch dry in seconds
  2. High abrasion resistance and impact protection
  3. Chemical resistance
  4. A watertight and airtight monolithic membrane – prevents corrosion
  5. No cracking, splitting, or warping
  6.  No VOCs, no CFCs, no solvents
  7. Approved for use under Regulation 31 of the Water Supply (Water Quality) Regulations

Applying indestructible coating

Indestructible coating is a hot sprayed polyurea, which dries in seconds to minutes. The process is time sensitive because, once the two components are combined, the reaction begins immediately and irreversibly. Because of this, the coating is applied with a special spray gun. The two components are pressurised then pumped into the gun through heated hoses. They are combined and sprayed at the same moment. This means that there are only seconds from the moment of spraying to having a dry surface.

The ease of application and desirable qualities of the coating mean it finds applications in all industries from agriculture and machinery to marine and military sectors.
