Achieve high performance protection with Indestructible paint
What do the Pentagon, truck bedliners, oil platforms in the Tasman Sea, and bulletproof vests have in common? The answer is indestructible coating. Indestructible coating is renowned as a viral sensation when a group of Australians coated a watermelon with it and dropped it from a height of 45 metres. Amazingly, not only did the watermelon not shatter, it bounced. But indestructible coating has so many more uses than fruit protection. Originally developed to protect vehicles, indestructible paint has applications 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 New Zealand.
How is indestructible coating so indestructible?
Indestructible coating is a proprietary blend of a coating known as polyurea, created by the company Linex. Though the precise formula is kept under wraps, the coating is essentially a blend 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 American Central Intelligence Headquarters, The Pentagon, has its exterior walls coated in order 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.
6 Benefits beyond indestructibility
Not only is indestructible coating robust, it also brings many more benefits to a project. Because of the properties of the coating and its application, indestructible coating also provides:
- Efficient return to service time – touch dry in seconds
- High abrasion resistance and impact protection
- Chemical resistance
- A watertight and airtight monolithic membrane – prevents corrosion
- No cracking, splitting, or warping
- No VOCs, no CFCs, no solvents
How to apply indestructible paint
Indestructible coating is hot sprayed onto the substrate, drying in seconds to minutes. The process is time sensitive because, once the two components are combined, the reaction begins immediately and irreversibly. The two components are pressurised then pumped into the hot spray gun through heated hoses. They are combined and sprayed at the same moment. This means that there is 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.
A few of the most common uses for indestructible coating include:
- Secondary containment and bund lining
- Roofing membranes
- Car park decks
- Light plant and machinery
- Truck bed lining
- Boat decks ramps, and cargo holds
- Silos and feed containers
