What is Flash Rust? Can Seal n Peel Control It?

Flash rust is one of the biggest problems in the oil and gas industry.

We are well aware that rust and corrosion by themselves pose a costly problem to industries, none more forceful than with the oil and gas industry. However, Flash Rust maybe even trickier a tide to stem. By its name alone, flash rust is the sudden appearance of corrosion on a massive scale. It can happen without warning and rust over a metal surface in just a few hours, often without anyone noticing anything until too late, unless seal n peel products can control it.

Attempting to stop – or at least minimise – rust and corrosion has always been a sore focus point for the oil and gas industry ever since the U.S. Congress ordered an investigation over a century ago pertaining to rust. So, imagine the pain that flash rust may cause when workers suddenly discover a vital metal part or piece of equipment that looked fine a few days ago is now covered in surface rust. Flash rust is tough to predict and contain because of a variety of factors.

How Does Flash Rust Occur?

Flash rust often occurs after metal parts or equipment have been through intense cleaning methods such as wet blast cleaning or water jetting. The time window between the cleaning and the air-drying is when flash rust occurs.

The question most people will pose is, “Why use these cleaning methods if metal surfaces become vulnerable to rust?” By default, water blasting methods are the most accessible – and less costly – methods of cleaning usually available. In some cases, there is only limited cleaning time, so more detailed cleaning methods like pickling and chemical stripping cannot be engaged.

Another factor to consider is that environmental conditions like humidity or moisture vapours may cause flash rust to suddenly appear on certain steel surfaces. This is most obvious with equipment exposed to wet areas. Even in dry conditions, flash rust can appear on steel surfaces if the metal is exposed to chemical contaminants or moisture toxins.

Metal that is also left exposed without any anti-rust protection will speed up the cause of flash rust. This is why Unituff 452 (formerly Seal’n’Peel 452) is essential as an anti-rust protective coating.

A most frustrating fact: Companies that use traditional anti-rust protection like thin paints and anti-corrosion oils will not be able to stop flash rust. Unituff 452 Seal’n’Peel offers the best protection against rust because its heavy-duty membrane-like coating seals off the metal from any creeping rust or moisture.


Investing in long-lasting rust prevention is the only way to fight flash rust. But what if flash rust already has begun to show on a metal surface? Unituff 452 Seal’n’Peel is a polyvinyl chloride copolymer solution coating that can be applied directly on top of flash rust. This eliminates much of the equipment downtime, cost, and labour needed to prepare steel surfaces for traditional paints or oils. Also, Unituff 452 is easily applied by paintbrush or spray, and just as easily removed by peeling off by hand.

To combat flash rust, the oil and gas industry really cannot find anything better than seal n peel Unituff 452. When a company is ready to make flash rust a thing of the past, just contact Unituff for enquiries or to request a quote at https://unituffglobal.com/.
