The easy-to-apply and environmentally-friendly RustPrufe corrosion protection solution for non-porous surfaces eliminates the need to repair damage to steel surfaces occurring during extended storage periods or shipping and handling.
The solution is ideal for industrial and mining applications, and is available through wear control specialist, Filter Focus. A wear control specialist at the company notes that 'RustPrufe is a painted or sprayed-on acrylic polymer emulsion that dries to form a seamless, skin-tight weather and UV-resistant protective barrier.
"Items such as valves, gears, shafts, and motors are often subjected to harsh climatic conditions, and RustPrufe is the most convenient, cost-effective and user-friendly option to ensure that these costly components are not damaged in transit," he explains.
The specialist points out that the components do not have to be sanded down or rust treated. "Upon application, the product is peeled off by hand to reveal a clean and rust-free surface. As a result, cost savings during routine maintenance and repair shutdowns are tremendous."
Unlike traditional tape, wax and oil coatings that must be scraped off and cleaned with solvents, RustPrufe does not leave behind a residue. It is also highly-durable and,should tears or perforations appear, they can be closed by applying the coating to the exposed area with a paintbrush.
Onsite components are often exposed to aggressive environments and require continuous efforts to maintain. The specialist highlights the fact that RustPrufe can also be applied in these applications as a permanent anti-corrosion coating on operational equipment.
"RustPrufe is also acid-resistant, and has been successfully used to protect electric motors in acid plants on numerous South African mines. The solution is also utilised in the fertiliser industry, where it is applied on earthmoving machinery to protect it from nitrates that eat away at the metal," he adds.
RustPrufe is also environmentally-friendly and with zero toxicity leftover,the coating can be disposed of safely in landfills. "With no harmful chemicals, PPE is not required and an absence of harmful vapours and fumes means that the solution can be applied in confined spaces too," the specialist concludes.
Filter FocusSA(Pty) Ltd was formed in January 2002 with the aim of establishing the concept of combination filtration and eliminating contamination related wear and failures in heavy industrial equipment.
