Scrape Off The Rust

Small-town Minnesota company offering big-time metal maintenance

While the world is slowly becoming active again, the financial implications of COVID-19 remain. In particular, construction projects have ground to a halt due to safety concerns for workers, supply chain issues, the tabling of state financing incentives, and rising municipal bond rates. Luckily, one American company makes a product specific for this issue.

When projects are cancelled mid-stream or after materials are purchased, concerns about rusting metals become a reality. “HinderRUST”, a rust prevention product made by Minnesota-based Fluoramics, offers project managers and fabricators a variety of solutions for maintaining the integrity of metals. It’s among the products we’ll be highlighting in our newsletter as a supplement to our June Product Showcase, available in the next print issue of Electrical Apparatus. Below, a before-and-after of a bolt treated by the product is pictured. Skeptical of anything besides WD-40 for this purpose? See how it stacks up against other rust treatment products.

Whether the metal is stored flat sheets, rebar, girts, purlins, or fasteners, “HinderRUST provides a long-lasting boundary film between metal and moisture, and is easily applied by sprayers, aerosols, rollers or brushes at any stage of construction,” the company said in a May 28 press release sent to EA.

Fluoramics offers three versions of the product, as well:

  • R2.0, which is a short-term, removable version that is “ideal for metal parts that are manufactured and waiting to go into service, or that will need to be painted.”
  • S4.0 is the standard version for use on metals under cover and is designed for equipment maintenance, electronics protection and pre-assembly protection. S4.0 is also weld-through approved.
  • HV100, a heavy-duty version for extreme weather conditions. It will thicken over time and provide a thin wax-like barrier of added protection. 

As an added benefit, the product lubricates while it protects against corrosion. That means nuts/bolts, anchor bolts and other hardware can remain workable while waiting to be installed.

Fluoramics, Inc. is a manufacturer of sealants, greases, lubricants and rust inhibitors, all of which are engineered PTFE solutions. Founded in 1967, the company is based in Winona, Minnesota, a city of under 30,000 people near the southeast border with Wisconsin. Flouramics “proudly manufactures all of its products in the United States,” the company stated.
