At ETNA Products Inc., we recognize that not every part that is machined will go immediately to the next process on its way to creating a final product. Newly machined parts are especially susceptible to corrosion and rust because of their fresh, unprotected surface. If these parts are to be stored or even shipped after machining, manufacturers rely on corrosion protection either via in-process inhibitors that leave an imperceptible thin film once the machining operation is complete, or via long term films applied after the machining process. ETNA Products Inc. offers rust preventives that provide anywhere from a couple of days of indoor protection to 24 months of outdoor protection.
Why use an in-process corrosion inhibitor? To protect the metal components of the machine, the tool, as well as the finished part. In-process corrosion inhibitors are water-based and therefore are low VOC and typically compatible with the metalworking coolant being used. Once water evaporates, the film left is invisible to the eye. Although traditionally applied via the coolant itself, water-based in-process preventives can also be applied via dip tank or spray.
Why use rust preventives for short or long term storage? Parts that are machined are especially susceptible to rusting. Job shops machine specialty pieces that required storage or even shipment to another shop for further processing. Further processing can be within the same shop, down the street, or across the country. The part is not in its final state and ready for a permanent coating so rust preventives are utilized to provide a temporary barrier film to protect that freshly machined surface from rust. Short and long term rust preventives can be applied via dip tank, spray, or brushing. Thinner film products that are invisible are utilized indoor and can offer storage protection from 3 months to 2 years. Thicker film products are visible and are meant to offer more permanent protection. They are utilized for outdoor uncovered protection for 2 years or more.
