Flycut rusty surface4/30/2023 Results indicated most of the rust were dissolved and transformed with the reaction of phytic acid and rust on the rusty carbon steel graphene could effectively improve the compactness and protective performance of the epoxy surface tolerant coating. electrochemical impedance spectroscopy (EIS), polarization curve, and salt spray test were used to evaluate the corrosion resistance of low surface treatment coatings. Scanning electron microscope (SEM), X-ray powder diffractometer (XRD), and infrared (IR) spectrum were used to confirmed the iron rust conversion performance by the reaction of phytic acid and rust. 3Hubei Huaqiang Technology Co., Ltd., Yichang, ChinaĪ graphene modified epoxy surface tolerant coating was prepared, and the corrosion performance and rust conversion mechanism of the prepared composite coating on rusty carbon steel substrate was investigated.2Key Laboratory of Marine Materials and Related Technologies, Zhejiang Key Laboratory of Marine Materials and Protective Technologies, Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences, Ningbo, China.1School of Petrochemical Engineering, Changzhou University, Changzhou, China.Water based products set up hard and inflexible and will eventually flake and peel on top of oil based coatings.Xiaoping Guo 1,2, Hao Xu 2, Jibin Pu 2, Chao Yao 1*, Jing Yang 3 and Shuan Liu 2* The reason is that oil based coatings don't set up completely hard but remain somewhat flexible. You can use oil OVER an water based coating but not the other way around. If you already have an oil base coat like Penetrol, you can only use an oil based product on top of it. It's made for ships and equipment but a friend uses it to coat canvas floorcloths and says it lasts for years in high traffic areas and under tables and chairs. It's pricey ($100/gal?) but incredibly tough. You might also talk to someone at a Sherwin Williams store about SherClear. At the least, you should use several coats of polyurethane. It's prone to lots of impacts and abrasion. INDUSTRIAL STRENGTH POLY A table top, specially a work table or dinning table, is a pretty tough environment. This post is only about preserving the beauty of rust while stabilizing it to make a rusty object useable and not so messy. please don't ask me how to repaint your car or patio furniture. I'm just a guy who, by chatting with an old time paint guy, stumbled onto a way to stabilize and preserve rust without hiding it. But if you don't have rust, you can skip the penetrol and just go straight to the polyurethane. I wrote this about protecting and preserving the rust for it's looks. I've also been getting a lot of questions about clear, un-rusted metal. The polyurethane is a good, stable, long-lasting finish that won't easily wear off. The reason I use the polyurethane top coat(s) is that the Penetrol is a linseed oil product, and as such, is not very hard or durable. So far they look just like the day I finished on all my projects. I've used this method for several years now including on towel bars hung with damp towels everyday and for a countertop under my bathroom sink. Even on the perfectly flat surface it didn't leave brush marks.ģ) I always spray on a mat polyurethane top coat or two for a smooth finish and the finished piece looks completely natural. I just rinsed it off with a hose on saw horses, let it dry in the sun thenĢ) applied the Penetrol with a brush. In the case of the steel vanity tops shown in the intro I left one out in the rain for a week to cover some scratches and wanted to preserve the light layer of rust. For a rusty surface I'll usually clean it real good with water and a soft brush or cloth to get any dirt off. )ġ) I usually wipe down the piece with paint thinner to remove excess dirt and oil but since the product is oil based you don't need to remove every last trace. I chopped it up and added some numbered steps. It yanked the post and sent me a note to mend my ways. (I originally made this a single page post since it's basically just a product recommendation but "the Bot" didn't like that.
