Re: rust converter

I wash it off before painting.

Re: rust converter

Ask ko lang po kung gagamit ako ng TURCO Rust Converter kailangan pa bang linisin ng soap and water after applying rust converter o diretso ng i-apply ang epoxy primer.

You definitely have to wash off the crystalline deposits.

Re: rust converter

definitely need to be wash but you have to use steel brush also so that all rust are gone..

Re: rust converter

Rust Converter is a synthetic polymeric formula that converts existing rust into a moisture free, black protective coating. Not only does it eliminate existing rust, but it seals out moisture to prevent the possibility of future rust formation and corrosion. Surfaces protected with this primer and an oil based paint resist the effects of weather, sunlight, rain and even salt spray without peeling or cracking as long as the oil based paint is maintained per manufacturer's recommendations. Rust Converter provides an excellent base primer for oil base and epoxy paints. This easy-to-use product is the first step in providing long-term protection of steel and iron surfaces.

Meaning, you dont have to steel brush the area coz the rust is already converted to another form that protects. But, I will still clean all the areas with a mild soap and water solution.

Re: rust converter

In using Turco or other rust convereters as surface preparation before priming, do you guys dilute it?

Re: rust converter

Ask ko lang po kung pwede iapply ang rust converter sa stainless steel tube? I used a stainless steel tube and its accummulating moist that looks like rust. A supplier suggested to apply it with turco. Once applied how long po and effectivity ng turco? tnx

Re: rust converter

to clarify things here...

once the metal is dipped over the converter and turns black, you DON'T have to remove the black formation? tama ba?

in my case, i don't. as i understand it, that is already part of the protective coating.

Re: rust converter

i also noticed,sometimes there forms some hard white deposits after turco or cord turbo has been applied to the surface. what's this? should this be removed?

Re: rust converter

In my field of work, we have been using phosphoric acid as regular as we use water. Let me share what I have learned and continuously adopting related to rust converters:

1. Most commercial products claiming to be rust converters have been marketed and reported to transform non-protective types of iron oxides and oxyhydroxides into more protective oxides. Most are proprietary formulations, but it is generally known that phosphoric and/or tannic acids are frequently used as their main constituents. Since their inception rust converter or rust transformer performance has always been under scrutiny. Research has been done on both phosphoric and tannic acid as a catalyst for rust transformation. Tannic acid is believed by some to cause the transformation of non-protective oxyhydroxides into magnetite.

2. Stainless steel is not stain-proof but it stains less because of chromium. Yes, TURCO can remove the stains if these are caused by corrosion.

3. Better to wipe-out (not necessarily flush-out with water) crystalline (magnetites) formation for smoother surface refurbishing

4. Depending on the rust formation, TURCO will become effective only after an hour. A second or third application is necessary if rust formation is dense. Immediately paint or cover the surface, if not, you will be surprised after a day, rust will form again. This is because of our humid environment.

5. When you apply rust converters to a RUSTY steel, crystalline formation will appear to show that proper chemical reaction took place. If you applied this to a metal and none appears, either the "rusting" is not being caused by FE203 (ferrous oxide/oxidation) or your rust converter just "stained" black your metal (hydroxide film). This, based on my experience, can be painted over.

Re: rust converter

where do you get phosphoric acid locally?

Re: rust converter

where do you get phosphoric acid locally?

Industrial (machine, external foodline maintainance, workshop) type - from Chemphil, also imports JT Baker Brand

For food application, acidulant of syrups & drinks - JT Baker

If you mean retail, check Purechem & Newchem

Re: rust converter

I converted from Turco to Bronco brand.

Re: rust converter

Pwede po ba ito gamitin sa sasakyan? Paparepair ko yung truck namin at medyo may kalawang na yung ibang parte, Paano ba gamitin ang turko? May nakausap ako pintor dati ang experience nya sa turko ay mas mabilis daw magkalawang pag ginamit nya ito, baka lang mali ang application nya.

thanks
