Cutting oil ( Suds) resistant paint

[Andrew BinningParticipant @andrewbinning37010]

Can anyone recommend a paint that will withstand cutting oil or suds. I have used Hammerite in the past but that seems to peel after a time. Rust Oleum paints have two part epoxy paints which might do the trick but they are expensive and come in industrial size packaging.

Rebuilding a milling machine and need a paint that is suds resistant.

I repainted my "Donkey Saw" a few years ago with Berger household paint because I had some and it was near enough the grey colour required.

The machine does not get a lot of use but the paint is standing up well to the suds oil.

I assume this was an oil based paint intended principally for woodwork?

I've used Blackfriars QD 90 paint for many years without apparent issues with synthetic coolant. See no reason why it shouldn't be suds resistant too. Best to give it a few days drying time. Data sheet says 3 days to harden fully, I'd double that. Its not petrol or fuel oil proof tho'. Primer adhesion isn't the best against impact or scraping unless you are meticulous about surface preparation and cleaning. Its OK but Vapormatic is better

I'm told that Vapormatic Agricultural and Machinery paint is good with oils and solvents too. One day I'll finish painting my P&W lathe with it. The bits I've done are holding up well after nearly 10 years but they aren't heavily exposed.

When I re-furbished my Myford many years ago I stripped to bare metal, undercoated and then spray-finished with Myford's own touch-up enamel. The result seemed fine and durable until relatively recently when the frequently handled areas have been affected, I think, by my regular use of PR88 hand protection.

Does anyone know what Myfords use today?

Automotive paint? It copes with folk dripping petrol and diesel around the filler areas fine

I was watching this video a while ago, where "automotive car paint" is used by a professional machine rebuilder.
From 18.40 but the whole video is worth a watch; as is most of that channel.

Yes I still have the tin of "Squirrel Grey" from 7 or 8 years ago. Berger brand oil based, I did not want to throw money and loads of time at the saw but it is proving to last well enough.

Hi Andrew

Stationary engine paints sell all machine tool enamels on line in small half litre or one litre tins

primer as well

Hi Andrew,

I use Johnstone's Trade Smooth Metal Paint on all my machines. Brilliant stuff. Check it out on the web

[Phil WhitleyParticipant @philwhitley94135]

+1 for Paragon paints from Stationary engines, but also Tractol from your local Agri engineers is good.

[StueeeeParticipant @stueeee]

I've used both of these paints with good results, they're both available in any RAL or BS colour, and both seem to go on OK with a brush or a spraygun.

Arcforce

Tractol

Usual disclaimer, only a satisfied customer etc.

During my years in machine tool manufacturing we experienced numerous times when coolant reacted with the finish in coolant tanks. We used two pack epoxy on the machines themselves but used specialist coolant equipment suppliers for the tanks etc. We never had a problem with the machines and I don’t know what caused the reaction with the coolant tanks but some coolant acted like paint stripper. If you know what coolant you intend to use then do a test with, paint a bit of metal and submerge in neat coolant to ensure it is compatible.

Alkyd resin paints are resistant.

Myford did use Trimite Q58 which is a polyurethane based formulation. Before that Masopar by James Mason (Nottingham Rd, Derby, no longer trading).

Tekaloid paints are a supplier of paints, so called coach enamels (= transport). Again Alkyd resins, they also make Tractol. T&R Williamsons of Ripon area family owned firm producing a very wide range of paints, for machinery, transport (trains etc).

Other paint makers also exist.
