Devcon Plastic Steel 10110 changed recently?

So that's interesting, I wonder if what comes in the syringes and small tubes is the liquid steel version (does not seem to be see below). I would say it's normally a bit thicker than JB weld but definitely thinner than the putty, I haven't used the tub/putty stuff for a long long time.

Smaller versions I've seen of the "Devcon Plastic Steel" that is thinner than the putty version. Might just be time to move to marine tex.

.

Definitely seems like there's product variation for sure. Have to do some digging, I had assumed, seemingly incorrectly that the versions above were similar to the liquid 10210 version, but it appears to not be the case by the specs.

The 10110 Putty appears to have a compression strength of 8200 PSI and the Liquid 10210 of 10,200 PSI both with the same listed shrinkage and tensile strength of 2800 PSI. The two other versions list 2500/2600 PSI tensile strength, but I could find no info on shrinkage or compression strength.

So this is where the rabbit hole gets really odd.....


The two smaller products above tube/syringe, share the same name. However, I found an old 2008 data sheet on the syringe version (#62345) that states that it does NOT have steel in the mix, and that if steel filled product is desired to use #52345 (the 2 tube version shown above) or #45209 (I could not find any info on this # related to devcon). It also indicates that it's made by permatex. That's almost 20 years ago so who knows what the difference is today. That said I have some guns bedded with the syringe version for 20+ years and seem to be holding up fine.

So to add info to this I contacted ITW, and inquired about the 4 various products. I was told that the "home" version(s) of plastic steel epoxy are developed/marketed by ITW Global as opposed to ITW Performance polymers the industrial side that manufacturers and markets the Devcon 10110 and 10210 products.

So it would appear they are possibly completely unrelated products. I did get contact info for ITW Global so I'll try to get more specs on the "home" versions of PlasticSteel. The contact they gave me appears to be tied to permatex, so it would seem they are still making these other "Devcon" products with the Plastic Steel name. I'll reach out to them and see if I can get more info from them on these "home" Devcon Plastic steel products for comparison.

I can say that it definitely appears that the 1oz/syringe products are vastly different and produced by Permatex. If you go to ITW global, they list Devcon Home products, but when you click on it it just takes you to Permatex's website which does not list any of the Devcon Home products on it. In addition if you click on the SDS sheet page from ITW Global for Devcon Home, it takes you to the SDS sheets for ITW Performance Polymers and they do not list any Devcon Home products only 10110 and 10210.

However I was able to find SDS sheets for all 4. It doesn't give info on what we'd really like (compression strength and shrinkage) but it does list ingredients. That said much like a recent thread on gun cleaning solvents it's clear by looking at older SDS sheets, the formulation changes often.

The syringe 62345 version lists the following ingredients in it's resin. (2018 SDS from vendor)

• 40-70% BISPHENOL A/EPICHLOROHYDRINBASED EPOXY RESIN
• 10-30% Limestone
• 7-13% PHENOL, POLYMER WITH FORMALDEHYDE GLYCIDYL ETHER
• 1-5% ALKYL GLYCIDYL ETHER

The 1oz tube 52345 version lists the following ingredients in it's resin. At some point it would seem they removed metal from this version's resign. I've seen older SDS sheets that list metal in the ingredients for it. (2022 SDS from vendor)

• 15-40% BIS[4-(2,3-EPOXYPROPOXY)PHENYL] PROPANE
• 3-7% AMORPHOUS SILICA
• 1-5% BENZYL ALCOHOL
• 0.1-1% CRYSTALLINE SILICA

Devcon 10210 plastic steel liquid (SDS from manufacturer site)

• 40-70% Ferrosilicon, [with >= 30% But <= 70% Silicon]
• 15-40% Resin:--reaction Product Of 25068-38-6Bisphenol A And Epichlorohydrin(refer To Epichlorohydrin)
• 0.1-1% Fiberglass fibers
• 1-3% Other components below reportable levels

Devcon 10110 basically the same as 10210 but with different ratios (SDS from manufacturer site)

• 60-80% Ferrosilicon, [with >= 30% But <= 70% Silicon]
• 10-30% Epoxy Resin:--reaction Product Of EPOXY RESIN 25068-38-6Bisphenol A And Epichlorohydrin(refer To Epichlorohydrin)
• 0.1-1% Fiberglass Fibers
• 2.5-10% Other components below reportable levels

Just looking at the above it seems likely that neither of the Home versions are likely anywhere near as good as as 10110 and 10210 products.

Also interesting, ITW Performance Polymers also appears to manufacturer Marine-Tex. Funny that we often hear Devcon 10110 vs Marine-Tex debated and the same company manufacturers both.
