Mountmaking Forum ›Plascoat or vitroguard


I'm a freelance mount maker at The Met, Guggenheim, and the museum of arts and design in New York. At MAD we use a pulverized plastic that is thermo sensitive. You heat up your brass wire, dip it in the powder, then the plastic coats the wire, and finish by heating the powder coated piece. It basically melts and creates a soft plastic coating. Anybody ever heard of this product, or are using it? I'm looking for a source for it and want to order more. I think it's called vitroguard or vitro gaard it's also labeled plascoat. I see it's been oddy tested and passed. I also see on the aic wiki that is called vitroguard 12 plascoat. Anyways. Looking for a source. I've written the plascoat company but am waiting to hear back. If anybody has leads for me I'd owe ya one. Johnny



Last source I had for Plascoat Vitor Guard 12 Natural is from  2006  not sure if it is still good.

I was never crazy about it since it was hard to control,but others liked it alot.

Hi Johnny,

We brought in a barrel of Plascoat from Punda Merchantile a few years ago and shared it with our mountmaking brothers and sisters. Since then Punda is no longer the north American rep. and no longer carry it. I have a small canister of Plascoat that I guard jealously, it isn’t a coating for all occasions but when it’s appropriate it is wonderful.

Good luck in the hunt.




I don’t believe Plascoat brand Vitroguard is still available.  I have tried Glaslok powder and it seems to be the same type of material. WE HAVE NOT ODDY TESTED IT!  I have just been experimenting with it to see how it flows when heated, adheres, etc.

Yes. The fabled barrel of vitroguard. I remember the story now. So it is true! Nice to read of its origins. Such a good story. Anyway, yes I've written to both of those addresses yesterday but did not try to call. Haven't gotten an email back yet so maybe I'll just call them. 

Pretty much what we have here is how far I've gotten, Internet sleuthing. 

Wish me luck. Maybe we can all pitch in for a new lucky barrel!




Just got off the phone with plascoat. It is still available! Ask for mike. 



That vitroguard is so good I use it almost for everything! I even coated the tips of my calipers so I would scratch any artifact!Thanks for the update because I'm running low also.

There used to be a thermoplastic coating product that started with the letter "B" followed by a number. Anybody heard of / remember that?

Is it acryloid or paraloid b-72? I have yet to use it but I've read a lot about it.

  • I need to make custom mounts for rocks, #10/5kg and bigger, fast. What I need is a way to make a quick 'prototype' shape, that will mimic the rock, and that I can use to bend the steel to. The present rock is kinda diamond shape, 12”x 9” x 2” / 30x22x3cm thick, and of course need to balance on a corner, so the big flat face fronts. I am making a mount for it, but want to be able to do them ‘mass production style ‘ for lots of rocks, all different, sizes and balance points. I need to be at able to make custom yet fast  This is a commercial rock shop. No time to make ‘duplicate rocks’ They want steel mounts, it’s their preference. Any and all ideas will be appreciated!
  • Hello all. Over the years I've had occasional mounts that required steel over brass. Because I don't have any welding rigs and am only using acetylene for brazing, I've always just brazed the steel. I've noticed that it takes a lot more time for the joint to flow properly with steel. My question is, what's the limitations when brazing is no longer enough? Can stainless be brazed? I'm wondering if it's time to expand and get a welding set up. Any recommendations on welding equipment would be welcome as well! Yours, James
  • For those of us that have been working with institutions their whole careers but have always wanted to break out on their own to avoid...certain politics shall we say, or certain salary limitations. Do the mountmakers here that are independent have any sage advice to offer such a person? Like me for example? I've been doing the side gig thing for 13 some-odd years now so I already have a good reputation and client base but I know there will be surprises and challenges coming up really soon. My last day at the museum is September 6th, so it's time for action man to take action. I'd love to open up some dialog on these ventures as well as the current state of institutions (i.e. protests and unionizing at major institutions lately). Love to hear from you all. yours, James Spark and Anvil
