Resin based "spackle" for use with Dibond decks in case interiors.
In Tools & Materials
Oct 20, 2023
Not polyurethane really more of a two-part epoxy-type product more related to the old school Pliacre and then Phillyseal type products. Like bondo only passing oddy tests. Specifically interested in a formulation that would kind of self-level instead of being too "doughy". Especially interested to see if anyone has used a product in this kind of capacity. I don't have photos because I am enquiring on behalf of another organization unfortunately.

You have it right. There is a lack of consistency between different brands of rigid PVC boards. Sintra has passed Oddy tests going back a couple of decades at some museums. One product that was recently tested and did very well is Komacel (I believe they did testing beyond just the usual Oddy tests also) it is made by the same company as Komatex so it can be confusing. Komatex pretty consistently fails tests for use in case interiors.

For my fairly simplistic applications, I have been using Apoxie Sculpt or Fixit (another AVES product that typically passes Oddy tests). That is not exactly an earth-shattering revelation but I did hear an interesting answer to a question I have always wondered about in an AIC/CCN Materials Working Group meeting recently. You know the small tubes of epoxy putty you see in home improvement stores put out by J-BWeld? There are a bunch of varieties. It turns out that one of them (called SteelStik) has been passing Oddy testing! I don't know if any other version does or not but SteelStik is one that is stocked in most hardware stores in my area. Kind of cool to know that if out of the blue you need a same-day source of inert epoxy there is one that is likely to be readily available!

Pam, It actually should be mentioned that your conservator's reaction is totally logical. My first reaction to seeing the product in use in 2004 was "Hold it this can't be right"! I was taught the same thing about good plastics and bad plastics. Having had the good fortune to work at/for three museums with extensive testing programs in place an equally shocking truth to discover is how often Polyethylene products (especially foams) fail testing miserably! If you are using "Ethafoam - type" products to rehouse artwork in storage assuming your objects will be safe you should know that "Ethafoam" is like "Kleenex" also. Distributors may tell you that what they sell is the same thing but from their perspective but it often is from our perspective. I had to deliver the bad news to a small museum that the polyethylene foam a medium-sized museum had stockpiled and was using in storage should be reserved for non-storage purposes because it failed testing in such a big way! Cushioning performance in packing and crating is also an issue with substituted products as cushioning curves really do vary to a surprising degree.

In discussions in the MWG we recently covered the use of Sintra and other rigid PVC foam boards. The material has been used and tested many times at the Getty where it has been in for something like 20 years now. At a meeting on materials held in 2015 at the Lunder Conservation Center housed at the Smithsonian American Art, the topic came up and what became clear is that all PVC board is not created equal. The markets for which the material is really designed are not concerned with off-gassing. The material has many advantages but selecting the right specific product is key. I would recommend that you consult the AIC Wiki for test results from different institutions and the entry at CAMEO for application hints. Other than Sintra brand other brands that have tested well are Komacel (not Komatex) and e-pvc (although the latter may have had a name change). No matter what you buy insist on receiving an SDS just to confirm the manufacturer. Sintra is to PVC board as Kleenex is to tissue. Distributors will often substitute products that are indistinguishable figuring they are doing you a favor!
