Environmental Resin [info dump]

Aug 11, 2012

    1. A new resin has appeared in the hobby. It has the translucent quality of French Resin but is very UV-stabilized. Doll owners say they do not observe any yellowing a year or two into owning the doll.

      Most of the info mentioned on DOA seems to be translated from Chinese. Sometimes it's "environmental resin", sometimes it's "Canadian resin". Some sources say the supplier is French. But environmental resin is not French resin.

      Anyway, here's what I got trying to find out what it is.

      The ecopoxy mentioned above seems to be this stuff.. It has youtube videos demonstrating how to use it.

      And then I found this:
      http://detail.china.alibaba.com/buyer/offerdetail/72951712.html
      The picture of the bjd hand seems to match descriptions on DOA. The name of the resin is FC911 made by Motichem, which they say is a Canadian company (but I can't find info on Motichem except as a dissolved company in the UK). I'm convinced this is the thing they say is EV, though. Here's a page I found introducing it and demonstrating its reproduction fidelity.

      Has anyone here used it before? I know batchix did her Machina dolls in environmental resin but she doesn't say brand and model.

      I'm pretty far from casting myself, but I thought this might be useful for other people out there.

      Please, if anyone knows anything at all about this new material, share it!

    2. I was trying to find out more info about this a while ago but back then came up with nothing. This Motichem company seems to be pretty good with hiding itself from the public, don't know what's up with that. From looking at those photos you found I'm trying to figure out the address of the company and I think it's something like "Motichem advanced material Inc, 250 Consumers Rd NY. Ont. L3R (8P2?) Canada" But idk about that, that postal code doesn't seem to coincide with the street address so far as I can see? And the web address is www.motichem.ca but that brings up nothing as well. Maybe asking the companies who use this product for Motichem's contact info would work, if they'd be willing to divulge that info.
       
    3. The blog (spider toys) with the demonstration I linked to claim to be the official agent for this product. They have a taobao store that sells it, and the taobao store ships from Beijing. When I google the product name, there are many suppliers but ALL the results are in Chinese. The product doesn't seem to have an online presence in English. I did find an alibaba place, though (alibaba is an ebay-like exporter, so they would ship internationally).

      It could be that a Canadian company designed it for a chinese client who specified it for BJD uses. The SGS sheets at the bottom of the blog post say Test Report and list soluble heavy metal test results for cadmium, lead, etc and the test location is listed as being in Guangzhou, which is an import city (so the product being from Canada is plausible).

      Someone asked a question in the comments on the blog post and from that you can infer the environmental resin is twice the price of some other "regular PU". If we get it from China we might be paying for things to be shipped from Canada to South China, then from South China to North China, then from North China to us...orz. It would just be best if we can get it straight from Canada >_<

      Another possibility is this could be a shanzhai product -- pretending to be from Canada. If it is shanzhai, then the strange address format and nonexistent website would make sense.

      What *other* environmental resins are there?

    4. Whatever the caster for Jpop dolls uses (Chinese) it sure looks like what is being described - it is slightly translucent but not French and the tests for yellowing done by Kaye (mentioned in a post on resin cafe somewhere) showed very stable characteristics. I have several KW dolls as well as Lydia snul cast by this co. The resin is lovely. When I advertised a kw doll for sale and described it as French resin, grace from jpop corrected me and said it was not French.
       
    5. Cerisedolls has used a thing she called bioresin, and it has a french supplier that she uses. In conversation with Cerisedolls twigling mentioned a supplier in the UK. Cerisedoll's bioresin seems to require a pressure pot. Further reading needed on this material?

    6. I've never asked Weiju, the company i use for casting, much about the resins. I would think that would be proprietary knowledge. They do call the environmental resin, "american" resin and the other resin "japanese" resin... so they might be importing it from North America somewhere. It's very, very durable. They string my dolls extremely tight and the parts don't warp at all. I've had a few ankle chips, but that's it. It ranges from being very translucent to more opaque. Lagoon is their japanese resin but the machina are all environmental resin.

      All I supply Weiju with is my original doll and a sample of the color I'd like them to cast in. I use Task 9 from smooth-on, which isn't environmental resin. It requires a pressure pot to cast with, but it's super durable and i can add mica powder and glitter. And... I'm kind of an addict for that kind of thing.

      I might give that eco-poxy a try when I get resettled in my new place and the lab gets re-set up. I wonder if it has the strength to hold up to compression without warping? That's been an issue for me with alumilite and polytek in the past.
       
    7. My question is: what is the test for compression strength (for any material)?

    8. Ringdoll and Blueblood Doll both say they use Motichem resin: "Ringdoll products is made of MOTIchem Canada ecological and environment-friendly resin which is especially created for dolls and figurine (no Xylene and perfectly harmless to human skin and respiratory system)."

      The label on the jug, in the photo, says it's marketed to the industry. Maybe that's why it doesn't seem possible to buy it except through industry suppliers?
       
    9. There seems to be some major misunderstandings going on. I'm talking to the Motichem chinese online rep. As far as I can see they're calling it Canadian because the type of resin seems to originate in Canada, like Aran sweaters are not always from Aran...

      And then their agents (like spidertoy) are simply not correcting their customers when their customers assume it is import.

      And then, also:
       
    10. I was researching this a while back and learned that basically Motichem is made in Canada, but the sole distributor is in China. Motichem is the rebranded name, I don't know what Canadian company it comes from (I found a website that I suspected was the source, but they of course do not mention Motichem). It would be awesome to buy and use Canadian environmental resin, especially since I live in Canada, but I think this is a dead end. Unless the source company is actually willing to sell to other distributors, the only option is to get it from China, or have someone in China do the casting for you.
       
    11. Wow thwts interesting penguu. I do recall grace from jpopmsaying the resin they use was their own special blend...
       
    12. Could you tell us how you learned this? I wasn't at all able to find which Canadian company made it.
       
    13. I had emailed BlueBlood Doll with some casting questions a while ago, since their dolls are (or were at the time, I don't know about now) made with the Canadian Environmental resin. I was hoping for a better resin to use than Smooth-on, but, really, I don't think casting is a thing I can do well.
       
    14. glimmer, I'm not really sure "own special blend" means much when we're talking about plastics. It's not like these casting companies can make their own plastics from petroleum or plants. They have to start from somewhere...a somewhere that is the same for all plastic-end-users. If they can find it, so can we...
       
    15. Perhaps it's a matter of using two different resins, and doing something like mixing together half and half of both resins' part A, and then half and half of both resins' part B, and then mixing those mixes? I dunno how well that'd work (if at all).
       
    16. Currently I am researching the same exact thing. I read the "Ringdoll" advertizements and also Jie Dolls uses it in china Blueblood dolls uses it and ISland doll uses it and advertizes it on thier ebay site and thier website. Im also trying to track it down. we must keep tracking because someone knows something . Island dolls does casting for other artists in this 'Environmental Resin" as well. Are there any updates on this information?

    17. Patricia, Ringdoll and Island both use the motichem FCS911.
       
    18. I don't know whether this is the same thing you guys are talking about, but there's something called aqua-resin (called jesmonite in the UK). It's pure white, and can be coloured with dyes. I've recently visited one of the distributors in the UK, and he confirmed it's ecological and totally non-toxic. (As oppose to smooth-on, which put his friend into a hospital). The sample looked pretty good, very smooth and tough. But the best thing and the reason why I was initially so interested in it is doesn't actually require de-gassing with vacuum chamber. Has anyone used it? Perhaps you could tell me if it's worth trying it out, I don't know how suitable it would be for bjd. I am currently working on a head sculpt that I want to cast using this resin. If no one has any feedback I'l try it anyway, and report back on the results :-)
       
    19. aquaresin has quite a bit of info online, Nia, it is definitely not the same thing as the environmental resin that prompted the investigation in this thread. I think AquaResin is mostly a laminating resin used in combination with fiberglass. I've seen cosplayers use it to make armor.
       
    20. Thanks for clearing that up Penguu, as I'm a novice at resins. But that AquaResin/Jesmonite looked pretty interesting anyway. It doesn't have to be used in combination with fiberglass. I went to the distributors and they were just then demolding a (Jesmonite) bust from a two part silicone mold. It looked good, so I think I'll give it a go, when I am ready for casting. That's the only viable solution I've thus far found to not using a vacuum chamber for resin. And that is a major problem for me. I'll let the forum know how that experiment goes. They also had something called BioResin, it's clear but can be dyed. I thinks it's a lot more expensive though, and it still needs "vacuumiing". Sorry if this isn't relevant.
       
    21. Nia,

      If the aqua resin turns out to be a keeper, it would be good news for all of us! Keep us posted! (Maybe open a new thread, though, since your resin is pretty unique. I would love to see what you've learned about it. Pictures, maybe?)

      Bioresin I think has been mentioned earlier in the thread. I think Cerisedolls from our forum was bio-resin...?

      In any case, I'm pretty convinced that when Chinese doll companies say the words Environmental Resin, they mean the motichem FCS911 stuff, which is maybe (unconfirmed) formulated by a Canadian company, but all the distributors are Chinese (confirmed).
       
    22. Ha, as a person from Hong Kong, I would probably choose Bio resin over that Chinese thing.
      I'm waiting for the supplier to stock, and would like to ask if they would ship to Hong Kong.

      One simply cannot help but being skeptical towards Chinese websites.
