Alright, I just got off the phone with Aquaresin, and it alll sounds VERY promising.
I grilled their rep for process information and explained VERY thoroughly how we would be using their product, and what our process is. It sounds like a perfect fit.
Heres the scoop:
Aquaresin is a resin substitute that is mixed by adding a non-toxic liquid material to a non-toxic powder, typically in a 1 part liquid to 2 parts powder ratio, although more powder can be added for increased thickness (bondo-like consistency). He likened it to mixing 'pancake batter' The liquid and the powder are purchased seperately so that you can always use the rest of whatever you have more of leftover.
Aquaresin is more expensive than polyester or urethane resins, by about half. The prices can be somewhat confusing due to the liquid/powder being sold seperate and being measured differently. So you can't just ask for 'a gallon kit', you have to order the liquid and correct amount of powder to go with it. The prices he quoted me were about $16 for 1 quart of liquid and $16 for the correct amount of powder to go with it which makes a $32/half gallon kit. I should think that 1/2 gallon would be enough to resin a helmet, from a mold or pepakura. He also said that the prices drops the more that you order at once..
I discussed the possibility for a discount with him at great length, and he said that we might be able to set something up, but because we were spread all over the country and would be ordering seperately that would complicate the issue. If we were to place large bulk orders and have them shipped to one primary location and re-distribute them ourselves a discount may be possible. We'll have to work out the logistics of that if we want to pool our money for a large bulk orders in the future.
Aquaresin needs to be reinforced with fiberglass (although I'm sure that muslin cloth can be used too Ruze). He said that fiberglass cloth or mat can be used and actually that the mat would be stronger than the cloth. Aquaresin markets their own fiberglass to go with their resin, at lower cost than most other brands. The resin can be built up in layers, a layer of fiberglass can be put down whenever the desired thickness is reached, then sealed over. Aquaresin can be cast into rubber or silicone molds. Unlike polyester or urethanes Aquaresin DOES NOT SHRINK when it cures, meaning that the cast parts will be virtually identical to the originals in size. Aquaresin could also be used for pepakura, although the paper models will need to be sealed as Aquaresin is a water based product that would absorb into the paper and warp it as it cures. So we'll have to find the best product for sealing the paper models prior to resining them. Something like an aerosol clearcoat or sealer should work.
Aquaresin has distributors in : California, Florida, Massachusetts, New Jersey, New York, Pennsylvania, Vermont, Washington State, Canada, and Australia. He said they will soon be distributing to the U.K.
He's sending me a trial kit to test out so that I can test it out and report the usefulness of this stuff to you guys. When it comes in I'm going to run it through a full battery of tests, casting it, laminating pepakura with it, sanding/drilling it and I will thoroughly document and photograph the whole process for everyone and post it here. He said that if other members wanted to get trial kits to do the same, that they would have to negotiate that with their closest supplier, he couldn't send out dozens of these kits to different members of the same organization. But he was so impressed with the number of our members (and possible customers to him) that he really wants to work with us on future bulk and/or discount orders.
This is awesome!!! Personally I know that I'll be switching over, and I think we should spread the word. Their rep said that one of their customers is a company called 'Costume Armor' in New York... anybody know who that is? I figure if a professional costume armor company is using it... it should work for us!
What an incredible find Spartan267! Way to make an entrance!
