After rewatching this a year later I'd be very curious why you don't "need" a flow medium? In all vacuum infusion videos with disposable vacuum film you need to use a flow medium above a release film. Is this simply a matter of speed? Or is the geometry well suited here? Or is the silicone stiff enough to not get sucked into every single fiber and seal it off? Thanks again for the video!
Dear Dejay, this is the starting point of an interesting discussion! If you'd like to dig deeper on technical aspects of the process, I'd suggest you to reach our tech team via our website contact form: bit.ly/Elkem-Contact
@@daltanionwaves I think breather cloth is for vacuum bagging only. They actually do use a flow medium here, the black netting like material but only at the bottom. I also learned that if you use scored and perforated foam core that works as a flow medium (and increases bonding to foam)
@@dejayrezme8617 Part of the answer is that, as with many silicone bag infusions, they use glass mat instead of cloth of multiaxials, which is much more permeable to resin.
Hello, Is this product obtainable in the USA? Who are the sellers? Can I buy retail, online? I am only a hobbyist but this product would certainly work for me.
Dear, you can contact our experts directly here: goo.gl/vvdHM2 If it's for your personal use, they will probably connect you to our distribution partners in the USA!
Yes, absolutely! Our slow curing version (RTV3720 SC : goo.gl/QNWDqA) Is perfect for brushing! You can contact our experts for more information here: goo.gl/vvdHM2
@@ElkemASA - That's really good to know, 'cause I have a one off project that may turn into something more, and I want to be prepared for that possibility. Plus, I just hate the idea of wasting so much time fiddling with the bags. Those RVB's are just such an elegant solution, one that occurred to me (lucky for me, they already exist). I'm aware of another company that has a spray gun with a price tag that makes no sense to me. I assume the spray gun I saw in this video would similarly be out of my price range, too bad 'cause it's a better solution. However, for the small project I have in mind, a brushable material will fit the bill. Unfortunately, the link to RTV3720 SC didn't work, but I found it through a Google search. I did a search for it on your website, but it wasn't found; the Google link got me there.
@@tsrjs What great news! Would you like to get in touch with one of our experts or distribution partners to exchange on your project and get some silicone advice?
@@ElkemASA Thanks for your reply, sorry I missed it. I don't UA-cam very well. Just now realized I had some comments waiting. Regarding the RVB's, looks like for my one-off project, that's a little bit too ambitious. I've got about a dozen parts to infuse, and the RVB, even the brush-on would make my project prohibitively expensive. Since the majority of the parts are fairly flat, I believe standard vacuum bag material will suffice. For those parts that have more curvature, I believe the Stretchlon 200 will meet my needs. Again thanks for your interest.
can I just use some of those silicone tubes one buys in the shops? like for bathrooms and stuff`?
Making such a messy job look so clean. Superb attention to detail. I bet even that guys work car is clean every day. Impressive.

a.
By flow medium do you mean 'breather cloth'? ... It does appear to flow very well although it's not real-time video so it's difficult to know exactly.

Can you also brush on the silicone to make the bag instead of the special spray machine?
