Home-Made IEMs - Page 100

post #1486 of 2208

why not uv acrylic? it's cheaper, less messy, easier to work with, more durable, prettier and so on. Try to walk properly before learning how to run, though I have to admit there're less specialized equipments involved when working with silicone.

egger LP and Loctite are UV curing acrylic and that's quite big difference.

They are silicone,I read them drom egger and loctite catalogue.

I'm sorry but you've probably miss read it. I've just checekd their catalog LP is UV acrylic. There's no UV curing silicone in the egger shop. Please see the catalog again https://egger-labor.de/enplace/1101/files/E_Katalog_2013_web.pdf

 

Also check loctite 3684 info: http://deweb02.henkel.com/henkel/adhesives/Product%20Approvals.nsf/03e34d770c41d3ab802572f1005551f8/382ca8eae080635e8025734d0050dc5b?OpenDocument Clearly says Acrylic UV

http://ebookbrowse.com/lt3380-resinaid-brochure-pdf-d19077253
at page 9/16 the 3596,3680,3584 says SOFT,UV.

At page 176 your 2013 egger catalog writes " Also suitable for soft UV-materials (LP/W)." you can find that sentence with searching.

also egger 2010 catalog:

http://egger-labor.de/enplace/1101/files/E_Catalog_2010.pdf

at page 136; LP/W soft UV polimerising.

I hope you saw where you missed.

Still these aren't silicone. Of course there are some different types of acrylics mostly used in Hearing Aid industry - these "Soft" materials are plastics/polymers they are meant to avoid cracks and breaking if say hearing aid fall out of ear. Westone uses something similar for their canal part of IEMs - they use Dreve Termosoft (my guess) there's also Dreve VarioTherm - both of these are heat-activated - they are getting soft after you put it in your ear, and you can't break them.

 

I went through Loctite catalog and it says that 3596, 3680 and 3584 are "Acrylate Urethane" not silicone (page 8 and 9)

From UV/Moisture curing silicone there are 5083 and 5084 only (Modified Acetoxy Silicone)

post #1493 of 2208

Great idea, already started working on it. Googling for information on DIY UV chamber smile.gif

post #1494 of 2208

Lots of info here, so after all this... what is the best product to use, weighing up pros and cons; cost, minimum purchase amount, curing methods etc? I like the idea of the UV material, but which one!? theres seems to be so many?! ha

It actually doesn't matter much which one you use. Loctite, dreve, egger works good as long as you use them well. Just be sure to get something skin-safe with ISO or CE.

No, it won't. It's a modeling paste - it has really heavy consistency think of tooth paste. You need more liquid material or silicone.

hello again everyone, 

 

what aboout this product? http://www.ebay.co.uk/itm/Jesmonite-AC300-Non-Toxic-Water-Based-Acrylic-Casting-Laminating-Resin-4Kg-Kit-/320808990930?pt=UK_Crafts_DrawingSupplies_EH&hash=item4ab1b4b8d2

 

the guy who made the instructable about the iems used acrylic casting resin and coated it in nail polish to make it inert i guess?

 

What do you guys think?
