Sugru mouldable silicone rubber
« on: September 10, 2013, 03:22:43 PM BST GMT »
I picked up a pack of this stuff in B&Q (DIY store in the UK) today. It is an air setting silicone rubber compound. It was quite expensive (£8 for 5 5g sachets), and at first I thought it was an epoxy putty. However it is actually a silicone and sets to a typical flexible silicone rubber.

It got me wondering if it could be used for making (very small) moulds, possibly for press moulding or cast small resin parts. It is only tempereature resistant up to 180c so I don't think it would survive white metal casting...

Tried it ages ago.  Did I post about it here?

Yep...

The stuff on the knife collet broke off, but the pin vice is still nice an' comfy. ;) I still haven't made any tools with it, though. (ditto the teflon)

The idea of moulds crossed my mind too, but I wonder if it's altogether viable with the price and amount of the stuff. Personally, I might sooner try instamold or similar. Once I've used up my siligum...

Pinkysil havea similar product, pinkysil putty that you hand mix. Haven't used it but would be excellent for push moulds. Also could be used as two part molds if you wanted, a bit more expensive though for that application. Less messy though.
