Casting Materials
« on: July 27, 2009, 06:26:24 AM »
Hi, I'm doing some research into the different types of casting materials used for casting and re-casting tools and scene marks. Currently using Isomark for the majority, also Permlastic and Silcoset. Anybody use anything different?
Looking to reproduce high levels of detail with a rapid cure-time.
Many thanks

We have used Mikrosil for quiet a number of years and have had good success with it.

I have had very good results with a product called Coe-Flex (Coe Laboratories).  It is less reflective than Mikrosil and has the advantage of being available locally at dental supply companies.  It is a polysulfide offered in different consistencies. We used injectible, the thinnest.  You may be able to find it or a comparable product locally.

Many thanks for the replies, we have also used Mikrosil with good results, although I have not heard of CoeFlex. I'm in the UK so will have a look at the availability of similar dental materials here.

Forensic Sil from Forensic Source would be my vote.  It is much like mikrosil but the mixing and application is 1000X better.

I'm with Travis.  Forensic-Sil is the only way to go!  May be a little higher in price than some (maybe not as I don't know what the others cost) but you will get you money back two-fold in time saved. 

No clean up involved and no waste!  Can be easily applied without getting it all over everything (unlike Mikrosil  :) ).

Quality of the cast striae is on par with Mikrosil.

we use both Forensic Sil and Mikrosil

I like forensic  sil better. it is so much easier to use.   however, it's a good idea to:

A) remain proficient with mikrosil ( make the trainee's use mikrosil before forensic sil)

B) Keep some mikrosil on hand for thse times when you are in the middle of a case and you run out of applicator tips!!
