Mark Jackson Posted October 1, 2020 Share Posted October 1, 2020 I've tried to find out what type of casting resin is used by the likes of Aires, CMK, True Details, Verlinden, Resicast etc. I think there is more chance on being invited to afternoon tea with the Queen. Does anybody know and will I have to perform some bizarre ritual where I swear a pact to have carnal knowledge with a goat? dodgem37 1 Link to comment Share on other sites More sharing options...
Iain Posted October 1, 2020 Share Posted October 1, 2020 Hi Mark, Can't answer for the resin manufacturers per se, but are you after the specific resins each of them use? Or just a general recommendation? On a personal level I get excellent results with G26 Polyurethane casting resin in the main, which gives me good results for a variety of tasks. But you may already have knowledge of that, if so ignore. Now, about the egg whisk and a frozen chicken, on a full moon... Iain Link to comment Share on other sites More sharing options...
Mark Jackson Posted October 1, 2020 Author Share Posted October 1, 2020 Hi Iain (nice to see the Scottish spelling with an all important "i"). I used to cast parts a few years back but was never 100% sure if the resin type was similar to that used by model accessory manufacturers. Polycraft slow set 15min, paintable polyurethane resin in RTV Silicone moulds lined with a light dusting of baby powder in a pressure pot at 50psi.

Bob MDC Posted October 1, 2020 Share Posted October 1, 2020 Hi Mark, No goats or bats but "eye of newt and dragon spawn " a bit different. The problem is there are so many on the market and some are not the best rule of thumb if it smells it's crap !!! it is a polyester smells, brittle and destroys moulds. I've been using the same stuff for over 25 years Polytech silicon various grades, the even have one with a 8 minute pot life and 30-40 min demould. Two types of silicone condensation cure normally a 10:1 mix the moisture in the air helps curing which is the standard rubber mould or addition cure which is normally translucent 50:50 mix and a slight bit of heat helps. Resin a minefield for the unwary so many companies selling the same stuff in different tins. One company sends me a sample of their "new" resin which is the same stuff from many years. My own poison is Axson now Sika F38 or F180 these do about 95% of our work the other 5% is a bit complicated stuff. To make things easy I have used one supplier since I started and through a strange twist we both started our companies on the same day. So call Neills Materials https://www.neillsmaterials.co.uk/ and they are based in Bury St Edmonds!! If you get in touch and ask for Tom, Chris, Russel or Justin mention Bob at MDC resins and rubbers. please contact me if you have and questions or need any help.

Mark Jackson Posted October 2, 2020 Author Share Posted October 2, 2020 Thanks Bob Years back I bought some smooth on resin, then read the bit tucked away on their website about not being able to paint it. Link to comment Share on other sites More sharing options...

Bob MDC Posted October 2, 2020 Share Posted October 2, 2020 Mark nearly all of the resin now will take paint now, I think I remember the product you are talking about and at that I will say no more Best way now is wash the resin parts in warm soapy water,dry the a clean with isopropyl alcohol and then prime, I use Mr Surfacer Primer Surfacer 1500 straight from the can I've been treating masters/3D prints and castings for a "few" years and it's not let me down.

Thunderbolt Posted November 15, 2020 Share Posted November 15, 2020 (edited) yes, as a follow up to this, if one is planning to use a vacuum chamber, what is the best resin/silicone to get for casting parts at home? Working in the CONUS, but could probably do an international order. thank you Edited November 15, 2020 by thunderbolt1988 Link to comment Share on other sites More sharing options...
Bob MDC Posted November 16, 2020 Share Posted November 16, 2020 No need to go abroad Polytech can get you all the stuff you need. https://www.polytek.com/ I've been using Polytek rubber both the condensation and addition cure for over 25 years they are the best in my opinion it depends on what you want to do on the rubber choice, on the resin side my normal bulk resins are European but due to the S*$t S*%"w at present I have been trialing other resins and Polytech Easyflo 60 is the best by far only the cost to me in the UK stops me from using it as my primary resin I have trialled it to all my customers and none of them could tell the difference . On home use depending on what you are doing I would be looking a 5 kgs rubber and 2kgs (1 plus) for resin as my unit buy. If you need any more info just drop me a line.

Mark Jackson Posted November 16, 2020 Author Share Posted November 16, 2020 I've been casting and the results are laughable, but acceptable for my own projects. Neils-materials said they were too busy to deal with me so I used a company in Northern Ireland. Link to comment Share on other sites More sharing options...
Bob MDC Posted November 17, 2020 Share Posted November 17, 2020 Mark, Sorry to hear you had problems but we are in strange times if I can help in any way let me know, when we moved to LIncolnshire a couple of years ago I found a box with my first model castings I think I have moved on a bit. But if I can help please ask. Bob Link to comment Share on other sites More sharing options...
