Lets talk about Resin.

[Uruk-Hai]

Hello!

I would like to hear your advice, experience and preference when it comes to Resin.

I have been casting a bit, using different kinds of Resin from Sylmasta, which Im quite happy with.
http://www.sylmasta.com/acatalog/Sika_Casting_Resins-1.html

They have some differences in potlife and viscosity but all has the cream yellow finnish and are a bit hard or crispy. They can of course be coloured but looking at the options I find it a little bit expensive.

I have seen the green greyish Resin used be manufacturers such as Tommys War and SK Minatures which I as modeller rather work with. As its easier to spot detail and easier to carv, saw and sand. I wonder where that Resin is to be found for my own casting purposes?

So what do you guys prefer to work with?
And those of you that cast, what do you prefer?

Cheers

Hi Janne,
I am using Sylmasta G26 and G27 at the moment, to get it grey just buy one pack of G26 or G27 Black, use this to colour your normal G26/G27 by adding about 10g of the black part A to the full can of beige part A and shake well. This will last you for a long time as you only use 10g to colour a whole 2Kg kit. If you want darker or lighter grey just adjust amount added, obviously better to start with less black and work up to the colour you like.
Not sure why you are getting hard or crispy castings, what temperature are you casting at, room Temp should be about 20-25 degrees celsius.
I also mix my Sylmasta by equal parts by weight using digital scales.
Hope this helps
Steve

Same here as Steve, black mixed with part A, and mixed well.

Thats a good tip. Thanks a lot for the help.
Im casting in room temperature but it usually get closer to 25 than 20.

I have meassured by the help of grade disposable cups? If to use a scale, how exact does it have to be?

Can I also ask you how you feel about the longer pot lifer for G28?

Cheers

25 is a good temp so no problem there.
If using scales if mixing very small amounts of say 20g of resin you should be accurate at 10g part A and 10g part B, sometimes with larger quantity of say 100g or more a couple of grammes either way will not have any adverse effect. A set of small kitchen digital scales are very cheap, I normally pay around £10 for a set in the U.K and they do the job just fine.

I have no experience of using G28 so cannot comment there, I always use fast pot life which in hot weather can be down to as less as about 20 seconds but I can still pour,vacuum(twice) in that time but I have a vacuum pump that will get the chamber down to full vacuum in about 5 seconds.
