Casting in resin, what do I use?

[MJI]

I want to resin cast some parts such as axle boxes, battery boxes, gas cabinets, seats, and other components,

 

I have moulds made with Scarva rubber and they hold the detail well.

 

I will also be using this technique with other things later (eg DMU roof dome, possible whole roof).

 

So what is a good one to use please?

 

Want about 250g or so

Hi Martin,

 

Is that a total of 250g mix, or 250g of hardener and 250g of resin?

For making rather larger castings, I currently use a filled electrical potting epoxy resin (trade name here Technirez). Whilst not specifically designed for the purpose it is easy to use, strong and takes detail very well. Sufficiently well to perfectly reproduce brush marks in the mould release agent if I'm careless enough to leave any. Might be worth trying to track down the UK equivalent.

No idea just a rough idea of approximately what I THINK I may need as I have 300g of mould rubber

In the past I've used a product called ALUMILITE with good success, its a 1:1 mix and cures very quickly.

I think this is still the best historic thread for resin casting discussions 

http://www.rmweb.co.uk/community/index.php?/topic/101778-starting-out-in-resin-casting/?hl=tiranti

 

As you can see I searched on a supplier "tiranti" it helps clear out the many hits discussing resin kits etc

Funny really but that is where I had found the rubber but COMPLETELY forgot that thread

 

Ooops!!!!!!!!
