Hello folks. 

I'm fairly new to the composites game, having only really used epoxies to create glassy finishes on work surfaces so far. 

I'm currently making some prototypes, and want to create a piece of cast resin which will diffuse light similarly to commercially available polycarbonate diffusing sheets. 

I'm hoping to use standard casting resin, a silicon mould/other form and an additive. 
I've read that there are silicon-based products that may be able to achieve this effect, but haven't been able to ascertain if this is the case or what I'd need to use. 

Any help appreciated! 

Cheers, 

Ren
