Styrene safe paint stripper

[Buntobox]

Hi

I'm making up a paint stripper that will strip enamel and acrylic paints from polystryrene models. After a bit of research into what's already out there I have come up with a mixture of isopropanol and butoxyethanol. It strips paint very effectively, quickly and doesn't harm the styrene, so job done. However I have noticed that these two alcohols tend to separate after a while when mixed together and I have heard that dimethyl carbonate prevents this separation. Question is, how much do I need in my 1:1 mix of IPA and BOE for it to do this?

 

Regards

I think you have to test it. Also to Check if Dimethylcarbonate dont harm the poly styrene.

I would start with 10 %.
