Silmar 1421 Resin.

I was looking at some threads for Silmar 1421 resin, does anyone know if this contains UV catalyst or inhibitor?


It can be bought with UV catalyst and optical brightener. Ortho/Iso hybrid is stronger but is hard to get if you are in southern Cal since it is illegal here. If you have connections you may get it in Santa Cruz where the laws are more relaxed about its’ sale…

Thank’s for the reply Oneplus!

Its tricky to get over here too…Have you tryed it? Whats the optical brightener about?
