Harry72,
Dunno, have yet to use it. Figured it could be back tracked via the UN number.

ThanksCheers

I am by no means an "expert" on casting polyester resin, however I have a background in industrial chemistry (paint industry) and have been reading extensively on the subject of casting PR for pen blanks.
PR resin for surfboards is not suitable for the purpose of casting, it is designed to cure in relatively thin layers. What you need is a PR resin specifically designed for casting, that cures properly in relatively thick sections and doesn't shrink excessively.
One source for this PR casting resin is Diggers (avaialble from hardware stores, such as Bunnings), about $20 for 500 grams.
A better, and cheaper, source is Barnes. They stock 2 PR resins for casting as well as the MEKP catalyst. The cheapest PR casting resin from Barnes is Quality Casting Resin , is designed to be mixed with extenders and pigments, either dry or pre-dispersed in a suitable medium (usually DPM). The other resin they supply is clear casting resin usually used for embedding.
Barnes also supply metal powders, extenders such as talc, slate powder and mica, as well as Pearlex pigments.
I have visited their Richmond-Vic store and it is veritable treasure trove for casting supplies.
If you want more reading on PR casting, there are some very good articles in the library of the IAP forum, also has articles on how to set up a pressure/vacuum pot.

Thanks BS, I was wondering about the thickness and cracking/overheating.
So just plain old casting resin... should've known KISS!....................................................................
