The Mouldmaking & Casting Forum

Hello all
I am new to this sort of forum but thought someone here may be able to help me.
I am trying to polyester resin pen blanks for makining the barrels for hade made pens. I have been told to use the clear polyester resin but i a wondering what would be the best product to use to colour the resin and then what to use to make different coloured swirls through the base colour.

any help would be appreciated
Cheers Ian

Clear Casting Resin is still the most economical resin used for this purpose.It has a nasty smell and does not agree with everybody but use in a well ventilated area it works well. You need to buy the MEKP catalyst separately use 10 drops to 30ml resin. Go to www.aldax.com.au Tech Tips and you will find a colour chart for the opaque and transparent dyes to be used with polyester resin. You need to use very little as it is highly concentrated a match stick dipped in the dye and swirled in resin is all you need. All the best Stan Alderson
