I have gathered a few interesting molds from the Environmental Technologies mold catalog. These are re-useable, self releasing
polypropylene molds for use with Castin’Craft Clear Polyester resin. I am definitely conditioning them with a mold release.
All molds require mold release when casting with Clear Polyester Casting Resin. ETI recommend
Mold Release/Conditioner as a release agent and to clean, condition and extend the life of your molds.
This resin is very different that Envirotex Lite. To begin, opening the can requires a little planning. I punctured a few tiny holes so I can pour slowly. As always, measuring is the key to success. For Polyester Casting resin you add drops of catalyst to ounces of resin. Instructions and measurements are on the product.
You really need to read the instructions for this product.
Casting resin’s curing process is caused when heat is generated by the chemical reaction that takes place when catalyst is added to casting resin. Keep this in mind when reading through this bulletin and working with Castin’Craft Casting Resin.
I would also strongly advice you to read the Castin' Craft Idea book which is available free online.
This is what I will be embedding for my first project!
See you Monday!
Remember, due to the nature of casting resin, consistent results are obtained through attention to detail. Never place one of a kind objects in casting resin, because once in, it is almost impossible to remove. Always practice before doing your final piece. Start small and work up to larger items so you can become comfortable when working with casting resin.
