Wilsor crystal clear polyester casting resin is ideal for smaller projects where shrinkage is not an issue. For example for casting insects, flowers or other small objects. The crystal clear polyester resin consists of two components (ratio 3:1) and the b-component is an MEK hardener.


Provide a mold into which the resin can be poured. The mold should be smooth, self-releasing and made of plastic to prevent sticking. Crystal clear casting resin does not adhere to Teflon, polyethylene and polypropylene (disposable cups). Mix 1% of the MEK hardener with the resin and stir well.

While the resin is still liquid, you can place insects, leaves or other small objects in it. Make sure there are no air bubbles in it.

Remove the object from the mold after curing. The side where the resin cures in contact with the air, the resin remains a little dull and sticky. Sanding and then working with Colad One step Ready creates a clear smooth coat.
