[Video] Mixing Polyester Resin

Step 3 Mixing - No Fillers

Mixing without a filler or additive is actually quite easy. Simple measure off the amount needed and, when you're ready, add your MEASURED catalyst. Then mix throughly.

Here's a tip: Resin curing is an exothermic reaction - that is, the resin cures when it gets warm/hot. This heat comes from the aforementioned conditioners reacting with your catalyst. So, vigorous mixing is not necessarily recommended as the additional heat will reduce your pot time - this goes double for thickened resins.

Here's Another Tip: Pouring Resin from large 5 gallon jugs is a pain in the butt. Unless you know how! Those spout tops are positioned such that if you tip it on it's side with the top at the higher side, the resin will just barely reach that level. Then, roll the can to pour resin. See video for an example.
