  1. I used CCR to make a casting and ended up with some bubbles (thought the surface was completely sealed but I must’ve missed a couple of spots). I’ve been doing research on fixing it and found suggestions to sand down past the bubbles, sand the whole surface and reapply a thin coat. Haven’t found anyone doing this with Entropy’s resins specifically, or CCR-like products. Mostly with resins meant for thin coatings (e.g.: ArtResin). I’m curious if anyone has tried anything like this or if anyone knows whether this method would not work with this product. If not, what's the best approach to fixing trapped bubbles? Should I use the super sap one instead of the ccr to apply a thin coat after sanding? Thanks,Steve
  2. Hi Rick, Thanks for your prompt reply! I am using the slow hardener, so that should be okay. The thing I'm not sure about is the amount I need to mix in order to fill the required volume. Is it a straightforward rectangular volume calculation same as if you're filling it with water or is there a different formula to use for the resin? Thanks!
  3. Hello, I’m getting ready to make some large castings using Entropy's Super Sap CCR. It’s my first time using their product. I plan to use a vacuum chamber to degas the mixture before pouring (I assume that’s required given the large volume I'm casting?) I just have a quick question about measuring the right (approximately) amount to mix. The casting is of rectangular pieces that I’ve framed. They’ll be of various sizes but I’ll use one as an example. 24″ x 19″ x 0.5″ (length x width x depth of resin I’m looking for). If I calculate the volume of water in a container that size and it comes out to be about a gallon (slightly under). Is this correct for resin as well or is there a different formula to use? Thanks!
