Very clear, and hardly any bubbles. I initially bought the slow cure hardener, but exchanged it for the "fast" because until I visited the manufacturer's website I did not have the data. Slow is very slow! This product will not disappoint.

I have been using CCR and CCF hardener for 5 years now. This is the second and last time that I've had a problem with the hardener. The first time all of my pours, which were clear when they went in the molds, turned milky and opaque. My problem this time was drying time. I measured my epoxy and hardener with a scale and mixed per the directions. It took almost three days before I could remove from the molds. Thinking I may have made a mistake measuring I mixed another batch and poured it into the molds. Exactly the same result. Three days to dry enough to remove from my molds. I can't tolerate issues like this when I am trying to produce items to fill orders and meet deadlines.
