Review: My new favorite - Great product, cure time is 10 mins with a 2 minute work time. Comes out white. Product is lighter than epoxy but just as hard.
Review: Good quality Fast results - Mixing these on a 1:1 ratio was simple and the pumps in the kit made dispensing the resin simpler than pouring. I would pump each part (A&B) into a separate cup and then pour both into a 3rd cup (I use Dixie cups). I did it this way so I could verify equal amounts of A and B parts. I found that if I was off a little with amounts, that it still cured quickly (10-12 minutes) and I was demolding them by 15 minutes. This was my first time using urethane resin and you have to stir quickly and use immediately. If you are pouring a number of detailed smaller molds, plan your time to do it quickly, otherwise the resin will begin to cure while pouring and you’ll have a small mess. I like the fact that I have a piece ready to paint or finish within 15 minutes. Good product and while I had a few bubbles, I always have a butane torch to eliminate. Thus the finished products all came out great.

### ⭐⭐⭐⭐⭐ Great product. Cures quickly just like it says.
*by A***R on July 23, 2025*

This seems like a good resin. Cures really fast. I used a chrome nail powder on a small shiny silicone mold then filled it w this and they came out so pretty. Says cures in 10 mins but really 20 mins for mine. Prob because I added the powder to the mold. The little cap inside stuck to the bottle so I had a hard time getting it off, but other than that, it worked well.
