Review on Liquid Urethane Rigid Pour Density Tapes, Adhesives & Sealants by Eduardo Reyes

I have a project where I need a lot and I mean a lot of foam skulls. I decided to try my hand at making a simple skull silicone mold and use this urethane to make my skulls. SUPER ECONOMICAL this way. Not too big a learning curve either! No mold separator required, just mix, pour, shake a little and wait 15-30 minutes to eject the mold. Works great! Update - finally through the first set of bottles I ordered. My skulls required 3-5 mixed ounces of product (1.5-2.5 ounces for each A and B) and I was able to make a total of 29 skulls and 2 small jaws. This was my first time making molds and working with two component foam. Given the learning curve, I expect to get 35-40 skulls out of the next set of bottles as I have a better understanding of how to reduce waste and how much product to use and in what form. I also found that leaving the foam in the mold overnight resulted in more detail, less shrinkage, and better surface coverage. Also a little easier to disassemble.
