Review on 🧪 Density of Rigid Pour Liquid Urethane by Justin Early

The first test with it was 20ml (10ml A + 10ml B) at 68 degrees. The result was a nice, dense foam that slightly overflowed the 8 ounce (237 ml) plastic food container. No release agent was used and it popped out easily after eight hours. After an additional 48 hours, the foam was placed back into the food container mold and almost imperceptible shrinkage occurred.
