Quick Answer
EcoPoxy EcoPoxy FlowCast SR Slow Cure Epoxy mix ratio: 2:1 by volume, 2:0.86 by weight
Max pour depth: 2.0" · Full cure: 96h · Ideal temp: 72°F
⚠️ Exothermic Risk — The weight ratio (2:0.86) is NOT 1:1. Resin and hardener have different densities. Using a 1:1 scale ratio will result in incorrect curing. Always mix by weight using the ratio above.
Bio-based slow cure deep pour epoxy with extended working time for complex river table projects. Made from renewable plant-based materials with low odor and zero VOC. The slow cure schedule allows more time for bubble removal and manipulation. Produces a crystal-clear, bubble-free finish.
