It should be crystal clear and free of striations before pouring. Once measured in the proper 2:1 ratio, stir until well combined. We don't recommend using this epoxy under. If you're making a clear casting, we recommend doing thinner layers to prevent yellowing. For small castings this can be used up to 3", for larger castings like tables, we recommend pouring between 1" and 1.5" at a time. Larger slabs should be poured thinner than smaller castings to minimize exotherm. The maximum casting thickness can vary depending on a number of factors including ambient temp, material temp, volume, project dimensions, etc. Working with material above 75☏ and depending on volume, the River resin may set too quickly and exotherm (become too hot) which could cause it to yellow, distort, shrink or crack. When warm, it’s thinner and will set much faster.
When cool, it’s thicker and will set slower. Epoxy is a temperature-sensitive material. Keeping the work area cool by adding a fan can help reduce the risk of epoxy overheating.įor best results, all materials and working conditions should be at a constant temperature. Pouring too much epoxy into a large area can result in shrinking, yellowing, or cracking. Take into consideration the volume of epoxy you pour into a void. It is a high-performance, highly viscous, epoxy resin with a cure time between 12-36 hours, depending on the volume and thickness poured. You will receive (2) gallons of resin and (1) gallon of hardener.Ĭures to a crystal clear appearance and can be tinted with powdered or liquid pigments. PLEASE NOTE: This is an advanced 2:1 deep pour epoxy resin.
