Kneadatite, also known as Green Stuff is an 2-part expoxy putty presented as a ribbon in a hard plastic case. This case helps prevent the product from going off. Typically doubling the shelf life.When mixed evenly together the constituent parts (yellow and blue) will form a malleable and sculptable material. Simply cut horisontally across the ribbon and mix until a smooth green colour. Sculpt using tools for the desired finish. Over a period of 12-72 hours this will cure and harden. Once cured this can be used for the purpose of making a mould to cast or painted over like any plastic, metal or resin miniature.Additionally you can:Add more yellow (70/30) and the curing time will increase meaning you have an extended work time and softer media. Great for extra details.Add more blue (30/70) will result in a harder material that cures faster. Ideal for gap filling where detail is largely irrelevant.Please note: Green Stuff contains 3, 6-diazaoctanethylenediamin, which may produce an allergic reaction. A datachseet can be provided up requent.
