Devcraft GreenCast 160 Epoxy Clear Resin & Clear Epoxy Hardener - 1.42kg  (Clear)

Features: SR GreenCast 160 is a high clarity epoxy system with enhanced UV resistance. Designed for thick castings such as river tables, encapsulations, wood and resin combinations and decorative objects. The extremely low reactivity allows very deep castings to be made - thickness of up to 10cm at 20 C. GreenCast is bio-based and has a high content of carbon from plant origin. GreenCast 160 is compatible with a wide range of pigment pastes and powders. Cures at room temperature High clarity polymer, colourless and with good brightness. 40% bio-based carbon content. This product has been designed as a casting resin and not a coating resin. The open surface typically needs to be flattened and polished to achieve a perfectly flat, gloss finish. UV stability - this product will resist yellowing and is water resistant, however, it does not provide 100% UV protection and is not suitable for permanent outdoor exposure. UV protection can be improved by overcoating with protective urethane paint or UV resistant wax polish. Curing time - depends on the ambient temperature but around 48hrs to touch-dry but longer in thin castings. Allow at least 72 hours before demoulding or attempting to do any finishing work on the resin. The epoxy will take about 30 days to reach full hardness although this can be accelerated with a post cure of 24hrs @ 40 to 60 C Each kit contains a bottle of resin and a bottle of mega slow hardener which are mixed together at 100:42 parts by weight or 2 parts resin to 1 part hardener by volume. Coverage: 885 millilitres per 1 kg with 1 litre covering 1 square meter to 1mm of thickness Mixing ratio: 100:42 Popping bubbles: Mixing the epoxy resin and hardener will introduce bubbles into the liquid. In commercial environments the mixed resin is normally vacuum degassed to 'boil' out the bubbles. This requires a vacuum pot and a vacuum pump. Pouring the resin will also entrap and introduce air bubbles. The best tool for removing bubbles is a small propane torch. By holding the heat source approximately 300mm away from the surface and quickly sweeping across the surface the bubbles will start to pop. A heat gun or a hair drier can also be used to pop bubbles. It is a good idea to continue popping bubbles every 30 minutes until the epoxy has gelled.
