One component, completely transparent resins which cure by UV light. (Requires a UV lamp to cure, separate product) - https://daliartmarket.co.uk/products/pentart-uv-lamp) Depending on the thickness of the layer, you need to use the UV light for 20 seconds for thin layers and 2 minutes for thicker (maximum 3 mm at once) layers to cure the resin. Apply the hard resin on top of projects in a thin layer as a varnish or cast small 3D forms using small silicon moulds with both of them. Colour with the Media Inks, make sure that the light can get through the material. If you add non-transparent elements to your creation, apply more layers and cure each layer thoroughly. The Hard resin cures very stiff and durable, the Soft cures flexible and has a rubbery like softness.
