Castable daylight resin is specially formulated to provide high definition moulds. It will leave almost no ash when burnt and create gas evenly as the temperature is increased, avoiding any pressure build up within the casting. It will capture all the details with a very dry surface to provide the ideal finish to your investment mould.
Photocentric Castable Daylight polymers are water washable meaning that you do not require any chemicals to clean up your model. Simply run under the hot tap and place in a bowl of water and then leave to harden in sunlight for about 10mins.
Take a look out the all the Liquid Crystal daylight resins.

|2 °C/min||732||3 hrs|
