The material temperature must be 18 - 25°C. The resin component must be stirred thoroughly before use. Both components must be under vacuum for several minutes before mixing in right mixing ratio and poured into preheated moulds (70°C). After complete filling of the moulds, vacuum is switched off and moulds are placed in an oven at 70°C for curing until demoulding. Minimum shelf life is 6 month under room condition (18 - 25°C), when stored in original un-opened containers. After prolonged storage at low temperature, crystallisation of components may occur. This is easily removed by warming up...
