The material temperature must be 18 - 25°C. The resin component (A) must be shaked well 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 12 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 for...
