Epocast® 52 A Resin 100 2 Epocast® 52 B Hardener 41 1 Mix both components thoroughly for several minutes until a homogeneous mixture is obtained. Material temperatures should be above 18°C (65°F) when mixing. Mix carefully to minimize air entrapment. Mix only the amount of material that can be used within 40 minutes. Heat buildup during or after mixing is normal. Allowing quantities greater than 250 grams to gel can produce excessive exotherm that may cause product decomposition and generate toxic fumes. Spreading material to a shallow tray (reducing mass/surface ratio) will minimize heat buildup and extend gel time. Mixing smaller quantities will minimize the heat buildup.
