NOVELTY - The wind power class hand paste resin system comprises an epoxy compound component and degeneration hardener component in a weight ratio of 100:32-36. The an epoxy compound component comprises 74-94% bisphenol A epoxy resin, 0-10% heat resistant epoxy phenolic resin, 2-12% flexible epoxy resin, 3-15% reactive diluents, and 0-10% non-reactive diluents. The degeneration hardener component 58-78% cycloaliphatic amine, 0-20% amidoamines, 17-37% aliphatic amines, 0-10% cashew nut shell oil modified phenolic amine, 0.5-5% accelerator, 0-8% rheological additives, and 0-1% dye.    USE - Wind power class hand paste resin system for use in wind turbine blades and other large area composite materials.    ADVANTAGE - The wind power class hand paste resin system ensures excellent sag resistance and crystallization resistance, good environmental impact, and enhanced overall mechanical performance, toughness, heat resistance and water resistance to meet practical requirements of manufacturing and repairing.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing wind power class hand paste resin system, which involves:    (A) preparing epoxy resin component my mixing bisphenol A-type epoxy resin, flexible epoxy resin, and reactive diluent in a reactor at 60-70 degrees C for 2-4 hours to prepare an epoxy resin component;    (B) placed the formed epoxy resin component in a sealed container at room temperature;    (C) adding non-reactive diluent in the reactor with stirring for 2-4 hours to form alicyclic amine;    (D) adding 8-16% bisphenol A epoxy resin and 30-45% benzyl alcohol in another reactor with stirring for 1-2 hours to form homogeneous mixture;    (E) placing the formed mixture in another reactor with stirring at 45-60 degrees C for 1-2 hours;    (F) cooling the formed material in a sealable container at room temperature to obtain alicyclic amine;    (G) denaturing the prepared hardener component including synthetic alicyclic amine, aliphatic amine, accelerator and dye in a high speed mixer at room temperature; and    (H) mixing the formed mixture uniformly to form the wind power class hand paste resin system.
