    摘要: The present invention provides a curable resin composition having good curability and storage stability, which provides a cured film having excellent weather resistance, acid resistance and mar resistance. The curable resin composition comprises:(a) 20 to 80% by weight of a polycarboxylic acid having an acid value of 25 to 300 mg KOH/g based on solid and a number average molecular weight of 500 to 20000; and(b) 20 to 80% by weight of a polyepoxide having an epoxy equivalent of 100 to 800 and a number average molecular weight of 500 to 20000, prepared by copolymerizing: (1) 10 to 60% by weight of a long-chain epoxy monomer; and (2) 40 to 90% by weight of an ethylenically unsaturated monomer having no epoxy group. The present invention also provides a process for forming a cured film using the resin composition.

    摘要: Provided is an air heat exchanger capable of preventing an increase in ventilation resistance and a decrease in heat exchange efficiency due to condensation water generated on surfaces of heat transfer fins, without increasing thermal resistance of flat tubes and the heat transfer fins, and preventing scattering of water droplets downwind from the heat transfer fins. In the air heat exchanger including a plurality of flat tubes 2 and heat transfer fins 5 provided between the flat tubes 2 and on which air is blown, the flat tubes 2 include water draining grooves 4 on side surfaces on which the heat transfer fins 5 are provided and the heat transfer fins 5 include water guiding grooves 6 communicating with the water draining grooves 4. At least a groove wall 40 on the upwind side of an air blowing direction 10 among groove walls forming the water guiding grooves 6 is provided from a position of the upwind side from the water draining grooves 4 to the water draining grooves 4. The water guiding grooves 6 extend toward the water draining grooves 4 along the groove wall 40 on the upwind side and an area of a cross section perpendicular to an extension direction decreases toward the water draining grooves 4.
