A mixed solvent comprises sec-octyl acetate and a co-solvent. A coil coating composition, based on the weight of the composition, comprises: (1) 1 - 50 weight % of the solvent; (2) 10 - 70 weight % of a resin as main body; (3) 1 - 40 weight % of titania; (4) 0.1 - 1 weight % of fumed silica. A method for preparing coil material comprises applying the coating composition to the surface of a coil substrate. The coil coating composition obtained by using the mixed solvent of the present invention has the following advantages, that is, having good fluidity, high solid content and high stability, being free of benzene toxicity, and the paint film formed thereby being clear and transparent and having good levelling properties. |
