<p><P>PROBLEM TO BE SOLVED: To provide a thermoplastic resin sol composition which can be used as a sealing material, an undercoat material or the like without causing abnormal swelling when it is heated and cured after being applied and thereby without necessitating the number of steps such as a repairing step, even in the case that the composition is allowed to stand for ten days under such a wet condition that RH is 80% at 30°C. <P>SOLUTION: In the case that 100-110 pts.wt plasticizer, 7-19 pts.wt block urethane prepolymer containing an aromatic isocyanate as a component, 2.3-5.4 pts.wt water soluble polyamide-amine having a melting point in a range of 40-120°C, and 140-160 pts.wt inorganic filler are contained based on 100 pts.wt of a thermoplastic resin, the viscosity of a thermoplastic resin sol becomes in a proper range, the hardness in a dried state is enhanced, and the surface film is sufficiently formed, thereby, the possibility of generation of swelling when the sol is heated and cured is completely avoided. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
