Zusammenfassung: | PURPOSE:To prevent leakage of air by holding airtightness during low compres sion. CONSTITUTION:An air-conditioning member for a vehicle having a seal margin 7 to which a sealant 11 is adhered by hot melt is mounted on the back of the panel of a vehicle by means of a mounting means, and the seal margin 7 is of seal structure wherein the sealant 11 is compressed to the back of the panel for sealing. The sealant 11 is formed of hot melt type thermoplastic resin which has a melt temperature of 160-200 deg.C, a viscosity value of 100000-25000cps by a B-type viscometer, and independent air bubbles foamed with an expansion rate of 2.5-3.5 times. |
