2、ONDED ESB-M5G28-A ESB-M5G28-B1. SCOPE:The material defined by this specification is a filled asphaltic masticwith a polyethylene film on one side, and a pressure sensitive adhesiveon the other side, protected by a release paper which is removed prior toinstallation of the mastic part.2. APPLICATION:

3、This specification was released originally for material used as adeadener on 1976 Granada/ Monarch cowl side panels, dash panels, packagetrays and package tray strainers. It must be applied after paint ovensand limited to components not normally subjected to repeated impacts suchas doors, hoods, and

4、 trunk lids.3. REQUIREMENTS:Based on the mastic without the release paper.3.1 CONDITIONINGAll test values indicated herein are based on material conditionedin a controlled atmosphere of 23 +/- 2 C and 50 +/- 5% relativehumidity for 24 h prior to testing and tested under the samecontrolled conditions
