2、FIRM THE DOCUMENT ISSUE DATE IS STILL VALID.FORM : I:LABRTORYFORMSTDMATSPEC.DOC1. GENERAL DESCRIPTION:This specification covers a plastisol type of sealer for use in sealing body jointsunder exposed acrylic lacquer paint finish surfaces. The sealer must adhere tophosphated and primed steel surfaces.
3、The as-received material shall be easy to handle without exhibiting a dry crumblyappearance. On working with the hands the material shall become tacky withoutbeing excessively so. Little or no material shall remain on the hands after 30seconds of kneading.On baking, the sealer will fuse into a tough
4、 resilient crack resistant materialwhich is completely compatible with GMHA paint systems.2. DETAILED REQUIREMENTS:2.1 Odour -The sealer must not be toxic or noxious. After curing, it must be relativelynon-odorous.2.2 Stability -2.2.1 Elevated Temperature Stability - As shipped, the adhesivemust be
5、capable of withstanding a temperature of 54 C (130F) for 72 hours and still conform to the requirements of thisspecification.2.2.2 Storage Stability- The shelf life of the material shall be 90 daysat a temperature not to exceed 35 C (95 F). Shelf life of thematerial commences upon receipt of materia
6、l from themanufacturer.2.3 Packaging -The material must be packed in such a manner that no difficulty shall beencountered in removing it from the container.A.C.N. 006 893 232Holden LimitedEngineering DepartmentMATERIAL SPECIFICATIONNUMBERSHEETRELEASEREVISION:HN 13772 of 5July, 1974April, 1992NAME: P
