GENERAL DESCRIPTION This specification covers a plastisol type sealer, capable of being applied directly over ELPO primed surfaces, and inten

3、ded for sealing body joints. It is used under exterior enamel painted surfaces. The sealer shall be a contrasting colour to ELPO primer. It shall be smooth, homogeneous, and free from lumps and unmixed particles. It shall be compatible with wet primer surface and GM Holden enamel paint systems. It s

4、hall cure in the primer surfacer oven into a tough, resilient seal. The sealer must be capable of being applied by extrusion gun or airless spray. It must also be capable of accepting up to 50% air by volume when used in conjunction with the Nordson Foam Mix System. The applied bead may be brushed w

5、here necessary and should be removable with a dry cloth. 2. DETAILED REQUIREMENTS 2.1 Odour The sealer must not be toxic or noxious. After curing it must be relatively non-odorous. 2.2 Stability The shelf life of the material shall be 90 days at a temperature not to exceed 35 C. Shelf life of materi

6、al commences upon receipt of the material at the assembly plant. Material at the end of this period must be capable of passing all the applicable requirements of this specification except viscosity which shall be a maximum of 60 seconds when tested as in clause 2.4. 2.3 Solids Content 93.0% by weigh

Test Method - Apply a bead of material 4.8 mm x 4.8 mm x 178 mm (3/16“ x 3/16“ x 7“) with a scraper to a 250 mm x 250 mm (10“ x 10“) primed panel. Set the test panel in the vertical position with the bead horizon

10、tal, air dry for 20 minutes. Bake the panel in the air dry position at 145 C 5 C for 30 minutes and measure the sag. Sag is the total width of the bead minus the width of the original bead. 2.6 Viscosity and Yield Stress (Sag) by Rheometer Method Release viscosity at 131 s-1to be 57-63 Poise and rel
