FORM : I:MaterialsEngineeringStandardForms MaterialSpecificationMatspec.doc 1. SCOPE This specification details the requirements of a high bake, non-paintable, fuel resistant, wel

3、d through sealer capable of being pumped at ambient temperatures. This material must have excellent adhesion to oily metal and resist wash-off through phosphate and E-coat. This expandable sealer is intended for use in the body shop to seal body joints against water, dust and air intrusion. The seal

4、er must exhibit very even and controlled expansion characteristics and must not accelerate corrosion of the metal substrate over which it is applied. The material must be a smooth and homogeneous mixture free of air, lumps, unmixed particles and foreign materials. It must be capable of being dispens

5、ed with standard production pumping equipment. Type 1 defines a non-expanding sealer (0% Expansion) Type 2 defines an expanding sealer with (65% Expansion) 2.

Sealer must exhibit cohesive failure after heat ageing. 4.2 Corrosion Resistance Prepare panel assembly by taking two 0.8mm x 300mm x 100mm plain s

15、teel panels (CRS), placing a 250mm x 3mm bead of sealer centrally on one of them and placing the second panel directly over the first. Spotweld the panels together by placing 5 spotwelds uniformly spaced along the centre line of the panels through the sealer bead. Panel assembly is then put through

16、production phosphate and ELPO paint system. Expose the panels to 1000h salt spray exposure as per ASTM B117. After completion of the corrosion cycle, remove test panels and immediately rinse with warm water. Drill out the spot welds and pry panels apart. Carefully remove sealer with scraper and exam

17、ine panel condition for rust below the sealer bead. Upon conclusion of test, there must be no rust beneath the sealer bead and the sealer must exhibit cohesive failure.
