Two weighed 3 by 6 inch 2024 Alclad aluminum panelsshall be coated to the scribed line (see 4.6) and reweighed to obtain the weight of appliedcompound. The panels shall be s

44、upported in an upright position with the uncoated end downwardand shall be heated for 7 days in an oven at a temperature of 180 5 F. After cooling, the panelsshall be reweighed and the average loss in weight calculated. The panels shall show no flow overthe inscribed line and no loss of adhesion or

A coated panel which has been subjected to the resistance to drying andaging tests shall be immersed for 24 hours in ethyl acetate or other cleaning materialrecommended by the manufacturer for removal of the aged coating. The panel shall then beexamined

46、 for completeness of removal. The compound shall either be completely dissolved orloosened from the metal to leave a clean surface. There shall be no corrosion apparent on themetal (see 3.4.6).4.7.6 Water solubility . Two weighed 3 by 6 inch 2024 Alclad aluminum panels shall be coatedwith compound a

47、nd reweighed after drying to constant weight at a temperature of 150 5 F .
