The paint shall be returned to a smooth and homogeneous consistency, which is free from; gel structures, persistent foam or air bubbles using only hand mixing. 2.3 Shelf Life When stored in a three-quarters filled can for a period of thirty days, the paint shall be in a homogeneous state with no skinning, curdling, hard settling or caking that cannot be readily remixed. 2.4 Heat Aged Stability White Yellow Degree of Settling, minimum, ASTM D A 500 ml (1 pint) paint can is filled with a well mixed sample. The can is capped and allowed to set undisturbed at standard conditions for 14 days. The settling is then determined as specified in ASTM D869.

The paint shall produce a film which is smooth, unifonn, and free from: grit, undispersed particles, craters, pinholes and cracking Dry Opacity minimum White Yellow On a black-white Leneta chart, Form 2C-Opacity, draw down a uniform 250mm(+/-lO mm) thick wet film of paint covering both the black and white portions of the chart. Measure the wet film thickness with an appropriate gauge. Dry for 24 hours at standard conditions. Use a BYK-Gardner Color-Guide Spectrophotometer to measure the opacity according to the manufacturer s instructions. Calibrate the spectrophotometer according to the manufacturer s instructions using; 2 Observer/Illuminant C measurement conditions, and the (Y, x, y) color system Yellowness Index maximum White Yellow 8 - Draw down a 330 mm thick wet film of the white paint on two 75x1 50 mm chromate treated aluminum panels (i.e.: Q Panel Co., type AL). Dry for 24 hours at standard conditions. Save one panel for the Accelerated Weathering test (section 2.20). Using a BYK-Gardner Color-Guide Spectrophotometer, follow the manufacturer s instructions, and measure the Yellowness Index of the white paint film using the ASTM E3 13 mode Daylight Luminous Reflectance White Yellow >= Using the draw down panels prepared in section 2.16, measure the reflectance of the white and yellow paint films using the BYK-Gardner Color-Guide Spectrophotometer. Follow the manufacturer s instructions to obtain the Reflectance or Y value Yellow Color Draw down the yellow paint on two chromate treated aluminum panels as described in section One panel should be used for the Accelerated Weathering test (section 2.21). Retain the other yellow panel as a control and for the Reflectance test.
