7.0 NOTES.
Note 1. South California Air Quality Management District Rule 1124; excluding water and exempt solvents.
Note 2. ASTM D 2369 may alternately be used to measure the VOC limit.
Note 3. Test panels. Obtain or prepare the required number of flat (3) 76 mm X 127 mm X 0.6 mm test coupons from any flat, cold-rolled, carbon steel sheet or plate. Abrade an entire face surface with 200-grit emory paper until the panel is uniform in appearance. Degrease the surface with clean lacquer thinner. Repeat as necessary to a uniform surface appearance. Use new Emory paper on each coupon. Prevent flash rusting by placing the prepared coupons in a oven set at 65oC (150oF), until use. Cool the coupons to room temperature before application of enamel in the following test procedures.
Note 4. Accelerated weathering. Prepare three steel test coupons as described in Note 3 above. Draw down a 5-cm (2.0 inch) wide film of enamel, using a 0.0030 inch gap clearance film applicator, onto two flat aluminum panels and air dry for 7 days, between 21-23oC and between 50-60% relative humidity. Measure the 60o specular gloss and 45o and 0o luminous directional reflectance of the coating. Subject the test panels to 168 hours of Xenon Arc weatherometer exposure, without water, in accordance with ASTM G 26. The test fails if more than one fails.
Note 5. Water Resistance. Prepare three steel test coupons as described in Note 3 above. Apply sufficient test enamel to an unprimed steel test panel to result in a uniform 1.0 +/- 0.2 mil dry film. Any method of film application may be used provided a smooth and uniform results. Permit the film to cure by air drying for 7 days between 21-23oC and between 50-60% relative humidity. Seal the edges of the paint film with melted paraffin wax. Submerged the test coupons horizontally under 2.54 cm (1.0 inch) of 23oC tap water for 24 hours, remove and sponge dry. Repeat this procedure for seven (7) cycles with no more than 15 minutes before re-immersion. The enamel fails if more than one specimen shows even slight visual indication of “whitening clouding”, softening, lifting, blistering, change in color, loss of adhesion or hardness. Hardness shall be test 24 hours after last immersion and shall be greater than 90% of a control panels hardness when tested in accordance with ASTM D 1474, Method A.
