Coating on Plates
All test plates were washed with a mixture of water and detergents before
coating for tests. Paints were coated on glass sheets and PVC plates for glossiness and wet scrub tests using a Baker industrial film applicator (made by
TQC Co., Netherlands) to achieve 120 micron thickness for wet paint samples
(according to the ASTM D 82353-FMTS standard test method). Finally, all
paint films were dried at 25
C for one week under 5010% of relative
humidity (measured by a hygrograph instrument in a clean room). This dry
time is the same as the dry time of outdoor paints.
