(2) evaluation of defoaming and depression
In base coat, add defoamer and make its amount reach 1%, use the super automatic homogenizer that the turbine type blade is installed under 15～25 ℃, to carry out 10 minutes mixing, obtain coating with 2000rpm.In addition, except not adding defoamer, adopt method same as described above to obtain blank coating (not adding defoamer).Then, for these coating with JIS K5600-2-4:1999 (metal system specific gravity bottle: the proportion of the coating after the stirring of firm end after 10 minutes that be reference measurement hydrometer jar).Proportion is big more, shows that the intervention of bubble is few more, and defoaming is good.
In addition, { thick 0.5mm is cut into 20 * 30cm} and carries out degreasing, uses the applicator coating composition then, makes its wet-film thickness reach 250 μ m, observes film coated surface then, by following benchmark evaluation depression to glass plate with acetone/cloth.
