S3. disperse：HEXIOM3000, Opel enlightening 995, Thixol 53L, AMP-95, dipropylene are existed
Oily contracting is dispersed under the rotating speed of 1000rad/min, Tego760W, TS 6200 and transparent powder is sequentially added, keeps rotating speed to be dispersed to
Grain fineness is≤50 μm, adds oxidation aluminium paste, AMP-95, the LXE bactericide and water of ROHM AND HAAS, and is uniformly dispersed, and obtains water
Property one-component coating.
Above-described embodiment is shown in Table 1, table 2 with traditional based white primer the performance test results contrast：
Table 1：Embodiment 1-5 and traditional based white primer the performance test results
Table 2：Embodiment 6-10 and traditional based white primer the performance test results
By above-mentioned data, it can be seen that system of the present invention is higher than conventional based white primer hardness, and richness is good, slump resistance
By force, chemically-resistant is excellent, and combination property is completely better than common white primer performance.
