RODUCT DESCRIPTION
Coating Enhancing Nanopowder Pai-006 is the joint achievement researched by several scientific institutes. By adopting the modern nanotechnology, it becomes a high density particle with a narrow size distribution. Adding in other properties like high chemical stability, this nanopowder is developed into a brand new product specialized for anti-corrosive coating enhancement.

It can be seen from the Table 1 that after 1000 hours of salt fog exposure, all the coatings suffer from different degrees of damage and corrosion except the NC1+ND1 coating, which retains a perfect quality.

Figure 1 and Figure 2 show the enlarged SEM images (magnification x15000) of C1+D1 primer coating and NC1+ND1 primer coating. From the pictures, it could be easily noted that primer coating with the addition of Onmillion Pai-006 nanopowder is denser than that without the addition. It is because of this structural change that the anti-corrosive property of the coating is greatly improved.
DIRECTIONS The amount of addition to both primer coating and surface coating is 2-3%. In order to ensure a good dispersion of nanopowder in the coating, it is highly recommended to prepare a dispersed slurry which is then mixed with the coating for use.
