Aluminum silver paste can be divided into floating and non floating type two categories, the floatingtype silver paste and floating on the coating surface due to its low surface tension, has the extremely high reflective and chromium plating effect, but the aluminum sheet easily from the film surface off,causing heavy coated difficulties, application in anticorrosion, roofing, tank and other occasions; non floating type silver paste can be paint complete wetting, evenly distributed throughout the film, and has a tendency to sink, coating solid and stable, can also be re painted cover light, used in a large number of traffic tools, furniture, electronics, coil and so on various occasions. [1]

Aluminum silver paste is usually can be divided into imitation plating, silver, fine silver flash. Finesilver average particle diameter minimum, minimum brightness; silver flash average particle diameter of the largest, the highest brightness; imitation silver plating average particle diameter in the middleof fine silver and silver flash, brightness is between fine silver and silver flash intermediate.
