Water aluminum silver for silver flaky powder, covering power extremely good, has the floatation, light opaque, the ultraviolet ray has the reflection ability, to the light of the sun's heat energy has the thermolysis, weather resistance is good, has excellent corrosion resistance and water resistance properties, it is the most widely used metal pigment. Because aluminium easy flying diffusion, the use of very inconvenient, will usually be aluminum silver paste and solvent oil is made with aluminum slip. Aluminum slip for paste, generally including aluminium powder 65%.
Silvery white scaly powder. Relative density 2.55. Melting point 685 ℃. Boiling point 2065 ℃. With fatty acids adsorption in the aluminum surface, the aluminium easy floating in the liquid. Flaky of aluminium powder particles, the tablet diameter and thickness ratio of about 100:1, and aluminum powder dispersed in the carrier has the characteristics of parallel with low material, many particle coupling, size particles fill each other form a continuous metal film, reflective external light, has the extremely good covering power. Aluminium formation of continuous metal film in the carrier membrane in a multi-level parallel arrangement, cutting off the wool stoma of film former, thus playing a good shielding effect. To ultraviolet light, infrared and visible light has reflection ability, to the light of the sun has thermolysis. Water aluminum silver aluminium powder pigment has the very good "contrast effect" characteristics. Good weather resistance. Soluble in acid or alkali, reaction with acid effect can produce hydrogen.
