Silver is a very unique effect pigments, Zhuang Cailv silver can be divided into floating and non-floating type, silver plating, the imitation silver plating, young silver, tin, silver flash, flash silver, crude flash silver, high silver flash strong flash of silver. It consists of a very smooth and very thin scaly structure, high hiding power of the small particle size, strong coloring, color and clarity, the integration density and white degrees in a surface coating can produce elegant, soft mirror the optical metallic effect.

Silver with a slurry, easily dispersed, hiding power, the centralized uniform particle size distribution, surface smooth, delicate, strong metallic effect and the flip-flop effect, and has the characteristics of heat-resistant acid resistance.

Silver can be divided into different according to the size of the particle size of 220 mesh, 300 mesh, 400 mesh, 600 mesh, 800 mesh, 1200 mesh and 1500 mesh for customers to choose. Widely used in coatings, inks, building materials, arts and crafts, printing, paper, home appliances, toys and other fields.

1/2-1 times the amount of paint used in the use of silver powder when first slow speed stirring into a slurry with a solvent after infiltrating a uniform dispersion, and then under stirring and gradually add deficits resins, solvents, and additives. Avoid the use of a ball mill or high-speed stirring to avoid damage to the aluminum foil shape.

Note that silver should be in a sealed condition to avoid the sun, the rain, and stored in a dry room (35 ° C or less) as soon as possible after use should be immediately and completely sealed to prevent volatilization of solvents and additives, in order to avoid the slurry dries causing black oxidation.

The aluminum paste major constituted by aluminum powder, solvents, and additives. Zhuang Cailv silver paste can be divided into two categories of leafing and non-leafing, leafing silver paste because of its low surface tension floating at the surface of the coated touch, but aluminum is easy from the film with a highly reflective chrome effect off the surface, causing recoating difficulties to be applied to the corrosion, roofing, tank and other occasions; coating completely wetted non-leafing Pastes can be evenly distributed in the entire film, and has a trend of sinking solid coating film stable, can also be re-coated with varnish, widely used in transportation, furniture, electronic products, coils and other occasions.

Aluminum paste is widely used in the automotive paint, motorcycle paint, bike paint, plastic paint, architectural coatings, inks, mobile phone casing and buttons, mechanical and electrical enclosures, electrical enclosures, metallic paint, and many other areas, but do not dissolve in water-based paint, silver is a solvent-based.

The use of aluminum paste method is to add the right amount of organic solvent to the Silver retarder agitation, excessive mixing will be the destruction of the surface of the silver paste coverings. Full immersion, dispersed, and should be used as soon as possible after opening and sealed.

Aluminum paste should not be exposure to rain, and should be stored in a dry room (35 degrees) storage time should not be too long, unpack use, should be used as soon as possible, such as can not be a one-time use finished, should immediately be completely sealed prevent aluminum paste, solvents, additives evaporate, leaving time for too long, before use detection.
