China aluminum paste
aluminum paste have excellent metallic effect , aluminum paste , have leafing , non leafing , electroplate , high whitness , high sparkle serious .
It is composed of very smooth and very thin scaly structure, small particle size of high covering power, strong coloring power, clear color, fusion density and white light in one, can make the surface coating produce high
In order to achieve satisfactory special effects, aluminum paste must be fully dispersed in the coating system, coating should be homogeneously state, not a fine grained, aluminum flake easily bend and broken in the process of coating production if after high speed stirring or other continuous rough machining, its geometric structure is easy to damage, so as to appear coarse, dark color, covering force is reduced, And metal drift and other undesirable phenomena should not be used high shear force dispersion means .
1. suggest disperse way : should be use suitable solvent mix , then aluminum paste with solvent 1：1 or 1：2 then fill aluminum paste , slowly make IT uniform (10-20minutes ). in then system add basic material , then fill aluminum paste 30minutes then mix .
2. The dilution selection of aluminum paste is mainly determined by the paint used in the formula. Non-floating aluminum silver paste can be widely used in polar and non-polar solvents, such as aliphatic or aromatic hydrocarbons, lipids (such as butyl acetate), ketones (such as methyl ethyl ketone, methyl isobutyl ketone), alcohols (such as ethanol).
3. Chlorine-containing solvent (halogenated...) Not suitable for any aluminum paste pigment. Chlorinated solvents release HCL, which reacts with fine aluminum pigments
4. Many commonly used paint bases such as oil-based varnish base, acrylic base, alkyd, cyclic urticate and water-based base can be applied to non-floating aluminum paste pigments. In general, any paint base or solvent is suitable as long as it is compatible with the solvent carrier of al/ag paste and does not cause chemical damage to al/ag paste. Special attention should be paid to the fact that aluminum is an active metal and the acid value of paint should be controlled below 7.
5.When a coating system containing aluminum paste needs to add metal drier, for non-floating aluminum silver paste,
Only dryers that do not react with fatty acids on the surface of aluminum scales can be used. Drilling, zirconium and manganese dryers are recommended
6.Adding proportion: aluminum paste adding proportion of colored primer 1%-4% aluminum paste adding proportion of pure silver primer ，Adding proportion: aluminum paste adding proportion of colored primer 1%-4% aluminum paste adding proportion of pure silver primer
Preservation method of aluminum and silver slurry: use a good cover aluminum slurry container to prevent air from entering volatile oil, solvent, so that the product blackened or oxidized, it is recommended to store in the warehouse of 15 degrees -40 degrees to avoid exposure to sunlight, rain or too much humidity, away from the fire, in handling and use, take gently, to maintain local ventilation. When agitating the product, the speed of the mixer should not be too fast to prevent the damage of the aluminum sheet and affect the quality of the product.
