What to do if the metallic feeling and white brightness of water-based aluminum paste are poor
With the coating industry’s increasing demand for water-based aluminum
pastes, the market’s requirements for water-based aluminum pastes are
also rising. Especially the metallicity, white brightness, hiding power
and stability are the most important factors considered by customers.
Several difficult factors in the promotion process. So, what should I do
if the metallic feeling and white brightness of the water-based
aluminum paste are poor?
The water-based aluminum paste itself will affect the metallic feel,
white brightness, hiding power and stability, which are mainly
manifested in:
1. The metal feel is not strong
There are several main reasons for this. On the one hand, the coating
process of the water-based aluminum paste itself causes the metal feel
of the water-based aluminum paste to become weak; the resin system
selected by the customer is incompatible with the water-based aluminum
paste, resulting in poor alignment. This will affect the final metallic
feel; there is also a defect in the customer's own formula design that
makes the metallic feel unable to come out;
2. The white brightness is not enough
Because the water-based aluminum paste itself is divided into two
types, the green phase and the white phase, if you need a good whiteness
effect, you need to find a white-phase water-based aluminum paste. Of
course, the quality of the arrangement will also affect the effect of
the final water-based aluminum paste. In addition, some customers who
have high requirements for whiteness can also try to use fine silver;
3. Poor stability
The most prominent phenomenon is flatulence, which is also the most
common problem encountered at this stage. On the one hand, the main
cause of flatulence is that the coating layer of the water-based
aluminum paste is not dense enough, or the temperature of the storage
environment is caused. On the other hand, in the process of formula
design, other raw materials added are incompatible with water-based
aluminum paste, which is also the main factor causing flatulence
problems.
The above content is to analyze the reasons for the poor effect of water-based aluminum paste.
The water-based aluminum paste is easy to disperse, good hiding power,
concentrated and uniform particle size distribution, smooth and delicate
surface, pure and bright color, strong metallic feeling and white
brightness, and has good oxidation resistance and abrasion resistance.
Heat resistance to acid and alkali. Therefore, it is used in products
that require high environmental protection, such as clothing, paper
printing, wallpaper, plastics and other industries.
