Analysis reasons for lack of metallic effects of aluminum paste
Analysis reasons for lack of metallic effects of aluminum paste
Why does other company’s paint have excellent metallic effects by adding aluminum silver paste, But your paint always didn’t have enough metallic appearance?
Someone only see that the metallic effects not enough, and they continue to increase the dosage of aluminum silver paste and regardless of the reason. but the final result is often not very well. To clarify this issue, we need to consider the following aspects.
1.Type of aluminum silver paste: water-based or solvent-based?
Firstly, we need to know that there must be some differences between water-based aluminum silver paste and solvent grades. It is certainly difficult to achieve the effect of solvent-based aluminum paste using water-based one . At this point, blindly increasing the dosage of aluminum silver paste has little effect.
Usually, when using aluminum silver paste, different industries will have different addition ratios. When the addition ratio reaches its maximum, continuing to add aluminum silver paste not only can’t enhance the metallic effects, but also it will weak the resin lightness and may rise cluster, further influence the final effect.
2.The distribution of water-based aluminum silver paste
The metal effects of water-based aluminum silver paste is closely related to its arrangement and distribution. It can be said that the arrangement and distribution of silver paste is the main reason affecting the quality of water-based aluminum paste.
A large part of the reason is that there are problems with the arrangement of aluminum silver paste when the expected metallic effects cannot be achieved. Generally, there should be no problem with metal effects if the aluminium paste can be arranged in parallel in the resin system. But if the resin has an impact on the arrangement of the silver paste, it will lead metallic effects weak.
3. Formula of water-based aluminum silver paste
The same silver paste can be work very well in someone's company, with a strong metallic effects. However, if your effects is not very well. It is possible that the formula has an impact on the arrangement of the silver paste. Of course, it may also the silver paste itself lacks metallic effects.
Just like water-based aluminum silver paste, each silver paste formula is different, so the metallic effects is also different. If your formula and resin are fine, you can try to change another aluminum silver paste for testing.
Correct approach
So when the metal effects is not good enough, the correct approach should be to replace several grades for testing, or adjust the formula proportion.
