How To Choose Anti-settling Thixotropic Agent For Coating System?

The selection of wax powder for anti-settling thixotropic coating involves multiple factors. Here are some suggestions to help you make the right choice:

Understand the types and characteristics of wax powder: Different wax powders have different thixotropy and anti-settling effects. For example, organic wax powder forms a three-dimensional network structure under shear force, which gives the coating thixotropy. Polyamide wax powder has a special hydrogen bond structure that can prevent pigment sedimentation. Therefore, when choosing wax powder, it is necessary to determine it according to the characteristics and usage requirements of the coating.

Consider the particle size and specific surface area of ​​wax powder: wax powder with small particle size and large specific surface area is more likely to interact with other ingredients in the coating to form a stable system. Such wax powder usually has better anti-settling effect and thixotropy.

Evaluate the stability of wax powder: high-quality wax powder should have a high degree of stability and be able to maintain its performance unchanged during the storage and use of the coating. Wax powder with poor stability may cause the coating to have problems such as sedimentation and stratification during use.

Understand the compatibility of wax powder with other ingredients: When choosing wax powder, you need to consider its compatibility with other ingredients in the paint (such as pigments, resins, etc.). Make sure that the wax powder can be fully mixed with other ingredients to form a uniform and stable coating system.

Refer to actual application cases and performance data: When choosing wax powder, you can refer to relevant actual application cases and performance data to understand its performance in different coating systems. These data can provide you with valuable reference information to help you make a more informed choice.

In summary, choosing wax powder for anti-settling and thixotropic coatings requires comprehensive consideration of factors such as the type, characteristics, particle size, specific surface area, stability, and compatibility with other ingredients of the wax powder. By carefully evaluating and comparing the advantages and disadvantages of different wax powders, you can choose the most suitable anti-settling and thixotropic wax powder for your coating.
