The poor compatibility of PU color paste may lead to problems such as uneven coating surface, blistering, and cracking. The following are some methods to solve the problem of poor compatibility of PU colorants:
Pre-testing: Before large-area application, it is recommended to conduct a small-area color formula test to ensure that the PU color paste has good compatibility with other ingredients.
Adjust the formula: Depending on the actual situation, you can try to adjust the formula of the PU color paste, such as appropriately reducing or increasing the dosage of other ingredients to improve the compatibility of the color paste with other materials.
Adding additives: Some special compatibilizers or additives can be added to help improve the compatibility of PU color paste with other ingredients. These additives improve the stability and uniformity of coatings.
Stir fully: When using PU color paste, make sure to stir and mix thoroughly to ensure that the various ingredients are fully mixed and evenly mixed to reduce the occurrence of compatibility problems.
Choose the right substrate: Before painting, choosing the right substrate is also an important step. Different base materials have an impact on the compatibility of PU color paste. Choosing the appropriate base material can reduce the occurrence of compatibility problems.
Professional consultation: If you encounter serious compatibility problems that cannot be solved, it is recommended to seek help and advice from coating experts or suppliers, who may provide targeted solutions.
