How To Choose Wax Emulsion For Waterborne Polyurethane System

In waterborne polyurethane system, multiple factors need to be considered when selecting wax emulsion to ensure that the wax emulsion is well compatible with the waterborne polyurethane system and achieves the expected performance effect. Here are some suggestions on how to choose wax emulsion:

1. Understand the needs of waterborne polyurethane system
First, it is necessary to clarify the specific application needs and performance requirements of the waterborne polyurethane system. For example, is it used in coatings, adhesives or other fields? What properties need to be improved, such as temperature resistance, wear resistance, gloss, etc.? These needs will directly affect the selection of wax emulsion.

2. Consider the compatibility of wax emulsion
Wax emulsion should be compatible with other components in the waterborne polyurethane system to avoid undesirable phenomena such as stratification and demulsification. Therefore, when selecting wax emulsion, compatibility testing is required to ensure its good compatibility with the waterborne polyurethane system.

3. Choose the right type of wax emulsion
Choose the right type of wax emulsion according to the specific needs of the waterborne polyurethane system. Common types of wax emulsions include non-ionic, anionic and cationic. Different types of wax emulsions have different performance characteristics. For example, non-ionic wax emulsions usually have better stability and compatibility; anionic wax emulsions may have better wettability and dispersibility. Therefore, it is necessary to weigh them according to actual needs when choosing.

4. Pay attention to the performance indicators of wax emulsions
When choosing wax emulsions, you also need to pay attention to their performance indicators, such as solid content, pH value, viscosity, density, etc. These indicators will directly affect the use effect of wax emulsions in waterborne polyurethane systems. For example, wax emulsions with high solid content may have better filling and wear resistance; while wax emulsions with moderate viscosity may be easier to mix evenly with waterborne polyurethane systems.

When selecting wax emulsion in waterborne polyurethane system, multiple factors need to be considered comprehensively, including application requirements, compatibility, type, performance index, source and price. Through reasonable selection and matching, the role of wax emulsion in waterborne polyurethane system can be fully utilized to improve the overall performance and quality of the product.
