Basic properties of BES sodium salt

 

BES sodium salt has good water solubility, and its acid-base form does not chelate with certain metal ions, with a buffering range between 6.6-8.0. These characteristics make BES sodium salt widely applicable in chemical synthesis and applications.

 

The role of BES sodium salt in the synthesis of waterborne polyurethane coatings

 

Hydrophilic chain extender

 

BES sodium salt contains hydrophilic groups, and when combined with polymer materials, it can significantly enhance the hydrophilicity of the material. In the synthesis of waterborne polyurethane coatings, BES sodium salt acts as a hydrophilic chain extender, which helps to disperse and stabilize polyurethane molecular chains well in water.

 

Increase solid content

 

Compared to other types of hydrophilic chain extenders, BES sodium salt can prepare water-based polyurethane dispersions with high solid content. This not only improves the utilization rate of the coating, but also reduces the use of solvents, which meets the requirements.

 

Easy to control the preparation process

 

The use of BES sodium salt makes the preparation process of waterborne polyurethane coatings easier to control. By adjusting the dosage and reaction conditions of BES sodium salt, the performance of the coating can be accurately controlled to meet the application needs of different fields.

 

Performance advantages of BES sodium salt modified waterborne polyurethane coating
