Coatings Thickener Usage Guide:

How to Properly Select and Use Thickeners

Coatings thickeners are essential coating additives primarily used to regulate the rheological properties of coatings and improve application performance. Below, we provide a detailed overview of their specific functions and usage methods.

I. Main Functions of Coatings Thickeners

  1. Adjust Coating Viscosity:Thickeners effectively increase coating viscosity by forming a three-dimensional network structure. This not only makes the coating easier to apply but also ensures it adheres to the substrate at an appropriate thickness.

  2. Enhance Adhesion:By increasing coating viscosity, thickeners prolong the dwell time of the coating on vertical surfaces, allowing full contact with the substrate, thereby improving adhesion.

  3. Improve Coverage Performance:Optimal viscosity prevents rapid pigment settling, ensuring uniform pigment distribution and enhancing the coating’s hiding power, making it easier to cover surface defects on the substrate.

II. Correct Usage Methods

  1. Addition Steps

  • Thoroughly stir the coating first

  • Slowly add the thickener while maintaining stirring

  • Continue stirring until fully homogeneous

  1. Key Usage Points

  • It is recommended to add in batches for better viscosity control

  • If clumping occurs during addition, extend the stirring time

  • Adjust the dosage as needed to achieve the desired viscosity

III. Important Considerations

  1. Maintain continuous stirring during thickener addition to ensure uniform dispersion

  2. If viscosity is too high, add a small amount of water for adjustment

  3. Conduct small-scale tests prior to full application

  4. Pay attention to compatibility with different coating systems
