Rheology modifier RM 1965 is a significant additive in the field of coatings and formulations. Here is an introduction to it:

Function and Performance:

Effective Pigment Settling Control: RM 1965 is a broadly applicable rheology modifier that is highly effective in controlling the settling of pigments in solvent-based coatings and pigment concentrates. It develops a more shear-thinning rheological behavior, which means that under high shear forces (such as during application), the viscosity decreases to allow for easy application, but at rest or under low shear conditions, the viscosity is high enough to prevent pigment settling. This helps to maintain the homogeneity of the formulation and ensures consistent color and performance throughout the coating.

Prevention of Hard Sedimentation: It prevents the formation of hard pigment sedimentation at the bottom of the container. This is crucial for maintaining the quality and usability of the coating over time, as hard sedimentation can lead to issues such as uneven application, color variation, and reduced performance.

Application Areas: It can be used in all solvent-based applications where high pigment loads are involved, making it suitable for a wide range of coating systems, including industrial coatings, automotive coatings, and other specialty coatings.

Compatibility and Versatility: RM 1965 is compatible with various solvents and other components commonly used in coating formulations, allowing for easy incorporation into different systems without causing compatibility issues. This versatility makes it a valuable additive for formulators who need to adjust the rheology of their coatings while maintaining the overall performance and stability of the formulation.

In summary, rheology modifier RM 1965 is a powerful tool for formulators in the coatings industry, offering effective control of pigment settling, prevention of hard sedimentation, and compatibility with a wide range of formulations, thereby enhancing the quality and performance of solvent-based coatings.
