Rheology modifier RM 1900 is a remarkable additive with several notable characteristics and applications:

Product Description:

RM 1900 is a micronized thickening agent, which is a modified hydrogenated castor oil in the form of a white, microfine powder.

Function and Performance:

Superior Sag Resistance: It provides excellent sag resistance in non-aqueous formulations, which is crucial for coatings and other applications where the material needs to maintain its shape and integrity even when applied on vertical or inclined surfaces.

Temperature Stability: It offers higher temperature stability, allowing it to perform well in formulations that may be exposed to elevated temperatures during processing or in certain end-use environments.

Strong Thixotropic Effects: In solvent-based coatings, RM 1900 produces very strong thixotropic effects. This means that the material has the ability to change its viscosity under different shear conditions. When at rest, it has a high viscosity to prevent sagging and settling, but when subjected to shear forces (such as during application), its viscosity decreases, making it easier to apply and spread.

Compatibility and Versatility:

The rheology modifier is suitable for both solvent-based and solvent-free systems. It can be used in a variety of applications such as epoxy resin paints, plastisols, caulking compounds, putties, and knifing fillers, making it a versatile additive for different formulations in the coatings, adhesives, and sealants industries.

Solvent Dependency: The thixotropic behavior of RM 1900 is influenced by the type of solvent used in the formulation. Solvents mainly consisting of mineral spirits and aromatics are more suitable, while a combination with esters, ketones, and alcohols is possible up to certain limits.

In summary, rheology modifier RM 1900 is a valuable additive that offers excellent sag resistance, temperature stability, and strong thixotropic effects, making it suitable for a wide range of non-aqueous formulations in various industries.
