Best practices when selecting rheological additives are discussed in this article. The article explains that properly prepared technical materials are the basis for a quick and efficient start of tests and drawing conclusions based on repeated case studies in specific paint manufacturer formulations.
As a stabilizer and secondary rheology modifier, colloidal MCC provided minimum viscosity to waterborne coating systems at low use level while significantly improving in-can shelf stability and color-tinting ability.
Four new fumed silicas from the AEROSIL® family are much easier to disperse. With these additives, formulators can omit the grinding step when incorporating them into paints or coatings.
These diamide rheology modifiers allow proper activation over a wide range of application temperatures to allow formulators robust and predictable processing under real-life conditions.
Elementis' THIXATROL PM 8058 provides formulation flexibility and higher performance than traditional thickeners for industrial coatings that contain aromatic solvents (e.g. Xylene) and polar solvents like alcohols (e.g. n-Butanol, Benzyl Alcohol).
Discover more about Elementis' next-generation rheology modifiers that prevent sagging and allow for thicker application layers in protective coatings.
The article also addresses a specific limitation (tint viscosity retention) that occurs with NISATs, and how next generation tint viscosity stabilizers help alleviate this concern.
Additives are used in small quantities and can have the highest per unit cost of coatings raw materials. They facilitate production, or improve certain properties of the wet coating or the final film. Learn about rheology modifiers and suspension agents in Part 1 of this four-part series.
