PU, HASE and Inverse Emulsion Rheology Modifiers

Product Overview

 

TAFIGEL® rheology modifiers comprise a range of thickener types for water-based systems. TAFIGEL® PUR thickeners work via a HEUR-type mechanism, whilst TAFIGEL® AP thicken via an inverse emulsion or HASE mechanism. A whole spectrum of rheological characteristics is achievable with this range: from Newtonian to highly pseudoplastic. Our PU thickeners have a non-ionic structure, allowing them to thicken independent of pH whilst improving compatibility with other formulation ingredients. Viscosity is built (favoured over elasticity) which means low spatter and good pick-up. This makes them an excellent choice for paints, lacquers, emulsion plasters, adhesives, sealants, and printing inks.

An introduction to rheological additives for coatings

Rheology – from the Greek rheos - is the study of flow and is used to describe the deformation of a material under stress. The effects of rheology can be seen everywhere; compare oil, honey, and bitumen, all are liquids yet each flows very differently. Controlling rheology is crucial for the paint formulator to not only provide enhanced application properties but also to provide long term stability. In this technical article, we will discuss the fundamental principles of rheology, how this relates to coatings, and will take a closer look at materials that can be used to modify flow behaviour.
