Applying coatings onto basepaper surfaces requires optimum flow properties, usually achieved with low solids and viscosity. However, high solids and viscosity are needed to obtain a uniform coating layer and good printability. Finding a balance between coating application and printability requires an understanding of surface chemistry in coating formulation and rheology.
Commonly referred to as thickeners or viscosifiers, rheology modifiers are the optimal solution to control viscosity. They enrich, stabilize and improve the products. Improved liquid properties lead to superior handling and cost savings.
Surface engineering requires knowledge
A thorough understanding of the rheological requirements of an application is essential to successful product development. The key to this understanding is building a solid knowledge base regarding the effect a change in rheology has on the established critical parameters of a system.
Eka Chemicals' extensive knowledge of the fundamental thickening mechanisms, along with factors which influence these mechanisms, allow you to achieve optimal paper product quality in a predictable and timely manner. Our rheology modifiers can help you increase shear viscosity and improve water retention.
