This article discusses the basic characteristics of phyllosilicate thickeners, and provides an introduction to understanding their performance in formulations in order to use them to build the rheological properties of latex paints.

A specialty chemicals and minerals supplier offers a case study to compare its novel architectural colorants to industry-standard colorants. Utilizing tests such as viscosity drop, blocking resistance, open time, and base compatibility, these colorants deliver superior performance, an extended shelf life, and offer global compliance, while showcasing their low-VOC and high-pigment-loading capabilities.

Microfibrillated cellulose (MFC), a bio-based and multi-functional product made of cellulose, is a new alternative to traditional thickeners. Learn how MFC increases the tensile strength of elastomeric acrylic roof coatings without sacrificing the elongation, and how it reduces the water absorption, as well as increases the adhesion of coatings.

Concerning rheological stabilization of coatings, there is a trend to move away from hazardous raw materials, with preference given to the use of bio-based and sustainable chemistries, wherever possible. Testing of new organic additives shows good dispensability and ease of activation.

Formulators should use technology to track down the rheological sweet spot for their products and see the lab as a source of knowledge and collaboration. The resulting data will set research projects off on the right path and deliver huge savings for R&D, the company, the customer and maybe even the planet.

In this study, novel testing geometries are used to measure changes in viscoelastic properties of waterborne coatings during drying.

A live DIY consumer roll-out study along with a comprehensive benchmarking study of > 20 commercial paints gave insights into physical paint parameters that result in DIY consumer satisfaction.
