When Temperature Talks: How Thermochromic Pigments Transform Materials

Thermochromic pigments, such as Chromazone®, enable formulators to create products with dynamic and heat-sensitive, colour changes. These smart materials have found their way into various applications, from functional safety indicators to eye-catching promotional products. For example, reversible thermochromic pigments are used in novelty mugs that reveal hidden designs when filled with hot beverages, packaging that signals when food or drink is at the optimal temperature for consumption, security labels for brand protection and anti-counterfeiting, and temperature-sensitive warning indicators on surfaces or medical devices.

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.
