Synergism in anticorrosive paints

Antioxidative and Anticorrosive Properties of Bioglycerol

Raw glycerol fraction (also called bioglycerol) is the second product of fatty acids triglycerides alcoholysis. However, by many biodiesel producers it is treated as a waste, unwanted material. Due to overproduction of the glycerol fraction there have been many attempts to find its proper utilization, especially that it can comprise up to 30% of the whole biodiesel production. Finding proper ap...

How a painter paints

Drawing from the seminal definition of the principles of abstract art posed by Wassily Kandinsky in the early years of the twentieth century, and contextualizing that knowledge in contemporary cognitive metaphor theory (Lakoff & Johnson, 1999), the study attempts to arrive at an understanding of how cognitive structure emerges in pragmatic self-observation during the artistic process.

It is only since the nineteenth century that houses have commonly been painted. Today paints are used for colouring and protecting many surfaces, including houses, cars, road markings and underground storage vessels. Each of these different applications req...

Paints and Coatings

Visibility of sparkle in metallic paints.

For suitable illumination and observation conditions, sparkles may be observed in metallic coatings. The visibility of these sparkles depends critically on their intensity, and on the paint medium surrounding the metallic flakes. Based on previous perception studies from other disciplines, we derive equations for the threshold for sparkles to be visible. The resulting equations show how the vis...
