International. A team of Iranian researchers recently proposed a new method to increase scratch resistance in the transparent layer of cars.
Over the past few decades, efforts have been made to improve the automotive resistance of transparent layers against abrasive and erosive wear. As a result, a number of techniques have been proposed for this purpose. A recent example of the latter involves the use of silicon-based additives to give better anti-scratch quality to applied surfaces.
The aforementioned researchers managed to integrate 40 nm modified silica nanoparticles into a transparent layer of acrylic/melamine, to obtain superiority in terms of scratch resistance. In addition, they established an innovative routine to investigate the morphology and characteristics of scratching by means of gonio-spectrophotometry.
According to the results of this research, the application of nano-sized particles allows the achievement of greater degrees of improvement in properties, compared to conventional silicon-based additives. In other words, nanoparticles can influence the coating curing process and form a physical network of particles/coatings that resist scratches.
