Abrasion is one of the most important defects that deteriorates the durability of coatings. The goal of the research presented in this article was to achieve a good understanding of the effects of coating additives on the abrasion resistance of waterborne coatings.
To obtain continual improvements in scratch- and abrasion-resistant coatings, a variety of additive technologies have been developed to address this issue. In this study, the article examines additive technologies ranging from surface-active siloxanes and nanocomposite technology to synthetic amorphous silica and co-binders.
The commercial success of silicone resins in the field of high-temperature-resistant coatings is based on their special properties. Alongside the classic heat-curing systems, ambient-curing systems are enjoying ever greater success.
Both the mechanical impact strength characteristics and resistance to atmospheric effects improve with increasing concentration of silicone elastomer particles.
Traditional two-pack PUR technology combined with surface-modified nanosilica particles results in increased scratch and abrasion resistance in transparent, high-gloss coatings for plastics.
