As UV coatings continue to be applied to a broader range of substrates, the demand for scratch and abrasion resistance continues to grow. This is especially true with thin-film applications over flexible, semi-porous or hard substrates with varying types of gloss or haptic properties. There are a variety of ways in which damage can occur due to various geometries and forces of the objects scraping over the coating surfaces. There are many factors, such as resin composition, surface uniformity and irregularities, etc., that will influence . . .
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.
