Abstract
Because additives have been around for decades, they have never diminished from our focus in formulations. Even though additives represent a minor portion of a formulator’s paint or ink formula, without them surface defects can be significant. In particular, silicone additives bring to the coatings’ table a range of surface-modifying and enhancing properties. As a result of the increasing pressure to reduce VOCs, UV-curable technology is experiencing a significant growth in the market. This paper will look at the technological advancements of silicone additives as they have progressed through simple polyether modification, which helped overcome incompatibilities in coatings formulations. The more reactive functional modifications that silicones are heading towards still help to maintain compatibility but offer more permanent results. Typical coating film defects such as cratering and orange peel are avoided, and the negative effects of floating can be suppressed. Furthermore, these additives provide smooth surfaces as well as improving the gloss and allowing the coating to be more scratch resistant.
