Highly functionalized surface additives can provide industrial coatings and printing inks with a durable, lubricant surface that is easy to clean. Siloxane-based additives play a major role in the performance of many of these high-performance formulations. The use of organo-modified polysiloxanes in surface additives is growing beyond the typical applications in wetting agents and defoamers. Due to their unique interfacial activity, modified siloxanes are invaluable ingredients that promote smooth film surfaces by improving leveling and minimizing craters. This also results in functional surface properties such as slip or easy-to-clean effects.¹ Details of the chemistry and resulting performance attributes of a new, highly compatible, organo-modified, highly functional siloxane-based ETC additive (OHSA) are presented here.
