ABSTRACT:
An improved lubricant for coating moving webs is provided. The lubricant includes a chemically modified lecithin, such as hydroxylated or acethylated lecithin, and a fatty ester to completely eliminate the need for a surfactant in the composition. The mixture avoids foaming while maintaining the coating structure, even at high speeds found in modern printing equipment and processes. The lubricant improves coating rheology and maintains coating structure. The lubricant maintains a homogeneous coating, even at high speeds, thus resulting in superior coating and paper characteristics.
