Release Agent Composition For Solid Inkjet Imaging Systems For Improved Coefficient Of Friction

摘要

A functional amine release agent displaying reduced coefficient of friction as compared to standard silicone oils, the release agent comprising a polydimethylsiloxane oil and a functional amine selected from the group consisting of pendant propylamines and pendant N-(2-aminoethyl)-3-aminopropyl; wherein the concentration of functional amine to polydimethylsiloxane oil is approximately less than 0.0006 meq/g. According to certain embodiments, the functional amine release agent is operable to impart a coefficient of friction of about 0.3 or more to the print media, resulting in improved finishing and converting equipment interaction.
