  • Publication number: 20160067956
    Abstract: A functional amine release agent displaying reduced coefficient of friction as compared to standard silicone oils, comprises a polydimethylsiloxane oil and a functional amine selected from the group consisting of pendant propylamines and pendant N-(2-aminoethyl)-3-aminopropyl. The concentration of functional amine to polydimethylsiloxane oil is approximately less than 0.0001 meq/g. According to certain embodiments, the functional amine release agent is operable to impart a coefficient of friction of about 0.5 or more to the print media, resulting in improved finishing and converting equipment interaction. The release agent may have a viscosity of about 50 cSt.
