Release agent composition for tandem solid inkjet imaging systems having improved wettability
View Patent ↗Functional amine release agents displaying improved wetting as compared to standard silicone oils comprise a polydimethylsiloxane oil and a functional amine selected from the group consisting of pendant propylamines and pendant N-(2-aminoethyl)-3-aminopropyl, in which the concentration of functional amine to polydimethylsiloxane oil is approximately less than 0.0006 meq/g and the release agents have a viscosity of 20 cSt and 10 cSt. In an in-line tandem print system, the 20 cSt release agent is used in the upstream print engine while the 10 cSt release agent is used in the downstream print engine.
1. A functional amine 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;
whereby the concentration of functional amine to polydimethylsiloxane oil is 0.0006 meq/g and the release agent has a viscosity of 10 cSt.
2. The functional amine release agent of claim 1 , wherein the print media is paper.
3. The functional amine release agent of claim 2 , wherein the functional amine release agent is operable to reduce the coefficient of friction of print media when placed in contact with said media by no more than 0.1.
