Study on the Rheological Property of Fluorin-silicon Resin/Urushiol Composite

The rheological property of fluorin-silicon resin/urushiol composite system was studied.The rheological behavior,rheologial style,thixotropy and structure-resume velocity of the composite with different proportion were examined.The results indicated that all n values of the composite are less than 1,belonging to a pseudoplastic fluid.The composite also is a thixotropic fluid,its viscosity is related to shearing time,and the viscosity decreased with the increase of shearing time under constant shearing speed of 80 s-1,showing its appropriate thixotropy and structure-resume speed which are beneficial to control the appearance and performance of coatings.
