Abstract

A cone‐plate viscometer was employed for studying the rheological characteristics of certain unfilled resins and etching gels. Of these, BIS‐GMA monomer and its diluted mixtures exhibited Newtonian, dilatant and thixotropic behaviour depending on the shear rate. Other unfilled resins also exhibited various types of behaviour. At high shear rates reproducible hysteresis loops were obtained for etching gels which may be useful in characterization.
