The influence of surface physicochemistry of solid fillers on dispersion in polyurea systems
Abstract
Polyurea coatings are obtained by hydrodynamic spraying by means of high-pressure, spray-coatingequipment. A chemi-cal reaction between the isocyanate and amine components occurs in the time of approximately 6 seconds, which enables use of the coated object almost immediately after coating application. Polyurea coating modificationresults in changes in their properties and a cost reduction. In this work modifiers such as expanded graphite, talc and chalk, which are inexpensive, eas-ily commercially obtainable fillers were employed. The curing degree was measured by FT-IR spectroscopy, thermal stability by thermogravimetric analysis (TG) and phase transition temperatures by differential scanning calorimetry (DSC). For the systems stored under different conditions, the tensile strength and Shore hardness in the D scale were also measured. SEM/EDS analysis was performed to assess the dispersion of the modifiers in the polyurea coatings. To determine the hydro-phobic-hydrophilic character, contact angle analyses were performed. The addition of the fillers improves some of theparameters, e.g. the thermal stability and mechanical properties.
