HOMBITAN MCT 300 –A Highly sophisticated pigmentHOMBITAN MCT 300 is a cutting-edge anatase pigment speciallytailored for use in highly sophisticated applications. This productassures important benefits for users, including good rheological(flow) properties and low dust generation; it is readily wettablein a large range of polymer systems, assuring high throughputrates. HOMBITAN MCT 300‘s excellent dispersibility permitsproduction of extremely thin films, and of laminated films, withexceptionally low lacing, even at high loadings and temperatures,with minimized pressure increase at melt filters.HOMBITAN MCT 300High-qualityanatasepigmentsStandardanatasepigmentsWith its anatase structure, HOMBITAN MCT 300 imparts a highbluish tint to white products, while simultaneously reducingabrasive wear on processing equipment. HOMBITAN MCT 300has no effects on product odour or taste. The recommendedapplications for HOMBITAN MCT 300 include food packaging,thin films, co-extruded laminated films, laminated containers,coatings for masterbatches, credit and bank cards, blister packaging,polyolefin fibers etc.Pressure filter test(hombitan mct 300 sample)PRESSURE [bar]1008060402000 10 20 30 40 50TIME [min]PF: 0.12 bar • cm 2 /gTest Parameter1.
