10 Microrheology applications FILM FORMATION ANALYSIS VISCOELASTIC ANALYSIS IN BULK PAINT Monitor in real-time mechanisms and characteristic times of drying of waterborne or solvent-based paints: - Determine accurately the open-time. - Control the dust-free time, touch-free time, dry-hard time, etc… - Monitor effect of a thickener or additive. INK Study drying kinetics on any substrates (glass, wood, plastic, paper, etc…) - Gravure inks. - Paper inks. - e-inks. COSMETICS Control the drying properties of cosmetics products with a better accuracy: - Drying of nail varnishes. - Evolution of a mascara. - Crystallization of lipstick. & MANY OTHERS Thanks to this versatile technology, explore the drying properties of various systems in many other application fields: - UV-curing of specialty products. - Control the drying of glues. - Etc... FOOD - Monitor gelation of yoghurts versus time, temperature or pH. - Characterize the texture of salad dressing, creams, mayonnaise, etc… HOME & PERSONAL CARE - Determine ideal concentration of softeners to reduce packaging size. - Control the texture of cosmetic creams or toothpastes. - Analyse the rheology and stability of shampoos. PHARMACEUTICALS - Adapt thickener concentration for cough syrups. - Control the gel properties of eye-drops. - Characterise the rate of delivery of polymer-based drugs. PAINT & INK - Control the texture and behaviour of non-drip paints. - Monitor the speed of recovery after application of the paint (brushing, spraying…). MATERIALS - Determine the pot-life of composite components. - Monitor effect of additives on cement setting. & MANY OTHERS - Measure the rheology of polymer dispersions for Oil Recovery. - Characterise the behaviour of slurries, lubricants, etc… BENEFITS NON CONTACT MEASUREMENT Measurement is performed without any mechanical stress. It allows the analysis of fragile materials (weak gels, creams, etc…) without sample modification nor destruction. VISCOELASTIC PROPERTIES VS. TIME • Gelation process ; • Structure recovery ; • Long-term stability ; EASY SAMPLE HANDLING • No evaporation or drying (Rheolaser) / Open environment (Horus); • No geometry configuration ; • Disposable measurement cell (Rheolaser) ;
RHEOLASER: explore rheology at rest The Rheolaser is dedicated to formulators interested in the end-use properties of their products, such as gelation, stress recovery, shape stability, long-term stability & many others... The Rheolaser Master is specifically designed for monitoring viscoelastic evolutions such as SOL-GEL transition (gelation), viscoelastic changes during ageing or recovery, on the very same sample. It also includes l* measurement (optical transport path of the photons) to monitor in real-time any dispersion state variation in the sample, such as particles size variation or particles migration. MAIN ADVANTAGES • Measurement AT REST (zero-shear), non-intrusive & non-destructive. • One-click experiment & results (no parameters needed) • Ageing analysis on the very same sample, with an easy sampling • Hazardous samples can be analysed in a closed glass cell KEY PARAMETERS These parameters are kinetics, meaning the user can monitor the evolution of any product versus ageing time. SOLID-LIQUID BALANCE (SLB), ratio between the solid-like and the liquid-like behaviour of the studied sample. - Monitor properties such as: adhesion, spreadability, gel point, shape stability, physical stability, etc... ELASTICITY INDEX (EI), elasticity strength in the studied sample. - Monitor properties such as: mesh/pore size, hardness, recovery, gelation, etc... MACROSCOPIC VISCOSITY INDEX (MVI), quantify and compare the macroscopic viscosity at zero-shear. - Monitor properties such as: effect of a thickening agent, texture, flowability, long-term stability, etc... TIME CURE SUPERPOSITION (TCS), determine gel points with great accuracy. Rheolaser Range RHEOLASER LAB & LAB6 RHEOLASER Basics of the technology for microrheology analysis The first ready-to-use microrheology instrument to analyse formulated products such as creams, gels or polymer-based emulsions. • 6 storage positions • Up to 6 simultaneous measurements • From RT to 60°C The new spearhead of the microrheology range The new state-of-the-art device, dedicated to monitoring evolution of the rheological properties, such as viscoelasticity change versus ageing time, or sol-gel transition with high accuracy thanks to the Time Cure Superposition method (see page 9) • 6 simultaneous measurements • From RT to 90°C • Time Cure Superposition treatment for accurate gel point determination • l* to monitor macroscopic evolution (size and concentration) 11
