Viscosity Viscosity The extent to which a liquid resists a tendency to flow is defined as viscosity. In the coatings industry, this behaviour is one of the key parameters. Elcometer manufactures and supplies a wide range of viscosity gauges from flow cups and dip cups to rotational and cone and plate viscometers. Flow Cups: The process of flow through an orifice can often be used as a relative measurement and classification of viscosity. This measured kinematic viscosity is generally expressed in seconds of flow time which can be converted into Centistokes using a viscosity disc calculator. Dip Cups: Using the same principle as flow cups, dip cups Frikmar, Zahn, Shell, etc. can be used to provide a quick viscosity measurement on the shop floor or on site. Rotational: Rotational viscometers are used to determine the viscosity of liquids which do not depend solely on temperature and pressure. The behaviour of non-newtonian liquids can be determined using a range of rotational viscometers in particular the Cone and Plate viscometers (see pages 14-17).

Viscosity Elcometer 2280 Matthis Fluidometer A simple and easy-to-use instrument to measure the fluidity of a coating. The product to be measured is poured into a semi-spherical cavity of the instrument, which is in the horizontal position. The instrument is then lifted vertically allowing the liquid to flow under gravity, in the groove, which is graduated in mm. The distance it flows after approximately 10 seconds ±0.5 seconds, measured with the sand timer provided, indicates the fluidity of the coating. Elcometer 2280/1 Matthis Fluidometer K0002280M001 Accessories Spare Sand Bottle KT002280N001 Elcometer 2290 Daniel Flow Gauge This simple instrument is used to assess the ability of thick or paste-like materials such as paints or printing inks to flow. The product is poured into the semi-cylindrical reservoir. When the instrument is lifted vertically, the product runs on a graduated plate, which is fixed perpendicular to the reservoir. The distance covered in a given time is the measure of the fluidity. Elcometer 2290/1 Daniel Flow Gauge K0002290M001 Test Charts see pages 33-38 12
Rotational Viscosity Rotational Viscosity Viscosity A measure of the resistance of a liquid to flow. Thixotropic Describes materials that are gel-like at rest but liquid when agitated. Centipoise A unit of measurement of which water is the standard at 1cP. Newtonian Liquids The viscosity of a Newtonian liquid is dependent only on temperature, not on shear rate and time. Non-Newtonian liquids - time dependent. The viscosity of the liquid is dependent on temperature, shear rate and time. Depending on how viscosity changes with time the flow behaviour is characterised as: Thixotropic (time thinning, i.e. viscosity decreases with time). Rheopetic (time thickening, i.e. viscosity increases with time). Thixotropic liquids are quite common in the chemical and food industries. Rheopectic liquids are very rare. Note: some liquids show time thinning behaviour due to breakdown of structure. This phenomenon is sometimes known as Rheomaiaxis. Non-Newtonian liquids - time independent. The viscosity of a Non-Newtonian time independent liquid is dependent not only on temperature but also on shear rate. Depending on how viscosity changes with shear rate, the flow behaviour is characterised as: shear thinning also known as Pseudoplastics - the viscosity decreases with increased shear rate. shear thickening also known as Dilatant - the viscosity increases with increased shear rate. plastic - exhibits a so-called yield value, i.e. a certain shear stress must be applied before flow occurs. Elcometer 2200 Digital Viscometer This simple to use rotational viscometer consists of a spindle and paddle. The spindle is rotated at 200rpm and, when the paddle is immersed in the sample coating, the Elcometer 2200 automatically calculates the viscosity value from the power required to maintain the spindle at 200rpm.

Rotational Viscosity Elcometer 2205 Analogue Cone & Plate Viscometer The Elcometer 2205 Cone and Plate Viscometer has been designed specifically to provide high shear rate tests for coatings. Running at a single speed of 900rpm (60Hz) or 750rpm (50Hz), the Elcometer 2205 Analogue Cone and Plate Viscometer comes in two model variations: Low Temperature s - Choose from either a range of single pre-set temperature models or a single model with three pre-set temperatures. High Temperature s - Supplied in 3 temperature ranges with 6 pre-set temperatures. The low temperature Viscometer: Designed to facilitate routine measurement of the viscosity of paints. Good correlation with application methods (e.g. brushing) is ensured by the use of a high rate of shear (10,000 sec -1 ). The cone and plate principle is selected because this is one of the most convenient ways of obtaining high rates of shear. The ranges of measurement of 0-2, 0-5poise and 0-10poise are chosen as suitable for most normal paints. Alternative rates of shear or ranges of measurement can be obtained by using cones of alternative size or angle see page 17 for the range of cone types available. BS 3900 A7 ASTM D 2196 Temperature control is essential in measuring the viscosity of paint. This Viscometer has a built-in provision for holding the sample at the temperature regardless of normal variations in the bulk sample or in room temperature. Heating or cooling of the sample is by a Peltier effect semi-conductor device. The sample reaches the control temperature in no more than 15 seconds. The high temperature Viscometer: Designed for the control of the viscosity of resins, bitumen, hot melts and similar products, during manufacture. These Viscometers enable a very small sample from the cooking vessel to be checked for viscosity in less than a minute. The instrument is thermostatically controlled over a wide range of temperatures, one of which is selected so that the melt viscosity of the resin comes within the viscosity range of the instrument. In this way, thinning tests are eliminated and a quick and accurate determination of resin viscosity is obtained. Ease of cleaning is ensured by the small sample required and the ease of access made possible by the simple geometry of the cone and plate principle. A wipe with paper tissue and suitable solvent is all that is normally required.

Although manufactured in a rugged design needed for manufacturing, the Elcometer 2206 has a range of features to meet the ever demanding controls on modern production standards. A range of low and high temperature models are available to meet your exact requirement. Choose either a single temperature, 3 or 6 pre-set temperatures or set your own temperature using our variable temperature model. Used in the paint, varnish, inks, resins, food, bitumen, oil, adhesives and pharmaceutical industries. The low temperature Viscometer: Designed to facilitate routine measurement of the viscosity of paints. Good correlation with application methods (e.g. brushing) is ensured by the use of a high rate of shear (10,000 sec -1 ). The cone and plate principle is selected because this is one of the most convenient ways of obtaining high rates of shear. ASTM D 4287 BS 3900 A7 The ranges of measurement of 0-2, 0-5poise and 0-10poise are chosen as suitable for ISO 2884 most normal paints. Alternative rates of shear or ranges of measurement can be obtained by using cones of alternative size or angle. Temperature control is essential in measuring the viscosity of paint. This Viscometer has built-in provision for holding the sample at the temperature regardless of normal variations in the bulk sample or in room temperature. Heating or cooling of the sample is by a Peltier effect semi-conductor device. The sample reaches the control temperature in no more than 15 seconds. The high temperature Viscometer: Designed for the control of the viscosity of resins, bitumen, hot melts and similar products, during manufacture. These Viscometers enable a very small sample from the cooking vessel to be checked for viscosity in less than a minute. The instrument is thermostatically controlled over a wide range of temperatures, one of which is selected so that the melt viscosity of the resin comes within the viscosity range of the instrument. In this way, thinning tests are eliminated and a quick and accurate determination of resin viscosity is obtained. Ease of cleaning is ensured by the small sample required and the ease of access made possible by the simple geometry of the cone and plate principle. A wipe with paper tissue and suitable solvent is all that is normally required.
