Automatic Film Applicators

Click picture for close up view

Sheen Automatic Film Applicators remove the variability between operators to produce consistent draw downs and allow reliable sample comparisons to be made. Consistent speed, shear rate and applied downward pressure are factors that eliminate human error.

Speed is adjustable from 50 to 500 mm/s and 2-4 preset speeds can be set according to the model. Sheen Wire Bars and all types of applicators can be used to lay the film.

The vacuum applicator has a built-in vacuum pump, a large precision-machined perforated aluminium bed and is available in two sizes to suit your requirements. The large, glass bed model includes spring clips for easy sample fixing. A smaller rubber bed model is also available.

Calibration Oils

Viscosity flow cups and rotational viscometers can be calibrated with these premium quality, UKAS certified and traceable viscosity standards conforming to BS EN ISO IEC.

Sheen and Cannon calibrated oils are available to cover a wide range of applications from low to high shear. Supplied in 500ml bottles, precision is +/- 0.3% for dynamic and kinematic viscosity.

The standard range (Ref 442) is calibrated between 20-25 degrees C. The general range is calibrated between 20-100 degrees C. The Cannon range is calibrated between 20-26 degrees C, traceable to NIST and in 460ml bottles.

Cone and Plate Viscometer

Paints, inks and other products with non-Newtonian viscosity, show flow behaviour changes under high shear rates (such as when they are applied with brush, roller or spray gun).

The Sheen Cone and Plate viscometer is designed to produce shear rates of 10,000 sec-1 and accurately measure product viscosity under typical application conditions.

This instrument has many user-friendly features including five interchangeable cone kits covering 0-5 to 0-100 Poise ranges, a quick release chuck for easy cleaning, calibration by user and easy menu-guided operation.

Krebs Viscometer

The Krebs Rotating Paddle Viscometer is a simple means of determining the viscosity of non-Newtonian fluids.

The digital version has a constant speed motor rotating at 200 rpm for greater accuracy and repeatability, and removes the need for the separate weights used in older models.

A quick release chuck enables rapid cleaning and changeover of the paddle, and the integrated digital display gives the reading in Krebs units, grams or poise.

The Ref 480 Digital Krebs Viscometer uses multipoint calibration across the torque range for high precision, and a remote calibration key allows the instrument to be secure from accidental adjustment.

A magnetic base holds the sample container in place.

Rotothinner Viscometer

Convenient in-plant production control or fast QC laboratory viscosity measurements are possible using the Sheen Rotothinner Viscometer.

This robust instrument is designed for the factory environment and is widely used throughout the coatings industry. A sample from production can be measured and the viscosity corrected whilst in the Rotothinner, enabling the thinning ratio for the batch to be determined quickly.

Three models cover ranges 0-15, 0-65 and 1-340 Poise with accuracy +/- 2%.

The Rotothinner instrument uses a disc or ball shaped rotor to determine the viscosity of the sample under test. The results are displayed directly on the LCD screen in POISE units.

Adjustable Film Applicator

Two knurled screws on this rugged applicator allow a doctor blade gap size of up to 6000um to be set. The bevelled blade reduces shear so that the resultant wet film thickness is much closer to the actual gap clearance than other gap applicators.

Film width is 76mm.

Micrometer Adjustable Film Applicator

Two micrometric screws accurately adjust the gap from zero to 8mm in 10um steps, making this applicator suitable for many tasks where different coating thicknesses are required.

Research projects and fabric coating are popular uses for this instrument. 5 film widths from 100 to 300mm are available.

The new Sheen Glossmaster glossmeters now offer even greater versatility and ease of use, and superior data handling capabilities.

Gloss is an important attribute of surface appearance. It changes our perception of colours and shapes and influences our overall visual experience.

The new generation Glossmaster range offers increased performance and versatility with enhanced, user friendly features. Quality Control is made easier by more powerful data processing capability, and many difference calculations and pass-fail functions.

Easy-link software is included for data downloads to Microsoft Excel. The standard templates produce professional QC reports.

Tri-Glossmaster 20-60-85 degrees combine three angles in one instrument to cover all gloss levels from matt to high gloss. Single angle Glossmasters 20, 60 or 85 degrees are used for matt, general purpose and high gloss respectively.

The Sheen Pneumatic Panel Sprayer was developed in association with world major paint companies to produce perfectly reproducible sprayed samples.

Reliable testing of high performance coatings such as metallics and pearlescents requires the constant panel quality delivered by this machine.

The programmed settings provide strict control of parameters such as atomisation, flow, thickness, uniformity, film build, drying, etc, to produce consistent coated panels - Impossible to achieve manually!

The Sheen Pneumatic Panel Sprayer is easy to operate and all functions and movements are air operated. This makes the Srayer suitable for use in hazardous environments.

A wide range of options is available to enable this unit to be used across a wide range of applications.

Payne Permeability Cup

Reliable measurement of the permeability of a coating or film to water vapour or other volatiles is easily accomplished with this simple instrument.

A sample disc of the dried coating on a permeable backing or a test film clamped on the cup give a precise exposure area of 10 cm² or 25 cm². The cup holding 5 cc of water is placed in a desiccator and weighed every 24 hours to check the loss of water by permeation through the film.

FOGmaster Salt Spray, Humidity and Corrosion Cabinets

Click picture for close up view

The Sheen Fogmaster range of test cabinets accelerate the harsh effects of humidity, salt spray, condensation and air drying enabling early assessment of coating or product performance and formulation modifications.

Fogmaster Humidity Cabinets create a fixed high humidity at user-adjustable temperatures to simulate situations where condensation forms on a surface. Corrosion resistance and degradation under conditions of condensing or saturated humidity can be reliably evaluated.

Fogmaster Salt Spray Cabinets produce a controlled continuous or intermittent salt spray for ascertaining corrosion resistance of formulations and processes according to various international standards.

Fogmaster Cyclic Corrosion Test (CCT) Cabinets can be programmed to create a user-defined corrosion cycle that can be continuously repeated. The cycle climates can include condensing humidity, salt spray, air drying and optional controlled humidity at adjustable temperatures and times. These cabinets enable the prediction of "real world" service life expectancy under natural exposure conditions.

The Viscomaster range of spindle viscometers from Sheen are the ideal solution for performing precise viscosity measurements quickly and efficiently.

Ease of use and versatility enable them to be used in many industrial applications where the determination of fluid properties and behaviour is essential.

The principle of measurement is simple, but reliable, based on the well-established method of measuring the resistance of a spindle rotating in the sample under test.

The resultant torque measurement, rotational speed and spindle properties are then combined to automatically calculate the resultant viscosity value.

Features:

• Measuring range - 100 to 13,000,000 cP.
• Fixed speeds from 0.3 to 200 rpm.
• Direct readout on clearly illuminated 4 line LCD displaying selected operating parameters.
• Senses and displays continuously:- Viscosity (cP or mPa·s) ; Temperature ( Degrees C or F) ; % scale ; Speed (rpm) ; Spindle used.
• Progressive deceleration avoids excessive torque on spindle when stop is selected.
• Temperature reading with platinum probe.
• Density input allowing kinematic viscosity determinations.
• Auto-range function.
• Storage of 10 user-defined test settings.
• Range of accessories available.
