Drying Time Recorder

SHBK3 Drying Time Recorders

The SHBK3 Drying Time Recorder is widely used in the coatings industry throughout the world. A needle carrier holding six hemispherical ended needles travels the length of the six 305 x 25 mm test strips in 6, 12 or 24 hours. Other speeds are available to special order. A time scale on the side cover is graduated to suit the three different travel times.

A time scale on the side cover is graduated to suit the three different travel times. SHBK6 and SHBK10 Drying Time Recorders SHBK6 The SHBK6 and SHBK10 Recorders have independently operating tracks allowing tests to be made at different start times. Pairs of tracks operate at the same speed, and a wide range of travel times are available. The standard models are supplied with all tracks traversing at 12 hours, however, alternative combinations of speeds of 6, 12, 24 and 48 hours can be specified at the time of ordering. A time scale on the front cover is graduated to suit the instrument’s drying time ranges. Each pair of tracks has its own individual operating switch. Drying Stages Initially the needle passes through the film followed by defined stages in the drying process that can be identified as: The needle passes through the film, it recovers to leave no trace, progressing to a pear shape impression, corresponding with the evaporation of the solvent. Cutting of a continuous track corresponding to a sol-gel transition. The track depth is reducing and becomes interrupted corresponding to a tack-free surface-dry time. The needle no longer penetrates the film, corresponding to the final drying time. Brass weights (supplied as an accessory), each weighing 5 grams, may be used to apply greater pressure on the needles and thus record the through-drying properties of alkyds, varnishes and paints. The BK Drying Recorders will give useful information about the gelation times of many two component surface coating materials, and the properties of such films.

Slip and Friction Tester

Introduction

The Slip and Friction Tester is designed to measure the sliding resistance of sheet like materials including plastic film, packaging film laminates, paper, paperboard and coated surfaces.

For over 30 years, Testing Machines, Inc. has had a history of producing reliable, accurate and robust testing instruments for measuring coefficient of friction. The model 32-07 is our latest design offering advanced features for measuring and automatically calculating static and kinetic coefficient of friction.

Slip and friction testing aids in the evaluation of chemicals and additives used to create or minimize the degree of friction between two contacting test specimens.


Specifications

  • Selectable speed from 5 to 50.8 cm per minute (2 to 20 in per minute)
  • Selectable travel distance from 2.5 to 30.5 cm (1 to 12 in.)
  • Load cell: 10 newtons (1 kg, 2.2 lbs)


Features

  • Digital display, storage and editing of up to 100 readings, and selectable units (COF or grams)
  • Settable limits
  • Statistics-average, standard deviation, high/low results.
  • Report printout with built-in printer
  • RS-232
  • Static and kinetic coefficient of friction calculated in one operation.
  • Direct drive arm with unique skid control.
  • Sled-connecting mechanism ensures level pulling action.
  • Easily interchangeable sleds.
  • Full color, easy-to-read display

Krebs Viscometer

Features

  • Range: 54-140 KU (75-1000 g.)
  • Sturdy mechanical assembly & easy maintenance
  • Easy to read speed indication
  • Good value for money
  • Standard package: Viscometer, paddle rotor,
  • 1 pint (500 ml) / Ø85 mm can,
  • Set of 7 weights (2 x 5g, 1 x 10g, 1 x 25g, 1 x 50g, 2 x 100g,
  • 1 x 200g, 1 x 500g), AC/DC 12V adapter (for digital version)


Information

This traditional KREBS viscometry instrument uses a rotating paddle driven by falling weights to determine the paint viscosity. The viscosity value in Krebs units can be easily converted using the table supplied or by calculation by formula from the resultant value of total weight required to reach 200 rpm.

The robust and simple construction of this viscometer allows it to be used in various environments.
2 versions available: with tachometer or with stroboscope.

Digital Rotothinner™

Features

  • Quick release chuck for rapid rotor change and cleaning
  • Multipoint calibration
  • Remote calibration key for extra security
  • Storage facility and RS232 output for printer


Information

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

Rotothinners allow the operator to continuously monitor the samples viscosity whilst a solvent or thinner is added. This allows quick correction factors for use in the production batch when carried out quantitatively.

The viscosity is measured using a high quality microprocessor controlled DC motor. The robust construction of the Rotothinners means that they are suitable for use as both production and laboratory instruments. Supplied with a 250ml sample tin.

Flow Cups

Flow cups, originally designed to perform quick viscosity and consistency evaluations of Newtonian or near non-Newtonian products, can provide a high degree of accuracy and repeatability depending on the quality of their manufacture.

Our flow cups are manufactured in accordance with International Standards which not only specify the close dimensional tolerances required during the process but also their use and recording of data obtained.

With our long established experience in the manufacture of these types of products, Sheen flow cups offer outstanding testing quality. They are produced from selected high grade materials, with the latest computerised machining technology under stringent quality control conditions. A smooth, bright finish makes them easy to use and clean for a long lasting operating life.

Conformance certificates are included with all our flow cups to the relevant National Standard. Calibration certificates according to calculation data given by the relevant standard, or to internal comparative procedures are available upon request when ordering.

To ensure optimal accuracy of your testing results, a periodic calibration check of your cups is strongly recommended, either by our own calibration department, or alternatively by using our range of standardised calibration oils.
