1 ABOUT YOUR DRYING TIME RECORDER

The Elcometer 5300 Ball Type Drying Time Recorder is used to determine the

drying time of paint and other coatings such as glue, cosmetic products,

varnish, inks, biologic material and adhesives.

A layer of the coating is applied to a glass surface and a stainless steel ball is

dragged across the glass as the coating dries. At the end of the test the Drying

Time Recorder stops automatically and the imprint of the ball on the coating

surface is examined to determine the point at which the coating dries.

The Elcometer 5300 Ball Type Drying Time Recorder has ten separate lanes

which allow ten different coating formulations to be tested simultaneously.

The load on each ball is 11 g, however this can be increased to 21 g using the

supplied weights.

1.1 What the box contains

• Elcometer 5300 Ball Type Drying Time Recorder

• 12 glass strips

• 10 x 10 g weights

• Operating instructions

Your Elcometer 5300 Ball Type Drying Time Recorder is packed in a cardboard

and foam package. Please ensure that this packaging is disposed of in an

environmentally sensitive manner. Consult your local Environmental Authority

for further guidance.

To maximise the benefits of your new Elcometer 5300 Ball Type Drying Time

2.2.2 Carriage start/stop

To start the carriage, press the carriage start/stop button. The carriage will stop

automatically when it reaches the end of the test.

2.2.3 Carriage speed

Your instrument has six carriage speeds which are selected by rotating the

carriage speed selector on the left side of the machine.

2.2.4 Moving the carriage

To move the carriage to the start position (or any other position), disconnect the

carriage from the drive mechanism by rotating the drive coupling knob

clockwise. When the carriage is uncoupled, the carriage can be pushed by hand

to any position. Rotate the drive coupling knob anticlockwise to reconnect the

carriage to the drive mechanism.

2.3 Caution

The Elcometer 5300 Ball Type Drying Time Recorder has been manufactured

with your safety in mind. However, improper use can result in damage to the

machine.

Please observe the precautions discussed in these operating instructions.

To reduce the risk of electric shock, do not open the housing of the

Drying Time Recorder. There are no user-serviceable parts inside.

To reduce the risk of fire or electric shock, do not expose the Drying

Time Recorder to rain or excess moisture.

The mains plug on your Drying Time Recorder may be fitted with a fuse. When

replacing this fuse, ensure a fuse of the correct rating is used.

3 TESTING A SPECIMEN

1. Connect the Drying Time Recorder to the mains supply.

2. Switch on the instrument.

3. Adjust the height of each ball so that it is perpendicular to the glass

specimen and then tighten the thumb screw. In this position the tool

provides a load of 11 g ± 1.5 g. Do the same for all 10 balls.

4. Apply the coating to the glass plates using an Elcometer 3505 Cube Film

Applicatora(Figure 2).

Figure 2. Applying the coating using an Elcometer 3505

5. Place the glass plates on the instrument.

6. Rotate the drive coupling knob clockwise and push the carriage to the 0

(start) position. Rotate the drive coupling knob anti-clockwise to connect the

carriage to the drive mechanism.

a. To order an Elcometer 3505 Cube Film Applicator, see “Accessories” on page 9.

7. Rotate all the balls down onto the specimens (Figure 3).

Figure 3. Rotate the balls down onto the specimens

8. If necessary, add the 10 g weights to increase the load.

9. Set the carriage speed using the carriage speed selector.

10.Press the carriage stop/start button.

The carriage will travel along the length of the specimens and will stop

automatically at the end of its travel.

11.At the end of the test, rotate the balls away from the specimens.

12.Using the guidelines given in the test standardb, examine the specimens to

determine the position on the trace where the coating dried. By moving the

carriage to this position, the distance can be read from the graduated scale

on the body of the instrument. Divide this distance by the carriage speed to

give the drying time.

13.When the test is completed, clean the balls and glass plates thoroughly.

b. See “Specimen trace analysis” on page 7 for an example of a typical trace analysis.

4 SPECIMEN TRACE ANALYSIS

The following example of how to analyse the trace left by the balls on a paint

coating is taken from the standard NF T 30-037.

Figure 4. Specimen trace analysis

1. Levelling: Because paint flows when it is wet, the trace is covered by paint

after the ball has passed, therefore no permanent trace is left in the paint

film.

2. Basic trace: The paint has started to dry.

3. Setting: The paint film is ruptured by the ball. At this stage dust will not

adhere to the paint film.

4. Surface dry: A skin has formed over the paint. At this stage the paint does

not adhere to the ball.

5. Dry: The paint is no longer marked by the ball.
