1 ABOUT THIS INSTRUMENT

The Elcometer Film Applicator is a simple but effective instrument for applying a uniform and reproducible

film of product to a flat and relatively firm substrate.

The applicator is set to the required gap and then placed on the substrate

. Product is poured onto the

substrate either in front of the blade, or into the reservoir of models which have this feature. The applicator

is then pushed across the substrate

by hand or by a motorised film applicator to produce the film.

1.1 STANDARDS

Depending upon model, Elcometer film applicators can be used in accordance with the following National

and International Standards: ASTM D 823, FTMS 141aM4121, FTMS 141a4122.1, FTMS 141a2161, FTMS

141a2162, FTMS 141a6226, FTMS 141a4121 and FTMS 141M6226.

a. Elcometer 3800/3805 models are loaded with a contrast sheet. The contrast sheet is pulled out of the applicator by

hand to produce 2 or 3 strips of product on the sheet.

2 SETTING THE BLADE GAP

Take care while you are handling and using your Elcometer Film Applicator. Damage to the working

surfaces will affect the film thickness and the instrument may have to be replaced.

1. 3600: Rotate the two blade retaining knobs to loosen the blade.

3505/3700/3800/3805: Use the hexagonal wrench to loosen the two blade retaining screws.

2. 3505/3600/3700: Place the applicator on a flat and clean reference surface such as a glass plate.

3. For 3505/1, 3600/1, 3600/2, 3600/3, 3700/3, 3800/1 and 3805/1

detach the appropriate thickness gauge from the set and slide it

under the centre of the blade; ensure that the gauge is under the

blade only and not the body of the applicator as well.

For 3505/2, 3600/4, 3600/5, 3600/6, 3700/1 3700/2 detach the

appropriate thickness gauge from each of the two sets and sldie the

gauges under the blade at each side; ensure that the gauge is under

the blade only and not the body of the applicator as well.

4. Press down firmly on the blade and the body of the applicator

ensuring that the blade is flat against the thickness gauge.



5. 3600: Keeping downward pressure on the blade and applicator, rotate

the two knobs to tighten the blade.

3505/3700/3800/3805: Keeping downward pressure on the blade and

applicator, tighten the two blade retaining screws.

6. Use the thickness gauges to confirm that the blade is set to the correct

gap. Adjust if necessary.

The applicator is now ready for use.

3 APPLICATION PROCEDURE

Before each use, check the working surfaces for irregularities and damage.

3505/3600/3700

1. Fix a clean substrate on a flat and horizontal base such as a vacuum table.

2. 3505 only: If applying a film to a glass substrate, fit the guide plate to the side of the applicator.

3. Place the applicator down at one end of the substrate. The applicator should be positioned with the

blade facing away from the direction of travel.

4. 3600: Spread sufficient product on the substrate over a width slightly smaller than the internal width of

the applicator.

3505/3700: Pour a quantitiy of product into the reservoir of the applicator ensuring that the product is

evenly distributed over the whole width of the reservoir.



5. Spread the film by moving the applicator towards the

opposite end of the substrate at a constant speed.

6. Lift the applicator from the substrate taking care to catch any

product dripping from the applicator before it lands on the

newly prepared film.

3800/3805

1. Place a clean contrast sheet into the applicator and feed it

under the blade assembly.

2. Pour a quantitiy of product into each of the reservoirs of the applicator ensuring

the product is evenly distributed over the width of each reservoir.

3. Apply gentle downward pressure on the blade assembly and pull the contrast

sheet out of the instrument at a constant speed to spread the film strips.

4 CLEANING AFTER APPLICATION

After cleaning, ensure that all materials are removed and that the instrument is dry. Use the case provided

to store the instrument when it is not being used.

Do not use very aggressive solvents or

wire brushes, metal scrapers, metal files or

other metallic tools for cleaning.

Clean the applicator using a suitable

solvent.



5 WET FILM THICKNESS

The thickness of the film produced by your applicator depends on many factors including; the speed of film

application, applicator blade gap setting, surface tension and the viscosity of the product.

6 STORAGE

When stainless steel applicators and the thickness gauges are not being used they must be protected from

rust. Rust can appear when stainless steel instruments are used occasionally and when they have been

handled by users with sweaty hands.

To protect against rust, always dry stainless steel applicators and the thickness gauges after use and apply

a thin layer of oil to the surface before storage. Elcometer recommends the use of an oil which does not

harden during drying such as Castrol Rustilo DW 378.

Always store the applicator and thickness gauges in the case provided.

7 MAINTENANCE

The Elcometer Film Applicator is designed to give many years reliable service under normal operating and

storage conditions.

Regular calibration checks over the life of the thickness gauges are a requirement of quality management

procedures e.g. ISO 9000 and other standards. For checks and certification contact Elcometer or your local

supplier.
