Instructions for Use (Spray Application)

N/A Mixing ratio by weight - Base 100
Mixing ratio by volume - Base 2 V
Mixing ratio by weight - Hardener / Catalyst 43
Mixing ratio by volume - Hardener / Catalyst 1 V
Mixing ratio by weight - Water 110 to 150
Mixing ratio by volume - Water 3 V to 4 V

Mixing Procedure
Ideally, the unmixed products should be stored between 18ºC (64ºF) and 25ºC (77ºF) for 24 hours before use.
The F70-A base should be mixed for 10 minutes in a pneumatic or oscillating mixer before use.
Mix the base and the hardener until the mixture is homogenous before adding demineralized water in two stages.
The mixture must be made at a temperature between 15ºC (59ºF) and 35ºC (95ºF).
Sieve the paint through a 80-150 µm (3.1-6.0 mils) filter.
Never add additional water once the paint mixture has been made..

Pot Life - 8 hours (dilution 4 V)

Note
The pot life depends on the dilution ratio.
The paint viscosity may vary depending on the temperature and increase over the pot life.
The water used to dilute the paint should be demineralised.
Depending on the material used and the application temperature, the dilution may vary between 3 V and 4 V of demineralised water.
A 3 V dilution of demineralised water is recommended for the white tints application.

Viscosities mentioned above are corresponding to the recommended range of viscosity to ensure compliant application. The range of dilution must be
used to adjust viscosity to reach the recommended one.
Water based paints show a thixotropic behaviour. This implies that efflux time can vary according different parameters such as: type of mixing, mixing
quantity, dilution, temperature, time between mixing and viscosity measurement

Instructions for Use (Brush Application)

N/A Mixing ratio by weight - Base 100
Mixing ratio by volume - Base 2 V
Mixing ratio by weight - Hardener / Catalyst 42
Mixing ratio by volume - Hardener / Catalyst 1 V
Mixing ratio by weight - Water 0 V or from 35 to 50
Mixing ratio by volume - Water0 V or of 1 V in 1.5

Mixing Procedure
Remove the safety ring and press down on the cap to release the F70-A hardener. Shake the container for approximately 1 minute. Remove the cap to be able to apply the F70-A topcoat with a suitable brush. If the material after shaking of 1min is not homogenious please use a stick for futher mixing (around 1 min) until the material is homogen.
Do not hermetically close TUK after mixing base and hardener.

Induction Time - In case of dilution, wait 3 minutes before adding demineralized water

Pot Life - 2 hours undiluted

Note - Spray with dry, oil-free air.

Defects and Corrections

Defects and Corrections

N/A In the event of a defect, contact your Quality Department. In case of low thickness:
Apply a thin coat of F70-A to achieve the desired thickness. If the above recommended recoating time is exceeded, reactivate with a Scotch-Brite type.

In case of thick coats:
Contact you Quality Department.

If there are micro-bubbles, running, rejects or numerous inclusions:
Reactivate the surface using an abrasive paper (grade 220 to 320), remove the dust then clean the surface using an approved cleaning product. Apply a
thin coat of F70-A to achieve the required thickness.

In case of significant defects:
Remove the F70-A primer with an approved chemical paint remover or make a selective stripping to the P60-A primer. A surface treatment and the P60-
A primer application sould be done once again in case the substrate is exposed.
