Instructions for Use

Instructions for Use (Spray Application)

 N/A Mixing ratio by weight - Base 100
Mixing ratio by volume - Base 4 V
Mixing ratio by weight - Hardener / Catalyst 24
Mixing ratio by volume - Hardener / Catalyst 1 V

Mixing Procedure - Ideally, the unmixed products should be stored between 18ºC and 25ºC (64ºF and 77ºF) for 24 hours before use.
The P65-C2K should be mixed for 5 to 10 minutes in a pneumatic or oscillating mixer before use.
Mix the base and the hardener until the mixture is homogeneous. The mixing must be made at a temperature between 15ºC (59ºF) and 35ºC (95ºF).
Sieve the paint through a 120-150 µm (4.5-6.0 mils) filter.

Induction Time - None

Spraying viscosity at 20ºC / 68ºF (Zahn 2 Cup) - 18 to 25s

Pot Life - 4 hours

Note
The paint viscosity may vary depending on the temperature and increase over the pot life.
Viscosities mentioned above are corresponding to the recommended range of viscosity to ensure compliant application. The range of dilution must be used to adjust

Instructions for Use (Brush Application)

 N/A Mixing ratio by weight - Base 100
Mixing ratio by volume - Base 4 V
Mixing ratio by weight - Hardener / Catalyst 24
Mixing ratio by volume - Hardener / Catalyst 1 V

Mixing Procedure - Mix the base and hardener in proportions indicated above until the mixture is completely homogeneous.

Induction Time - None

Pot Life - 4 hours

Note for Drying Times

 N/A Drying times have been determined using test pieces of 1 mm thickness, with a 20 µm (0.8 mils) dry film.
Before accelerated drying = 70ºC (158ºF), let it flash off for at least 15 minutes at room temperature.
Parts whose drying was forced must cool down to below 35 ºC (95ºF) before proceeding to the next step. To recoat P65-C2K primer with another product/primer, contact us.
For the P65-C2K primer infrared drying, contact us.
Drying time and temperature (evaporation and curing) are given for information only and may vary depending on humidity, the shape, the nature of the workpiece and the thickness of the paint.

Defects and Corrections

Defects and Corrections

 N/A In the event of a defect, contact your Quality Department.

For a dry thickness < 15µm (0.6 mils): Apply a thin layer to obtain the right thickness. If the recoating time is exceeded, reactivate with a Scotch-Brite type® A.

If there are micro-bubbles, running, rejects or numerous inclusions: Reactivate slightly, using an abrasive paper grade P240 or P320.
Remove dust using a suitable cloth and apply a thin coat of primer, as described above.
