INSTRUCTIONS:
Parts cleaning: use appropriate process/products as per
applicable specifications
Application: By spraying (electrostatic, pneumatic, aerosol),
using a brush, or by immersion.
Dwell time: 10 to 30 minutes, depending on applicable specs. If
dipping is used, allow the penetrant to drain
from the part surface back to the penetrant tank.
Removal: Two separate procedures apply:
-with pre-wash
-without pre-wash
Pre-wash:
RC 50 -> Pre-wash -> Hydrophilic
emulsifier -> Rinsing -> Drying -> Developer
Conventional post-emulsion method diagram :
RC 50 -> Hydrophilic or lipophilic emulsifier -> Rinsing -> Drying ->
Developer
The first process will save considerable
quantities of emulsifier. The emulsifier is applied by immersion or by
spraying (see technical datasheet ER 83 A or ER 85).
Rinsing off:
Use coarse plain water spray to remove all traces of emulsified
penetrant. Air + water spray gun is a good alternative.
Washing is carried out under UV-A radiation, so as to ensure that no
fluorescent background is left.
Drying:
A circulating oven (60 to 80°C ; 140°F to 176°F) is suggested; do not
use compressed air. Infrared lamps and/or air guns are not advisable.
Development:
Although RC 50 is self-developing, using a developer enhances
indications.
Inspection:
Inspect parts under appropriate UV-A lighting and dimmed visible light,
in accordance with ISO 3059.2001 standard.
HEALTH AND SAFETY: refer to MSDS.
