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 77 Pre-wash Hydrophilic emulsifier Rinsing Drying Developer
Conventional post-emulsion method diagram:
RC 77 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 77 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.
