Description

RC-50 Properties

RC-50 is a post-emulsion fluorescent penetrant. It is a type 1 Method, B, C, and D Level 2 penetrant according to AMS 2644 and ISO 3542-2 intended for the search for fine surface defects. This product has a low viscosity, an advantage when working by dipping as it guarantees low consumption when penetrating. The thin layer of penetrant remaining on the part to be emulsified, will require little emulsifier. It is a medium sensitivity fluorescent penetrant designed for inspection of critical parts, turbine blades, assemblies, and welds.

Instructions for use:

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-83A, ER-83B, ER-83C 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) 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 (mini 1000 μW/cm2,if possible >1500μW/cm2) and dimmed visible light (less than 20 lux).
