Description

RC-65 Properties

RC-65 is a post emulsion fluorescent penetrant. It is a Type 1 Method B, C, and D Level 3 penetrant according to AMS 2644 and Level 4 according to ISO3542.2 intended for the search for fine surface defects. This product is great for penetrating considering its level of sensitivity. The low viscosity of this penetrant offers the assurance of lower penetrant consumption, rapid pre-rinsing which is time saving, and slower saturation of the emulsifier bath meaning there is little penetrant remaining to emulsify after the pre-wash. RC-65 is designed for the inspection of critical parts, turbines 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-65 -> Pre-wash -> Hydrophilic emulsifier -> Rinsing -> Drying -> Developer Conventional post-emulsion method diagram :
RC-65 -> 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 ; 140°F to 176°F) is suggested; do not use compressed air. Infrared lamps and/or air guns are not advisable.

Development :

Although RC 65 is self-developing, using a developer enhances indications.

Inspection :

Inspect parts under appropriate UV-A lighting (mini 1000 μW/cm2, if possible > 1500 μW/cm2) and dimmed visible light (less than 20 lux).
