MANUFACTURER : SHERWIN (USA) / NDT-Europa (NL)

Post-emulsifiable ultra-high sensitivity fluorescent penetrant designed for inspection of critical parts, turbines blades, assemblies, welds. Type I, method B, C, D, level 4 according AMS 2644 and ISO 3452-2.

Companion products :

  • Lipophilic emulsifier ER-85
  • Hydrophilic emulsifier ER-83A, ER-83B, ER-83C
  • Developer D-90G, D-100, R60, D-106

Precautions

Transport / Handling :Refer to Material Safety Data Sheet (MSDS).Storage : Keep away from moistureTemperature range : 0°C à 50°C.Keep packaging closed after taking out some of theproduct

Directions for use

Parts cleaning : use appropriate process/products as per applicable specificationsApplication :By spraying (electrostatic, pneumatic), 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-washwithout pre-washPre-wash :RC-88 –> Pre-wash –> Hydrophilic emulsifier –> Rinsing –> Drying –> DeveloperConventional post-emulsion method diagram :RC-88 –> Hydrophilic or lipophilic emulsifier –> Rinsing –> Drying –> DeveloperThe 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 penetrantAir + 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-88 is self-developing, using a developer enhances indications.Inspection :Inspect parts under appropriate UV-A lighting (mini 1000 &mu-W/cm², if possible &ge-1500&mu-W/cm²) and dimmed visible light (less than 20 lux).
