Non Destructive Testing // Penetrant Cleaners & Removers

DUBL-CHEK ER-85
Method B Emulsifier
  • Low to near zero background for assured indication visibility
  • Long material tank life due to formula stability and non-volatility
  • Minimizes the risk of over – emulsification
  • Clean, odorless product, vapor free atmosphere

Description

ER-85 is a lipophilic emulsifier used in the inspection penetrant process to remove excess surface penetrant. ER-85 is a Method B emulsifier. It does not require a pre-wash step and is used at full strength. It meets the requirements for low sulphur, low halogen, and low sodium.

Directions

1. Application: Apply non-water washable penetrant only to clean, dry surfaces by spraying, flowing, brushing or dipping.
2. Dwell Time: A 10-minute dwell time is suggested, although in many cases five minutes will suffice. When particularly tight cracks are suspected, or the part is especially critical, the dwell time may be extended to 30 minutes or longer. Allow the penetrant to drain from the part surface back into the penetrant tank to conserve material.
3. Removal: Use the appropriate washing method to remove the excess penetrant from the surface.
a. Emulsification: Following the dwell, dip the part into undiluted lipophilic emulsifier. Remove the part and allow the excess emulsifier to drain back into the tank. Parts with rough surfaces require longer drain times.
b. Rinse: Use a coarse plain water spray to remove all traces of the emulsified penetrant.
4. Drying: A re-circulating oven set no higher than 160F (71C) is suggested. Leave the part in the oven just long enough to evaporate surface moisture. Drying is improved by using pressurized air to disperse and remove as much excess water as possible before placing the part into the oven. Drying is improved by using pressurized air to disperse and remove as much excess water as possible before placing the part into the oven.
5. Developing: Apply the developer by cloud, dusting, spray or dip using the appropriate developer. Flaw marks are visible under appropriate lighting almost immediately but allow sufficient developing time to enhance the flaw visibility.
6. Inspection: Inspect parts under appropriate light.
