Magnaglo® 14A Redi-Bath
Magnaglo® 14A Redi-Bath is a prepared liquid concentrate of 14A Fluorescent Powder, wetting agents, anti-foaming agents and long lasting rust inhibitors.
Magnaglo® 14A Redi-Bath is a prepared liquid solution of 14A Fluorescent Powder, water, conditioning agents, corrosion inhibitors and carbon dioxide propellant.
Magnaglo® 14A Redi-Bath is used to locate fine surface and slightly subsurface discontinuities such as: inclusions, seams, shrink cracks, tears, laps, flakes, welding defects, grinding cracks, quenching cracks and fatigue cracks.
Magnaglo® 14A Redi-Bath is a prepared liquid concentrate composed of 14A fluorescentpowder, wetting agents, antifoaming agents and long lasting rust inhibitors. This product is packaged as a liquid concentrate to be added to a water bath. The graduated plastic bottle holds 800 ml (27 fl. oz.), enough to make 10 gallons of water bath. The contents of the one gallon container make 47 gallons of water bath.

14A Redi-Bath: Caution: Do not mix this concentrate into carrier oil. Use in Water Bath only! When mixed according to instructions, the bath settling volume after 30 minutes is 0.15 to 0.25 ml. Shake the container well to suspend the settled 14A Magnaglo® particles. The bottle is purposely not quite filled when new, which make it easier and faster to attain uniform distribution of particles in the concentrate.
To prepare a 10 gallon Magnaglo® bath, simply pour the entire contents of the 27 oz. bottle into 10 gallons (38 L) of water while stirring or recirculating. The one gallon container of 14A Redi-Bath makes 47 gallons (178 L) of water bath. Rinse container with a little water and add to the bath. To prepare partial baths, refer to graduation marks on the side of containers. The recommended unit dose for one gallon of water is 80 ml. Mix continuously or allow the prepared bath to re-circulate for 5 minutes prior to use. Make sure that the suspension passes through the application nozzle in the final minute. Perform particle settling test.
METHOD OF APPLICATION:
14A Redi-Bath: Parts should be cleaned prior to testing to reduce bath contamination and to ensure a more desirable test surface. The bath must be continuously agitated when in use to ensure uniformity, as particles will settle out of suspension on standing.
Using the wet continuous method, the bath is applied to all surfaces of the part. The instant the bath stream is removed from the part the magnetizing current is applied. The indications will be formed during the current shot. If the bath is applied after the magnetizing shot, the force of the bath application may wash away indications.
Using the wet residual method,the pre-magnetized part (must be of high retentivity) is immersed in the bath and then removed and allowed to drain. The indications will be formed in the bath but background will be reduced during the drain. This method is generally less sensitive than the continuous method. The bath is also more susceptible to rapid particle depletion and contamination using this method.
POST INSPECTION CLEANING:
The parts must be properly demagnetized before cleaning to ensure ease of particle removal.
