MAC 419 Water Based Mandrel Lubricant


Water based emulsion of a fluorochemical/ resin mixture. Produces a dry colorless film with a very low coefficient of friction and excellent lubricating properties. Provides excellent mandrel ejection on a variety of hose constructions and compounds.

Technical Data:

  • Color and appearance................Opaque-white to off-white emulsion
  • Dispersing medium.....................Water
  • Specific gravity............................1.02
  • Weight per gallon (lbs.)..............8.5

Application Method:

    MAC-419 is intended to be applied as received to clean, dry mandrel surfaces. Dilutions with water are possible depending upon the method of application and specific process characteristics of the hose compound and construction. Start with a clean, dry mandrel. All previously used mandrel lubricants and any compound residue should be removed by an appropriate method. McLube Mold Cleaner may be used. Application of MAC-419 can be accomplished by spraying, wiping, dipping, or flow coating a thin even film over the entire mandrel surface. For previously uncoated mandrels, two coats should be applied. Once the mandrel has cycled through the system once, only one coating need be applied. A coating of MAC-419 will dry in 10 to 30 minutes, depending upon the application technique used. Spraying the product will speed up the drying time. External heat sources can be used to further facilitate drying. Although it is recommended that MAC-419 be dry prior to tubing, some manufacturers are tubing immediately with no adverse effects. The specific processing characteristics of the tube compound and the hose constructions used will influence the need to dry the coating.

Safety and Handling:

    The Material Safety Data Sheet for MAC-419 should be reviewed prior to using the product. MAC-419 has a very low order of toxicity; however, good industrial hygiene practices should be observed. Safety glasses and gloves are recommended when using this product. Freezing of the product should also be avoided.
