Monel or aluminium tube draw lubricant
developed
Using a wax/grease type lubricant dissolved into methylenechloride as a dip coat lubricant on drawing aluminium or Monel tube is environmentally disadvantageous so an alternative was introduced.
John Neale has been working with a non-ferrous tube manufacturer to develop more environmentally acceptable tube lubricants for their process This company was using a wax/grease type lubricant dissolved into methylenechloride as a dip coat lubricant on their tube

Lubricant additives benefit SS tube drawing
Work to significantly enhance the lubrication of highly chlorinated tube drawing lubricants - and deep drawing - has lead to the discovery of additives which offer considerable performance benefits.
Lubricants smooth severe cold metal reductions
A range of lubricants can be applied as a coating for the most severe cold reductions in stainless steel alloy, and titanium and are suitable for the most arduous operations.
This lubricant works very effectively in terms of drawing performance on aluminium and monel tube.
However the use of a coating based on Methylene chloride gives them environmental and health and safety issues.
The use of Methylene chloride will require sophisticated containment equipment in the near future to meet the requirements of the solvents emission directive (SED).
After discussion with the company it was considered that a water based coating lubricant would be preferred as this overcomes all aspects of the SED and health and safety considerations.
John Neale used their significant experience in advanced tube drawing lubricants to develop a candidate water dilute-able lubricant to replace the Methylene chloride diluted coating.
This new coating required the following specifications.
1 - Water based (virtually zero VOC).
2 - Low hazard (no R40, R45, or more hazardous labeling).
3 - Highly effective.
4 - Removeable with a non-VOC solvent system, and water.
5 - Suitable for aluminium, copper, monel, brass, and various alloy tube.
6 - Low viscosity when diluted in water.
7 - Good wetting.
Trials conducted by the customer with this lubricant have shown it to have all the performance parameters required.
It performed better than the current lubricant on copper and at least as well on the other materials tested.
The customer is now progressing to consider the degreasing of this lubricant with state-of-the-art non-VOC solvent again supplied by John Neale.
Coating Lubricant PE(W) is an exciting addition to the coating pre-lubes available from John Nealefor severe tube drawing applications.
