Service life of wire ropes, armored cables, and umbilicals can be increased proportionally to the effectiveness of the lubricant applied and the amount of lubricant reaching the working parts.

Tuff Coat M Marine Lubricant Extends Service Life

Service life of wire ropes, armored cables, and umbilicals can be increased proportionally to the effectiveness of the lubricant applied and the amount of lubricant reaching the working parts.

What makes an effective lubricant?

A proper lubricant must have the following characteristics:

  • must reduce friction
  • must protect against corrosion
  • must be pliable and adhere to the wire when it is cold and not melt off when it is warm
  • must resist washout by water
  • must be safe to personnel and the environment

Features or performance characteristics of Tuff Coat M Marine Lubricant

  • Effective at reducing friction

Tuff Coat M has a very high lubricity. Synthetic oils are produced with better (perfect) molecules resulting in high lubricity characteristics as demonstrated in the synthetic oils used in today’s high performance cars and racing vehicles.

  • Superior protection against corrosion

Tuff Coat M forms an ionic bond to the wire. This ionic bond results in a tenacious film that displaces water from the metal surface. These properties were demonstrated in a Salt Spray Exposure Test (ASTM B117) in which a cable sample coated with Tuff Coat M and an un-coated control sample were exposed to salt spray for a period of 800 hours. On conclusion of the test the Tuff Coat M sample received a final rating of “8” (described as,” few isolated corroded areas, less than 0.1% of surface corroded) in accordance with the ASTM D610 grading scheme. The control sample received a final rating of “0” (described as,” approximately 100% of the surface corroded”).

  • Highly stable, staying pliable and adhering to the wire when it is cold and not melt off even at extreme temperatures.

Tuff Coat M is an extremely stable lubricant that retains its physical state and properties throughout a very wide temperature range. Thermal decomposition may occur at temperatures above 800º F. This extremely high temperature range makes it uniquely suitable for applications such as ROV umbilicals experiencing heating due to high power transfer and down-hole drilling applications where extreme temperatures are encountered.

  • Highly resistant to washout by water

Tuff Coat M is hydrophobic(lacking an affinity for water). Results of a Water Washout Test (ASTM D1264) performed at 38ºC and 78ºC were as follow:
@ 38ºC % loss was 0.19%
@ 78ºC % loss was 0.94%

  • Non-hazardous and inert substance that is safe to personnel and the environment

Tuff Coat M is non-hazardous which will not sheen the water. In a study to determine the toxicity of Tuff Coat M a 24-hour acute test was performed on Mysidopsis Bahia in accordance with U.S. Environmental Protection Agency (EPA/600/4-90/027F)(1993). The product passed the EPA requirements with a 100% survival rate of the M. Bahia in a 100% test concentration of TUFF COAT M.
