HIGH TEMPERATURE DRY FILM LUBRICANT

IP Code No - PL181

OMAT No - 4/36

Product Description -

Dry film lubricant resistant to corrosive environments, skydrol, lubricants, fuels and operating temperatures of up to 700°C (1300°F), in areas of fretting and anti galling. Used for example on the marine RB211 and Rolls Westinghouse WR21. Protecting an internal satellite bush running at 500-550°C (930-1020°F), it is used at the turbine end in a variable geometry area to reduce friction.

This material has been under test by NEI and National Power on massive nuts and bolts used in steam boxes as an alternative to high temperature thread paste graphite, etc as an anti galling material. They have currently undergone testing for a 1000 hours at 600°C (1110°F) with a water soak at 80°C (175°F) for a further 100 hours, with the result at PL181 appears to be the best material for a release agent in this area. Compared with 8 or 9 alternatives, including high temperature greases, PL181 came out the best and is currently undergoing a second application and test to the same exacting standards to establish whether bolts used, can be reused after application of this material The bolts were torqued up to 0.1% and then the bolts were checked for ease of release by measuring their release strain.

MSRR 9200 OMAT 4/36 RR Code 132499 Complies with Def Stan 91-19

Performance -

Tested for resistance to MSRR 9200 which includes:

  • Dry oxidising heat at 700°C (1290°C)
  • Skydrol at 70°C (155°F) 3 hours
  • Rubbing wear test 100,000 rubs in 1 hour under 1.25 lbs pressure at 400, 500, 600 and 700°C
  • 1000 hours at 600°C (1110°F)
  • 100 hours at 80°C (175°F) in water

Application -

Object should be abrasive blasted, dry and grease free. Apply to substrate (Steel to MSRR 6504) by spray. Air dry for a minimum of 30 minutes, stove for 1 hour at 150°C (300°F). Wash equipment with water, heating the part to 50°C improves the quality of the coating. Ask for RPS 661/7.
