IPCOTE - IP9182
IP CODE NUMBER: IP9182
PRODUCT DESCRIPTION
IP9182 is the latest development to the Ipcote range of sacrificial aluminium, corrosion resistant coatings designed for use in challenging environments such as aero engine and marine situations.
In a world where environmental and health & safety issues are becoming more important daily the reduction in the use of chrome and its derivatives is a major issue. IP9182 low chrome Ipcote shows a reduction of approximately 80% of hexavalent chrome over other typical sacrificial coatings.
Normally spray applied, Ipcote is used, for example, on turbine blades, rotors, shafts and landing gear to protect components from salt laden atmospheres, high temperature oxidation, chemicals and abrasives.
Used in a wide variety of applications, Ipcote provides corrosion and oxidation protection on iron, steel, heat treated stainless steel alloys, titanium and other metallic substrates at temperature up to 700°C (1300°F). Ipcote can also be super or vibro polished (RPS619) to enhance flow of air in aircraft engines where smooth surfaces enhance energy efficiency (see also Ipseal IP9184 and Smoothseal IP9444 and new chrome free seal coat). IP9182, when vibra polished, achieves a surface finish of 23 micro inches, similar to Sermetal W, Sermetal WFX achieves 17 micro inches, and IP9183/R1 polishes to 12 micro-inches!
This is only part of the Ipcote range. Apply for further information about our Seal coats, thin film versions, and touch ups.

In addition, work has now been carried out on Ipcote resistance to ASTM.B117 salt spray corrosion resistance on mild steel panels after lower temperature curing and bead peening: full results and photos are available on request.
APPLICATION
Appearance: When processed at high temperature (process A) 540-560°C (1000 – 1040°F) - dull matt grey - surface finish approx 70 micro inches.
When processed at 350°C (660°F) (process B) and bead peened - shiny bright aluminium similar to metal. Surface finish approx 70 micro inches. Often over coated with Ipseal for smoothness (see Ipseal IP9184) and to create a non-conductive barrier.
20 microns per coat ± 5 microns (0.8 thou ± 0.2)
Normally 2 coats per application giving 45-50 microns (0.8 thou - 2 thou)
Coverage - 7 square metres per litre at 25 microns (1 thou)
We also have experience of super polishing the material which can give finishes of 20 micro inches. This appears like highly polished aluminium (less than 20 microinches) such that reflections are visible (RPS 619).
