Smoothcoat - IP9442
IP CODE NUMBER: IP9183 & IP9183/R1
PRODUCT DESCRIPTION
This sacrificial aluminium product is the first in a range of corrosion resistant coatings
designed for use in challenging environments such as aero engine
and marine situations. 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). IP9183, 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!

There are several preferred methods of application depending on several factors, operating temperature, substrate etc. Please apply for application instructions.
This is only part of the Ipcote range. Apply for further information about our Seal coats, thin film versions, and touch ups.
APPLICATION
Appearance: When processed at high temperature (process A) 540-560°C (1000 – 1040°F) - dull matt grey - surface finish approx 70 micro inches.
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).
