Chlorinated solvent free version of Hylomar Aerograde PL32
Description
Hylomar Aerograde Ultra is a highly engineered, polyester-urethane based non-setting and non-
hardening gasketing compound, for use in the aeronautical industry. Hylomar Aerograde Ultra was
developed in response to requests from Rolls Royce - Aerospace Division for a chlorinated solvent
free version of Hylomar Aerograde. Aerograde Ultra can operate at temperatures between –50°C and
up to + 250°C.
The product carries the same Rolls Royce MSRR 9055 approval as the old Aerograde
product and OMAT numbers 4/46A (light version) and 4/47A (standard version).

Instructions for use
The joint faces should be clean and dry. Both faces should then be coated with a thin even film of the
product and the solvent allowed to evaporate, the components are then assembled. Since Hylomar
Aerograde Ultra is non-setting, once applied to the faces of the component, immediate assembly is
not required. Due to the nature of Hylomar Aerograde Ultra, re-torquing of assembled components
may be required.
For stud loading, torque to required figure, allow compound to settle for a few minutes, then re-torque.
Hylomar Aerograde Ultra can be removed from dismantled components by rubbing with a cloth
soaked in Acetone. No scraping is necessary.
Typical Applications
Hylomar Aerograde Ultra is resistant to air; turbine and piston engine combustion products; water;
glycol/water and methanol/water mixtures; petroleum and synthetic diester lubricating oils; gasolines
and kerosene fluids (both Avtur and Avcat) and fluorocarbon refrigerants.
It is harmless to joint face materials. Traces of volatiles produced at elevated temperatures do not
stain copper or silver; therefore, Hylomar Aerograde Ultra is suitable for joints and threads in close
proximity to switch mechanisms etc. It is equally suitable for use as a gasket dressing and for metal to
metal application.
