Hylomar® Aerograde PL32 is a highly engineered, polyester-urethane based non-setting and non-hardening gasketing compound, for use in the aeronautical industry. Hylomar Aerograde was developed in conjunction with Rolls Royce – Aerospace Division for sealing joints in jet turbine engines. Hylomar Aerograde can operate at temperatures from approximately -50°C to +250°C. (-58°F to 482°F).
Manufactured under licence from Rolls-Royce plc.
Features & Benefits
Non-setting jointing compound.
Temperature range -50°C to +250°C.
Resistant to fuels, oils, coolants and gases.
Easy to use.
Unlimited assembly time.
Easy to disassemble components sealed with Hylomar.
Use on metal to metal joint surfaces to replace conventional pre-formed gaskets.
Use as a gasket dressing to improve the sealing performance of the gasket and to assist gasket alignment during assembly.
Use as a non-curing thread sealant. Resists vibration
Hylomar Aerograde 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 some fluorocarbon refrigerants.
It is harmless to most joint face materials. Traces of volatiles produced at elevated temperatures do not stain copper or silver, therefore, Hylomar Aero Grade 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.
Hylomar Aerograde has been tested, approved and is in use by, National Power/ Powergen, MOD A.F.S. 147 D.T.D. 900/4586B, Rolls Royce MSRR 9055.
