1. Molykote® 111 Compound – what
the industry uses to avoid oil seal
leakages…
Molykote® 111 is a silicone compound used during the assembly of ‘O’ rings and oil seals to
prevent oil leakages due to degradation of ‘O’ rings and seals in harsh environments.
Once applied on ‘O’ rings and oil seals, it forms a protective barrier between the rubber and the
media (oil, fuels, hot water, dilute chemicals), and does not allow the rubber to become brittle. It
acts as a rubber lubricant and provides a better sealing effect.
Features Benefits
Resistant to most chemicals, oils, Long service life. Has to be applied
water, diluted acids and alkalis, only once at the time of assembly.
common gases, etc Provides better sealing effect.
Highly adhesive in nature Does not get washed away, thereby
protecting the rubber component for
long periods in service
Excellent rubber lubrication Extends oil seal life thereby reducing
downtime associated with changing
‘O’ rings and oil seals
FDA Approved Can be used on where in contact with
potable water and incidental food
contact is likely.
Applications Areas
Lubrication for rubber seals and ‘O’ rings to prevent degradation and oil leakages, sealant for
vacuum and pressure systems, chemical barrier coating, as an anti-stick sealant for transformer
gaskets, O – ring lubricant in binocular and telescopes, Sealant for outdoor equipment, including
shipboard applications, subject to washing and harsh environments, etc.
Used only at the time of assembly by liberally spreading over the sealing element to extend seal
life.
Chemical Resistance
Resistant to the following: cold and hold water, 40% nitric acid, concentrated sulfuric acid,
glycol, glycerine, lubricating oils, butane, refinery gas, natural gas, liquid ammonia, sulphur
dioxide, etc.
Pack Sizes: 1 kg and 25 kg packs. 100 grams tubes available for trials.
