H.V.G. Compound is
a stiff non-melting grease like Silicone Material. It maintains its
consistency over a wide temperature range of – 40o C
to 250o C. Its low
volatility, very low vapor pressure of the base, chemical resistance,
relatively constant consistency over a wide
temperature range sealing ability, make it an
ideal sealant for high vacuum and high pressure systems and sealant-cum-lubricant for chemical
processing equipment.
Applications
:
 As
a sealant and lubricant for
glass-ints and stop-cocks in high vacuum and high temperature systems as
well as in ordinary systems.
In
pressure lubricated plug valves, control valves and ceramic plug cocks.
In
valves of water – softener.
In
fire extinguishers to keep the valves
dependably operable for
long period
despite severe temperature conditions and corrosive atmosphere.
As
a sealant on floating telephone batteries.
Its
high tack may be taken advantage of, in holding rubber and other parts in position during
assembly of certain parts.
As
a release agent for epoxy, polystyrene, polyvinyl chloride, polyester
resins and other plastics. Normally it is used only
when common release agents including other silicone release
agent fail.
