Specification of MasterSeal PG 470 Sealant Polysulphides Based
DESCRIPTION
MasterSeal PG 470 is a high grade, Polysulphide based
sealant possessing outstanding resistance to
deterioration due to weathering, ozone, ultra-violet light
and attack by chemicals present in industrial
atmospheres. It has the ability to withstand repeated
cycles of compression and extension over a wide
temperature range, and has excellent adhesion
properties to all materials commonly employed in
building and construction work.
MasterSeal PG 470 is supplied as 3 liter units of base
and catalyst for sealing horizontal joints where
pronounced cyclical movement is expected and where
the service conditions would be harsh for most common
sealants. It is ideal for use in expansion joints in
reinforced concrete structures such as bridges,
reservoirs, water treatment works, sea walls and roads,
etc. It can also be used in floor joints subject to heavy
usage where a high resistance to damage is required.
