GG 470
High performance, elastomeric joint sealant, (Gun Grade)
DESCRIPTION
MasterSeal GG 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 GG 470 is supplied in 2 packs, a total
of 3 litre sealed units for sealing horizontal and
vertical 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.
