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.
High performance, elastomeric joint sealant (Pouring Grade). 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.
Application
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.
Used for sealing horizontal joints where pronounced cyclical movement is expected and where the service conditions would be harsh for most common sealants.
