Polyseal PS is a two component, low modulus, chemically curing polysulphide joint sealant developed specifically for dynamic joints. It is based on a liquid polysulphide polymer which when mixed with the hardener, cures to form a tough rubber like seal. Polyseal PS exhibits excellent adhesion to most surfaces and has good resistance to most chemicals & weathering conditions. Polyseal PS is available in both gun and pouring grades. The gun grade is suitable for vertical or horizontal application. It is available in a ready to mix, 2.5 litre tin containing all components in correct proportions. The pouring grade is suitable for horizontal application and is available in 4 litre packs with base and curing agent in separate tins.
