Multi-component, gun and pouring grade,poly-sulphide sealantUsesSealing movement joints in building and civil engineering structures, including superstructures, reservoirs, floors, basements and subways
Design criteriaThioflex 600 may be applied to joints between 5 mm and 50 mm wide. Joints which are expected to experience cyclic movements should be designed to an optimum width: depthratio of 2:1, subject to the overriding recommended minimum sealant depths set out below:5 mm for metals, glass and other non-porous surfaces.10 mm for all porous surfaces. 20 mm for trafficked joints and those subject to hydrostatic pressures. To ensure that the sealant remains within its stated movement capacity (25% MAF), sealing slot widths should be designed in accordance with the recommendations of BS6093.The use of a surface primer is always required on porous surfaces. On non-porous surfaces a primer is not normally required except where joints are to be intermittently or permanently immersed in water.Example of a sealed movement joint in brickwork/block work is shown below:
Advantages
 Forms a tough, elastic, rubber-like seal.
 Accommodates continuous and pronounced cyclic movement.
Excellent adhesion to most common substrates.
High resistance to ageing reduces physical damage due to climatic extremes.

• DescriptionThioflex 600 multi-component joint sealant is based on a liquid polysulphide polymer, which when mixed and applied, cures to form a tough, rubber-like seal. The cured sealant exhibits excellent adhesion to most surfaces including primed concrete, glass, aluminium and stainless steel.Thioflex 600 is available in gun and pouring grades. Both grades are available in grey color only and supplied in 4 litre packs with the base and curing agent in separate tins. the gun grade is ideal for general application. The pouring grade for joints in horizontal surfaces.Thioflex 600 is particularly recommended for use in high rinse buildings and other applications where access for subsequent maintenance will be difficult and the risk of early movement failure must be minimised. It is also suitable for sealing joints in brickwork, retaining walls, reservoirs, basements and subways.Thioflex 600 pouring grade is recommended for sealing expansion joints and stress relief joints in floors or other horizontal surfaces.Standards compliance
