Thioflex 600
Multi component, gun and pouring grade, polysulfide sealant.
Uses:
Sealing movement joints in building and civil engineering structures, including superstructures, floors, basements and subways.
Advantages:
- Meets key international standards
- Forms a tough, elastic, rubber-like seal
- Accommodates continuous and pronounced cyclic movement
- Excellent adhesion to most common substrates, including primed concrete, glass, aluminium and stainless steel
- High resistance to ageing reduces physical damage due to climatic extremes
Description:
Thioflex 600 is available in gun and pouring grades. The gun grade is ideal for general application. It is packed in a ready to mix, 2.5 litre tin containing the base and curing agent in the correct proportions. The pouring grade for joints in horizontal surfaces is supplied in 5 litre packs with the base and curing agent in separate tins.
Thioflex 600 is particularly recommended for use in highrise 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, basements and subways.
Thioflex 600 pouring grade is recommended for initial sealing of expansion joints and stress relief joints in floors and sealing other horizontal surfaces.
Design criteria:
Thioflex 600 may be applied to joints between 5 and 50 mm wide. Joints which are expected to experience cyclic movements should be designed to an optimum width : depth ratio 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 shouldbe designed in accordance with the recommendations of BS 6093.
The use of a surface primer is always required on porous surfaces. On non-porous surfaces a primer is not normally required except where glass or glazed surfaces are to be permanently immersed in water.
