Advantages „ Forms a tough, elastic, rubber-like seal „ Accommodates continuous and pronounced cyclic movement (± 30%) „ Adheres to most common substrates „ High resistance to ageing reduces physical damage due to climatic extremes „ Easy mixing and application „ Safer lead free curing agent Description Thioflex 600 Gun Grade is a two-component joint sealant, 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 primed surfaces including concrete, glass, aluminium and stainless steel. Thioflex 600 Gun Grade is ideal for general applications and is packed in a ready-to-mix pack consisting of the base and curing agent in the correct proportions. Thioflex 600 Gun Grade is particularly recommended for use in civil structures, high rise 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. Technical Support Parchem offers a technical support package to specifiers and contractors as well as on-site technical advice from staff with experience in the construction industry. Design criteria Thioflex 600 Gun Grade 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 All joints where repeated movement occurs should be designed and spaced so that the total movement in tension or compression does not exceed 30% (i.e.: 60% total) of the joint width at time of sealing. The total movement in shear should not exceed 50% of joint width at the time of sealing where continuous cyclic movement is expected.
