Features & Benefits

• Meets key international standards - see Product Certifications
• 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

Uses

• Particularly recommended for use in high-rise buildings and other applications where access for subsequent maintenance will be difficult and the risk of early movement failure must be minimised
• Also suitable for sealing joints in brickwork, retaining walls, basements and subways
• Pouring grade is recommended for initial sealing of expansion joints and stress relief joints in floors and sealing other horizontal surfaces

Product Certifications

• British Standard EN14188-2:2004. (Use of Fosroc Primer 7E required)
• U.S. Federal Specification TT-S-00227E November 1969 (amended 1970)
• DTp specification for Highway Works December 1991 series 1000 clause 1017
• ASTM C920-87: Type M, Grade NS, Class 25
• Thioflex 600 complies with LU Standard 1-085 ‘Fire Safety Performance of Materials’

Application Notes

• Gun Grade is packed in a ready to mix, 2.5 litre tin containing the base and curing agent in the correct proportions
• Pouring grade is supplied in 5 litre packs with the base and curing agent in separate tins
• May be applied to joints between 5 and 50 mm wide
• Application temperature 5°C to 50°C
• The use of a surface primer is always required on porous surfaces e.g Primer P7 or Primer 7E. On non-porous surfaces a primer is not normally required except where glass or glazed surfaces are to be permanently immersed in water
• Gun grade: Mix thoroughly using a slow speed drill (300 to 500 rpm) fitted with a Fosroc Sealant Mixing Paddle
• Immediately after mixing, load the sealant into a Fosroc ‘G’ Gun using the Follower Plate, and apply to the joint
• Pouring grade may be poured directly into horizontal joints or for application to horizontal joints less than 15 mm wide loaded into a Fosroc ‘G’ Gun
• Clean equipment immediately after use with Fosroc Equipment Cleaner
• Coverage is dependant on size of joint. See Guide to Quantities in the Product Data Sheet

Limitations

• Over-painting of sealants is not recommended because of the inability of paint films to accept movement. However, if definitely required, trials should be carried out to determine compatibility
• Should not be used in direct contact with materials containing pitch or bitumen
• Not suitable for use in contact with potable water; Nitoseal MS600 should be used
• Flammability: Burns but does not readily support combustion
