Thioflex 600 is a multi-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 surfaces including
primed concrete, glass, aluminium and stainless steel.
Thioflex 600 is available in gun and pouring grades. The gun
grade is ideal for general application. It is packed in ready
to mix, 2.5 litre & 4 litre tins containing the base and curing
agent in the correct proportions. The pouring grade for joints
in horizontal surfaces is supplied in 4 litre & 5 litre packs
with the base and curing agent in separate tins. Both these
grades are available in Grey colour only.
For coloured sealants, Fosroc recommends the use of Nitoseal
MS300*‡, a single component high performance silyl
terminated polyether sealant, available in white, grey, black,
portland, rustic red and brown.
