Joint
Type
This joint is suitable for installation
in exterior applications in
floors, decks and walls forming
a watertight impenetrable seal
that is unaffected by road salts
and petroleum products. Its
elasticity will reject stones
and debris and will sustain
pedestrian traffic and repeated
loading from wheeled vehicles.
Applications
External floor to floor, floor
to wall and wall to wall applications
including podiums, pavements,
parking decks and ramps, airport
runways, and bridges including
steel deck bridges where positive
anchoring is not possible. React
1000 joints are also suitable
for use with potable and processed
water applications including
reservoirs and wastewater treatment
plants.
React 1000 will resist hydrostatic
pressure based upon the following
depths of
seal being used: |
React
1000 has excellent resistance
to a wide range of chemicals including
dilute acids and alkalis. For
specific applications, please

department for further assistance.

contains
a Hindered Amine Light Stabiliser
that inhibits the UV degradation of
the material. This stabiliser is regenerated
within the polymer and is not consumed
leading to the extreme longevity of
the joint. React 1000 does not use
carbon black pigmentation in its formulation
as this leads to heat generation and
accelerated shrinkage of polymers
that contain this compound. React
1000 joints have grooves along the
bond surfaces at 6mm to 12mm centres
and these are typically 3mm wide x
3mm deep and run the entire length
of the joint. These grooves increase
the surface area of the bond surfaces
and enhance adhesion to substrates.
React 1000 joints have a working movement
range of 60% compression and 30% extension
and are designed to be installed pre-compressed
by 25% into
structural gaps. Table 2 below shows
the width of the uncompressed joint,
associated gap width and +/- movement
capacity from this gap width. React
1000 joints supplied are sandy beige
in colour and special React 1000 flexible
coatings can be supplied which, when
applied, permit colour co-ordination
of the joint with other finishes without
compromising the joint's performance.
The physical and chemical properties
of this joint do not alter significantly
over the temperature range -70°C
to +70°C and all directional changes
in the joint must be carried out using
heat welding. This is accomplished
by placing the joint material ends
against a Teflon coated heating iron
at 176°C for 10 to 20 seconds.
The ends are then placed tightly together
and fusion bonded. Do not test the
weld until the material has completely
cooled and full strength achieved.
React 1000 Bonding Agent is supplied
and should be used to bond the joint
to the structure. This bonding agent
provides excellent adhesion in various
weather conditions and tests indicate
that the bond strength is greater
than the joint material strength which
is 0.8N/mm².
