RESIFLEX
200 is a cold applied two-part elastomeric pourable sealant for joints in
concrete paved areas, designed as easy to use and economical sealant. It is capable
of accommodating above average and severe climatic conditions, will not harden
in cold weather nor become excessively soft or pick up in hot conditions, as well
as possessing resistance to jet fuels, jet blast, oil, hydraulic fluid and a wide
range of chemicals. RESIFLEX 200 reduce maintenance costs because of its' long
service life.
* Permanently high elasticity
* Performs well over a broad
temperature range
* Low maintenance cost
* Jet fuel, oil, hydraulic fluid
and wide variety of solution resistance
* Self leveling, cold applied and easy
to use
* Excellent adhesion to common surfaces even pitch based substrates
*
Suitable for re-sealing joints previously sealed with pitch based hot poured sealants
USES
RESIFLEX
200 is used in horizontal joints such as:
* Motorways
* Runways, parking
bays and garages at airports
* Flooring and connection joints for over
ground
fuel storage depots and loading bays for fuel and oil
* Car parks and underground
garages
DESCRIPTION
RESIFLEX 200 is a very economical, cold applied,
two-component elastomeric sealant for sealing expansion joints in concrete paved
areas, under all climatic conditions. The greatest demands upon pavement joint
sealants are the result of joint movement caused by diurnal and seasonal temperature
changes. This movement rarely evenly distributed between the joints provided and
although the designed joint sealing dimensions and spacing may be within the theoretical
capacity of certain sealing materials, in practice this is substantially exceeded
in a significant number of joints. The elastic rubber-like nature of RESIFLEX
200 provides the extra capacity to accommodate these erratic movements with
far less risk of failure. These properties are retained throughout extremes of
climatic temperatures, unlike conventional hot-poured thermo-plastic pavement
sealants that become less flexible at lower temperatures, when joints open to
their maximum. Sealing with RESIFLEX 200 provides a greater level of sealing
efficiency over a much longer period, reducing maintenance costs and the interruption
of services.
JOINT CONFIGURATION
The expansion joint width is
normally designed by the width of expansion joint filler. RESIFLEX 200
will accommodate large continual cyclic movement. However, for optimum performance
joints should be designed to 25 % of material elasticity. RESIFLEX 200
should be sealed 5 - 8 mm. below the concrete pavement surface dependent on time
of the year and application temperature. The width/depth ratio of the RESIFLEX
200 should be 1:1 to 1.5:1 subject to a minimum 10 mm. depth of sealant.
