Description

Colpor 200PF is a two component cold applied pouring grade
joint sealant for pavement joints. It is flow applied into the joint
either directly from the can or using a sealant gun.
Colpor 200PF retains its movement accommodation of 25%
on butt joints throughout the extremes of temperature, it
does not harden in cold weather nor become excessively
soft, or pick up in hot conditions.
Colpor 200PF is resistant to jet blast and is suitable for concrete
runways and hardstandings.
Colpor 200PF is suitable for areas where fuel spillage is likely.
In trafficked areas the maximum expansion joint width should
not exceed 30 mm, wider joints are likely to suffer mechanical
damage. It is necessary to recess the level of the sealant 5 to
8 mm below the pavement surface, the depth is dependent on
the season and temperature at the time of sealing. Additional
protection for the joint aris can be provided by chamfering
the top edge.
The width/depth ratio of the Colpor 200PF seal should be
1:1 to 1½ :1 subject to a minimum 10 mm depth of sealant
(example, contraction joint: 15 mm wide x 13 mm depth;
expansion joint: 25 mm wide x 20 mm depth).
