PUK 401 is a two component, cold applied, chemically curing, self leveling type, polyurethane based, coal tar modified.
PUK 401 is a two component, cold applied, chemically curing, self leveling type, polyurethane based, coal tar modified,
low modulus elastomeric material with high abrasion resistance and adhesion; suitable for heavy traffic conditions;
resistant to jet fuels, hydraulic fluids and oils and dynamic movements. It is resistant to UV radiation. PUK 401 is produced
especially for runways, park areas, terminals and ramps, cargo fields and roads at airports. It is suitable for all joints and
cracks where high elasticity is desired. Provides advanced adhesion and elasticity in asphalt - concrete joints and asphalt
- asphalt joints. It is suitable for all kinds of horizontal outdoor joints.

It is cold applied.It cures chemically.It is self leveling.It has high abrasion resistance and adhesion.It is resistant to dynamic
movements.It is ideal for all joint and crack repairs where high elasticity is desired.Provides advanced adhesion and
elasticity in asphalt - concrete joints and asphalt - asphalt joints.It is resistant to jet fuels, oils, diluted acids and bases,
various chemicals.It is fully resistant to UV radiation.Faster or slower curing can be provided depending on the customer
Joint width must not be less than four times the expected movement or 6 mm. Up to 15 mm width, joint sealant depth
must be equal to the width. Between 15 and 30 mm joint widths, sealant depth must be equal to 80% of the width. For
wider joints, sealant depth must be set to 30 mm. For adjusting depth, backer material must be used inside the joint.
For localizing the cracks caused by contractions that may occur during and after curing at new concrete pavements, design
and sealing of the contraction joints left before cure or saw cut after cure are also important.
Joint surfaces must be clean and dry. Oil, grease, bitumen or sealant remains must be completely removed. Loose
materials on the joint walls must be removed; broken joint walls must be repaired. PUK 401 is affected from water before
curing like all other polyurethane materials. Therefore the joints must be dry and the sealant must not contact water until
chemical curing occurs.
PUK 401 consists of two components, namely A and B, and these are packed in proportional mixing ratios.
First the container of component A is opened and it is homogenized for 2 - 3 minutes, then all of component B is poured
onto component A and it is mixed via a low speed (100/500 rev/min) drill and a suitable paddle for 4 - 5 minutes. Longer
mixing times are required to obtain a homogeneous mixture in manual mixing (not recommended).During mixing the
mixer must be moved inside the container and it must be ensured that no air is trapped inside.
The amount that can be used within the pot life must be determined by considering the application place and the capacity
of the application apparatus. Mixed material must be used within its pot life. Solvents can not be used for thinning the
sealant at the end of its pot life. Material at the end of its pot life must not be used.In machine applications pot life is
important for the tip section where the components mix together. If the application is interrupted for any reason, that
section must be cleaned immediately. In hand applications prepared mixture is filled into a refillable type application
apparatus with piston (sealant gun - applicator). In both application types, a nozzle with a diameter enabling it to enter
into the joint must be fitted to the apparatus and while the sealant is applied this tip must be moved forward by sliding
over the backer material in the joint.It is recommended to tape both sides of the joint before starting application on joints
especially where the decorative look is important. In this manner material smeared outside of the joint during the application
is removed by pulling off the tape after the application.
The material must be kept in dry indoor
storages. Recommended storage
temperature is 10ºC - 25ºC. Stored in
these conditions, the shelf life is 12
