Purseal
Elastic Polyurethane Resin for Crack Sealing
PURSEAL is a low viscosity polyurethane injection
system based on a polyol component (Part A) and a
polymeric MDI (Part B). PURSEAL is used by
injecting into cracks of concrete structure as well as
cracks with water leakage. It forms an elastic sealing
and repair the cracks permanently. Once cured, the
result is an elastic, tough, chemical resistant resin.
Properties | Component A | Component B |
---|---|---|
Appearance | Yellowish liquid | Dark brown liquid |
Viscosity at 25 °C (cps) | 150-220 cps | 120-180 cps |
Specific gravity at 25 °C | 1.20 ± 0.1 | 1.05 ± 0.1 |
PACKING | 16 kg./ set. |
---|---|
Part A | 10 kg. / can. |
Part B | 6 kg. / can. |
Surface Preparation
• All surfaces must be free from oil, grease, dirt and poorly adhering matter. If water is
leaking in the cracks, stop leak with PURFOAM first.
Installing the packers
• Mark the packer positions and drill the holes, make sure they pass through the cracks.
Depth of drilled holes should be somewhere between center of structure, if possible.
• Place packers in the previously drilled holes. Tighten the packers with a wrench as
tight as necessary.
• In case PURFOAM is used in the application, the previously injected packers can be
used.
Mixing
• Measure part A and part B with typical ratio of 10:6. Mix them together using low
speed drill and paddle mixer for approximately 2 minutes until the color appeared
homogeneous.
Injection
• Pump mixed material through the injection port until evidence of material begins to
show on concrete surface. Inject from the bottom up. Wait for material rise up the
cracks to ensure entire cracks has been treated.
Cleaning up
• Tools and equipment must be cleaned immediately after use.
• Packers can be removed after the material harden (3-4 hours) and the holes should
be patched.
