Fast Curing Construction PU Adhesive Sealant For Concrete / Roof /
-single component, wet solidifying, convenient to operate;
-good sag resistance, not to flow in the construction of vertical
-noncorrosive to base material, no penetration pollution;
I-Like Construction PU Sealant is a single component moisture cure
sealant that can be used for exterior and interior caulking. Ideal
for use in roofing, siding and window installation. The cured
sealant adheres well to most common substrates such as masonry,
concrete, glass and aluminum without priming.
-One-Pack Polyurethane System
-Easy application and no problem with mixing because of one-packing
-Good elasticity and restoration prevents movement of substrate on
thermal change condition
-Even after vulcanization, has initial flexibility gives strong
resistance against the continuous restore and elongation.
-Decrease of construction cost and time.
-Extended use of various thermal range. (20-79°C)
1. Cleaning the surface:
take the appropriate amount of supported cleaner into clean and dry
special container(timely seal the original packing). Use the clean
absorbent cotton or other materials to dip the cleaner, clean up
the grease and dust on the to-be-bonded surface, then completely
dry(about 10 minutes, ranging with the temperature and humidity).
2. Brushing the primer:
completely shake up the primer, then take the appropriate amount of
primer into the special container(timely seal the original
packing). Brush a thin layer of primer on the cleaned surface with
the soft wool brusher, then completely dry(about 10 minutes,
ranging with the temperature and humidity).
3. Gelatinizing and Installation:
open the hole on the head end of aluminum canister using cone,
screw on the plastic nozzle, then open the mouth using sharp knife
on the nozzle with a certain size. If you use manual glue gun, you
should pry down the rear cover of aluminum canister; if you use
air-driven glue gun, you only open a small hole on the rear cover.
Then use the glue gun to uniformly spread the sealant onto the
to-be-bonded sections that have been brushed the primer by manual
or air-driven way.
For sausage-shaped soft packing: set the soft packing into the
600cc tubular glue gun, shear open the head end, install the
supported nozzle, then gelatinize by manual or air-driven way.
If necessary, you may adopt dot-form or bar-form gelatinizing
method, in 15 miunutes after gelatinizing, you should press the
to-be-installed workpiece onto the sealant and fix the position.
4. Cleaning up the surface:
The sealant spilled over from the aperture should be scraped
smoothly using scratch board or soap water. If careless, some
places are polluted by sealant, please remove them using
non-alcohol solvents such as gasoline as soon as possible. If the
sealant has been solidified, please use blade to cut or burnish.
-To do the experiment in advance is the necessary condition to
guarantee the excellent adhesiveness;
-After being opened, the cleaner must be used up in a day; or else,
it should be firmly sealed;
-Avoid contact with skin and eyes; if carelessly, please wash them
with a large amount of water and see the doctor;
-If the bonded part is heavy or needs moving, use the auxiliary
tool to fix the position during the solidifying
time(pressure-sensitive adhesive tape, locating block, etc.);
-The recommended use condition: temperature 15-35°C, humidity
40%-80%RH; keep the working condition completely ventilated;
-If you have any other problems, please contact with us.
