Large expansion PU foam sealant is an one-component,
self-expanding,multipurpose polyurethane foam. This foam will
expand and cure
by moisture in the air. It is used for a wide range of building
applications. It is very good for filling and sealing with
excellent mounting capacities, high thermal and acoustical
insulation. Higher expansion rate than normal Pu foam.
CONSTRUCTION ADVICE:
1. Remove surface dust and oil before construction. Spray a little
water on the construction surface when the humidity is below 50
°C, otherwise the curing will be slow. 2. Shake the tank for one
minute before use. 3. Vertical gap construction from bottom to
top. 4. Please clean the foaming agent and the foaming agent gun
with a cleaning agent before the foam is cured. 5. The dry time
is about 5 minutes. It can be cut after 30 minutes. It is
recommended to cut after 1 hour, stabilize after 3-5 hours, and
fully
cure at 24 hours. 6. This product is not UV-resistant. It is
recommended to make a layer of shade or paint on the surface of the
gel to prevent direct light, thus extending the service life. 7.
When the temperature is lower than 50 °C, the tank should be
heated with 40-50C warm water to ensure the foam in the tank is
finished and the foaming multiple is increased.
PRECAUTIONS:
1. Please prepare for construction before construction, wear
gloves, wear overalls, and wear protective glasses if necessary.
Cover the surrounding objects with waste newspapers to prevent
contamination by the sprayed colloid. 2. If the foaming agent
touches the skin, please rinse it with soap and water in time. 3.
The construction site should have ventilation conditions, and
should not be close to the fire source, and should not smoke. 4.
After the product is cured, it has strong adhesiveness and is
permeable to the clothes fiber. Do not touch the clothes when
using. 5. The used tank is strictly prohibited from burning or
puncture. 6. It is strictly forbidden to store or transport
inverted or sideways (the valve will be blocked if the inversion
time
is too long).
