Polyurethane Sealant for Construction Polyurethane Adhesive Sealant
with External walling curtain wall joints
Description
SV-311 is a one component polyurethane high modulus flexible
sealant formulated as reliable bonding adhesive and joint sealant
for construction industry, particularly where a higher modulus and
lower movement capacity are required for joints with low or medium
movement, e.g. connection joints between floor/stairs and wall,
connection joints between floor and machinery, seam sealing /
sealing of pipe ducts / ventilation systems, multipurpose joints in
metal and wood construction work.
Key Features
1. Non-sag consistency
2. Excellent adhesion to most common building materials
3. High tear strength
4. High tensile strength
5. Less fluid migration to porous material

PACKAGE:
- 300ml/310ml cartridge, 20 pcs/carton
- 600ml/400ml sausage, 20 pcs/carton
USES:
SV 311 PU Sealant is suitable for most building joints, including perimeter caulking of doors and windows.
- External walling,curtain wall joints.
- Skylights, smoke vents
- Joints in pre-cast panel.
- Other structural sealing for areas with structure movement
ClEANING:
Clean and dry all surfaces by removing foreign matter and
contaminants such as oil dust, grease, frost, water, dirt, old
sealants and any protective coating. Dust and loose particles
should be cleaned.
APPLICATION:
Minimum application temperature: 5°C.
SV 311 PU Sealant should be dispensed from either the cartridge or
sausage by means of a caulking gun. Pierce the membrane at the top
of the cartridge and screw on the nozzle. Cut nozzle to give the
required angle and bead size. Place the cartridge in an applicator
gun and squeeze the trigger. For sausages, a barrel gun is
required, clip the end of the sausage and place in barrel gun.
Screw end cap and nozzle on to barrel gun. Using the trigger
extrude the sealant, to stop depress using the catch plate. Apply
SV 311 PU Sealant in a continuous bead using enough pressure to
properly fill the gaps.

ADVICE:
- For common occasion, after cleaning out the surface with organic
solvent, this product can be used directly.
- Please construct by application instructions strictly, failure of
stickiness may be caused by any operation disobeying construction
techniques.
- This product is innocuous after curing completely, but before set,
please avoids contacting with eyes and skin. In case of eyes and
skin contact, wash immediately and thoroughly with soap and water.
See doctor immediately if it is serious.
