Single-component Polyurethane Sealant
1. Single-component without mixing
2. Good elasticity, high activity
3. Waterproof seal, can be soak for a long time
4. The strong cohesive force, contaminate the base material
5. Widely usecan be colored
Scope of application
Suitable for all kinds of weather resistance of curtain wall
caulkingConcrete expansion sealThe seal around the door, windowAll kinds of metal, stone, wood, ceramic, most of the material such
as plastic, rubber, tile Or a combination of the above material is
waterproof, soundproof sealing caulking; The place such as air
conditioning pipe sound insulation, heat preservation seal. Do not apply to the structural sealant and soaking in swimming
Method of application
Key points of design
1.The seams meet the precondition of telescopic allowance of base
material, the minimum joint width is 5 mm.
2.The depth of range shall be equal to 1/2 of width to width ,
suggest seam's depth not less than 5 mm; For below about 10 mm
width seam , Suggest to be 80% to 100% of width.
3. In order to ensure the sealant to achieve the design activity in
the service period, should use the backing or force protection band.
4. When designing the joint, should take into account activity
level of the base material and expansion of sealant.
Base plane treatment
Base material surface should be dry, without laitance, dust, or
contaminants. Metal surface should be no oil stain, rusty spot,
color chip which is easy to fall off. Pouring concrete after airing
dry for 28 days. After the rain, outdoor construction need to be
dry for 2 ~ 3 days; The moisture content of base material should be
lower than 9%.
Use brush to remove pollutants, let the juncture place to achieve
the above processing requirements. Backing should choose lever closed groove polyethylene foam
(diameter is about 1.25 times of the width).If the depth's of the seam is less than the above requirements, it
can use polyethylene force protection band to replace.When put into the backing should avoid too loose or too close,
putting backing into level position .You can use paper tape for beautiful , stick the adhesive tape on
both sides of the seams, the tape edge must be aligned with seams. Cut the required size
with 45 °, put the sealant into corresponding glue guns, squeeze
the sealant evenly along the joint, the sealant should fill the
seams full and spill over a little, avoid producing space in the
Using the length (m) of each glue（600ml）
