Density. tons
Shelf life months
Two-component polyurethane sealant is used in the civil construction industry, transportation industry, concrete prefabricated parts and other building materials connections and filling and sealing of construction joints. High-end roads, bridges, airstrips, underground pipelines, connection sealing at joints, and expansion and deformation joints in tunnels and buildings.
Product Features
Two-component polyurethane sealant has excellent wear resistance, low-temperature flexibility, wide adjustable performance range, and high mechanical strength. It has good adhesion, good elasticity, and excellent recovery properties, and can be suitable for dynamic joints, deformation joints, and expansion joints. It has good weather resistance, excellent oil resistance, biological aging resistance and low price.
Product construction method
The adhesive surface of the base layer must be neatly processed (portable cutting machine, grinding wheel, steel brush, etc.) to expose the solid structural layer on the glued surface . The joint surface must be completely dry, clean and frost-free. All dust and cement slurry on the surface must be cleaned and cleaned. The rust layer and protective paint on the metal surface also need to be removed. If the structure is not dry, it can be dried with a blowtorch.
Instructions for Use and Precautions
1. The building must be kept dry, clean, and free of oil.
2. Before construction, the primer liquid should be applied to the surface first. After the surface is dry, put wide protective tape on both sides of the gap to prevent construction. The excess polyurethane sealant in the box stains the surface of the structure
3. Stir the white polyurethane sealant (component) in the barrel and the black curing agent (component) in the bag thoroughly until
Until there is no color difference. , a small test should be done before use.
4. Fill the mixed polyurethane building waterproof sealant sealant two-component polysulfide waterproof sealant
ester sealant into the joint with a putty knife or glue extrusion gun. Fill it completely, and then use a wide putty knife to smooth the
glue.
5. Just remove the protective tape after applying the glue. Avoid exposure to water and rain within hours. (The surface drying time is hours, and the watering test can be done after 10 days, and the weather performance is fully achieved.) 6. The prepared polyurethane sealant should be used up within two hours, otherwise it will cause damage due to the paste. Slow curing will cause difficulty in construction and avoid waste.
