Two-component polyurethane sealant
kg/piece
Density: .tons
Shelf life: months
Two-component polyurethane sealant is used in civil construction industry, Transportation industry, connection of building materials such as concrete prefabricated parts 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, large adjustable performance range, high mechanical strength, good adhesion, good elasticity, and excellent Restorability, 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:
Base layer treatment: The adhered surface must be neatly treated (portable cutting machine, grinding wheel, steel brush, etc.) to expose a 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:
1. The building must be kept dry, clean, and free of oil.
2. Before construction, primer liquid should be applied to the surface. After the surface is dry, wide protective tapes should be pasted on both sides of the gap to prevent excess polyurethane sealant from damaging the structure during construction. The surface is dirty.
3. Mix the white polyurethane sealant (component) in the barrel and the black curing agent (component B) in the bag thoroughly until there is no color difference. :B=:, You should do a small test before use.
4. Fill the mixed polyurethane building waterproof sealant sealant two-component polysulfide waterproof sealant
Ester sealant into the gap with a putty knife or glue extrusion gun and compact it. Then use a &c 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. (External drying time & hours, days
can be followed by watering test, and the weather performance can be fully achieved.)
6. The prepared polyurethane sealant should be used up within two hours, otherwise it will slowly solidify due to the paste This will cause construction difficulties and avoid waste.
