Bi-component Polyurethane sealant polyurethane Water swellable Sealant PU sealant

- Polyurethane Sealant PU Sealant Bicomponent Polyurethane Sealant PU Sealant is a one-component, solvent-free, water-swelling polyurethane-based amorphous sealant,Used to seal structural joints and reinforcement, pipes, lines around the leakage.With double seal water stop function,When water enters the seam,It will take advantage of the elasticity of the rubber (in order to stop the compression of water) and the expansion of the volume of water (in order to expand the pressure of water) to fill the gap, play a role in sealing.Bi-component polyurethane water-swelling water-stop sealant unique performance advantages, so that it has a very wide scope of application in practical engineering applications. No shape paste to ensure that it can be suitable for irregular base surface waterproof joints, and the construction is simple, easy to operate, is a variety of joints, especially between different materials, small space for the construction of high difficulty, humidity, Pile head and OTHER parts of the seal stop water. Contact with water, its expansion rate up to 220% of the original volume above. Construction can be vertical, not sagging; durability, excellent chemical stability.       Package Contents: 600ml/unit-package Package: 20 Unit-Packages in a carton box    Net Weight: 750g/unit-packages Executive Standard: JC/T483-2006                       Shelf Life: 12 months Carton Box Specification: 60*40*16cm   Bicomponent Polyurethane Sealant PU Sealant Features:
l. Adhesion: polysulfide sealant for cement, steel, glass, wood, natural stone, etc. have good adhesion. Should use low modulus and high elongation of polysulfide sealant, the adhesive strength ≥0.2Mpa, elongation ≥300% on the general construction and water conservancy projects.
2. Water resistance: polysulfide sealant effect of sea water, tap water, distilled water for stable, compared to seawater (salt) minimum weight change.
3.Aacid and alkaline can: polysulfide sealant resistant to strong acids, alkalis. But dilute mineral acid, alkali and various salts or stability.
4. Heat aging properties: polysulfide sealant heat aging performance is very good, long-term work under the conditions of a 40 ℃ ~ 120 ℃ of.
5. Radiation resistance Good: polysulfide sealant resistant r_ ray performance is very good.
6. Non-toxic: Although liquid polysulfide sealant little sulfur smelling odor, but gradually adsorbed by the filler after curing to create the polysulfide sealant to prevent environmental and health by the Chinese Academy of Medical Sciences Institute of Engineering tested L, D50> 20g / kg. According to the national standard toxicity grading is non-toxic level.
7.Aair tightness: polysulfide sealant is not only good elasticity, and its air-tightness in the elastic sealant is the best. Now second only to hot melt butyl rubber known in all kinds of plastic.     Bicomponent Polysulfide Sealant PU Sealant Delivery and StorageTips: ♦ Transport should be to prevent the sun and rain, impact, compression packing. ♦ Product in a dry, ventilated, cool place, storage temperature of not more than 27degrees. ♦ From the date of manufacture, shelf life of not less than 6 months.
