Sichuan two-component polyurethane sealant
Two-component polyurethane sealant is made of liquid rubber as the main base material, adding a variety of chemical additives through a special polymer material synthesis process. It is a novel non-toxic grade waterproof sealing material. The product has excellent water resistance, oil resistance, aging resistance and corrosion resistance. It is famous for its good sealing performance, strong adhesion, good elasticity and long service life. Scope of application of two-component polyurethane sealant
It is widely used for waterproof sealing of deformation joints such as concrete expansion, contraction and settlement in construction of municipal subway tunnels and water conservancy projects. Suitable for bonding cement, glue, forest, polyvinyl chloride, glass and other metals or non-metals. It is especially suitable for waterproof sealing of special deformation joints in various liquid storage structures such as sealing between joints in water plants, filter plates, and filter plates in sewage treatment plants.
Two-component polyurethane sealant product features
Adhesive polysulfide sealant has good adhesion to cement, steel, glass, wood, natural stone, etc. In general construction and water conservancy projects, polysulfide sealants with low modulus and high elongation should be used for their bonding strength and elongation.
Water-resistant polysulfide sealant is stable against seawater, tap water and distilled water, and has minimal weight change to salty seawater.
Acid and alkali resistance Polysulfide sealant is not resistant to concentrated acids and alkali. But it is stable to dilute inorganic acids and bases and various salts. Heat Aging Resistance Polysulfide sealant has very good heat aging properties and can work at a temperature of 1°C for a long time. Polysulfide sealant has good radiation resistance. Polysulfide sealant has very good radiation resistance.
Non-toxic Although liquid polysulfide sealant has a slight sulfur smell, it is gradually absorbed by the filler after curing. Our company's polysulfide sealant has been tested by the Institute of Environmental and Health Engineering, Chinese Academy of Preventive Medicine Sciences,/. It is classified as non-toxic according to the national toxicity classification standards.
Good air tightness Polysulfide sealant not only has good elasticity, but its air tightness is also the best among elastic sealants. Among the various glues currently known, butyl glue is second only to hot-melt butyl glue.
