Polysulfide Sealant

Polysulfide sealant, used at the temperature of -40 to 110℃ with normal life up to 20 years, is amorphous material before solidifying, while it forms high elasticity of colloidal after solidifying. It features good construction performance, excellent water resistance, oil proof and chemical resistance. Besides, our product can be solidified at room temperature in control of speed of solidifying with no corrosion to building materials.

Polysulfide sealant has superior adhesion to most metal and nonmetal construction materials, such as metals, concrete, glass, ceramic, wood material, stone material, plastic and so on. It is also applicable to different fabricated construction panels, metal composite panels, profiled steel sheet, external concrete wall, brickwork, floor, porch, water reservoir, retaining wall, barn, drainage pipeline, subway and underground structures, roads, bridges, airport runway and so on for crack repair. Besides, polysulfide sealant can provide treatment of coating waterproofing and corrosion proofing, vibration-reduction, noise-isolation and reinforcement, etc.

Dosage and Packing
Dosage of polysulfide sealant changes with the actual requirements of engineering, and it is packed in 5.5 kg per team.

  • PCL Polycarboxylate Superplasticizer Concrete AdmixturePCL polycarboxylate superplasticizer concrete admixture features good stability especially at low temperature. Besides, the liquid concentration of our product can be diluted from 50% to 10% and then you can directly use the diluted product as pumping admixture of mixing plant.
  • FDN Naphthalene Sulfonate Formaldehyde Condensate Concrete AdmixtureCompared with UNF-5 type, FDN naphthalene sulfonate formaldehyde condensate concrete admixture has higher water reducing rate and fewer concrete slump loss, which can efficiently increase the concrete fluidity, reduce bleeding and segregation and then improve the workability of concrete.
