ZJ-900
MS sealant for industrial use

ZJ-900 universal MS sealant is a high-quality, single component, paintable, and pollution resistant neutral modified sealant with good bonding performance. It reacts with moisture in the air and solidifies to form an elastomer with excellent properties such as high strength, aging resistance, vibration fatigue resistance, and low temperature corrosion resistance. JS-900 universal type can be generally used for building wall and cover plate sealing, LC plate, frame joint (inside and outside), window seal (inside and outside) waterproof joint (inside and outside), water storage and drainage structure joint, retaining wall and road separation joint, general civil construction project expansion joint, indoor decoration sealing, etc.

Operation and Safety
  • Coloring performance
  • This product can be colored using traditional methods after surface drying, including epoxy resin and acrylic acid coatings. Coatings containing high solvent components such as glossy enamel or high oil based coatings can cause the adhesive surface to become soft.
  • In order to achieve the best appearance and performance, the coating must be close to the tensile strength of this product. For areas with adhesive thickness less than 3mm, coloring can be carried out after 24 hours. For thicknesses greater than 3mm, coloring can be carried out after 48 hours.
  • Technical Services
  • The company provides comprehensive technical support to customers.
  • Health and Safety Instructions
  • Do not contact uncured sealant products with food or cosmetics; Uncured sealant should not come into contact with the skin for a long time;
