& nbsp; & nbsp; Introduction to Polyurethane MS Assembled Sealing Adhesive

  & nbsp; & nbsp; Polyurethane MS assembly sealant is a single component polyurethane sealant based on moisture curing PU prepolymer. It is a special sealant suitable for sealing car windshields and bodies. It has outstanding shock absorption function, outstanding elongation and outstanding resilience. It is suitable for various porous and non porous materials. It is a high-performance universal elastic sealant.

  & nbsp; & nbsp; Characteristics of polyurethane MS assembly sealant

  & nbsp; & nbsp; . High end black exterior, scratch resistant

  & nbsp; & nbsp; . Good thixotropy, no sagging

  & nbsp; & nbsp; . Outstanding weather resistance and UV linearity of polyurethane MS prefabricated sealant

  & nbsp; & nbsp; . Excellent antibacterial and anti mold properties

  & nbsp; & nbsp; . Outstanding elasticity, tear resistance, and excellent mechanical function

  & nbsp; & nbsp; . Strong adhesion, especially suitable for glass and paint

  & nbsp; & nbsp; . Polyurethane MS prefabricated sealant has no odor, ultra-low volatility, no shrinkage, and is safe to use
  & nbsp; & nbsp; . After curing, the shrinkage rate is extremely low, the shape is good, there are no dents, and the bonding area is flat


  & nbsp; & nbsp; Application field of polyurethane MS prefabricated sealant

In industries such as passenger cars, construction vehicles, and electric sedans, it is used to fill and seal gaps between glass and sheet metal, as well as between sheet metal and sheet metal< br />
  & nbsp; & nbsp; Application skills of polyurethane MS assembly sealant



  & nbsp; & nbsp; It is necessary to clean, dry, and free of grease before bonding< br />
  & nbsp; & nbsp; Base materials that may leak oil are not suitable for direct application of sealant< br />
  & nbsp; & nbsp; For rusted or corroded metal surfaces (such as aluminum oxide, copper and iron oxide rust surfaces), to ensure adhesion, it is necessary to wipe off the rust floating on the surface before applying glue< br />


  & nbsp; & nbsp; Due to differences in construction environment, construction methods, and materials, pre testing is required before using polyurethane MS prefabricated sealant to ensure bonding function< br />
The optimal coating temperature is 15-40 ℃. When the ambient temperature is low, the resistance to extrusion increases, so glue can be used after heating.
