Description:
Chloroprene rubber SN242 is high bond strength,it is obtained by mercaptan modified and Chloroprene monomer by emulsion polymerization with high rate of crystallization,for using a Nairit recipe and process technology.It can be seen as equivalent to Dupont AD-20 of the Unite States.
Chloroprene rubber SN242,which has a fast rate of crystallization and stronger cohesion,has a medium viscosity among the SN24-series and can be dissolved in toluene or mixed solvents,has better solubility and uniformity than CR244 and good storage stability.Preparing adhesive cements by SN242 is light in color and high bonding strength,quick good grips,easy handing,adhesion layer to keep a long time.It exhibits good resistant to ozone,weather,oil,chemical corrosion and extension of the fine is not flammable.SN242 can be divided into SN242A and SN242B,SN242A is closer to A90 and can be used as applicable grade of preparing grafted adhesive.SN242B is closer to AD-20,mainly preparing decoration adhesive and so on.
