Chloroprene rubber SN244 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-40 of the United States.
∞ Fast rate of crystallization and stronger cohesion;
Ω The highest viscosity among the SN24- series;
∇ Compared with CR244, has better solubility and uniformity;
∀ Adhesive cements prepared by SN244 is light in color and storage stability;
Ø Excellent bonding strength, quick grips, easy handling, the adhesion layer to keep a long time, can be dissolved in toluene or mixed solvents;
λ Good resistant to ozone, weather, oil, chemical corrosion and extension of the fine is not flammable;
Δ The same applied properties as Dupont AD-40 of the United States.
White or light yellow chips, with talcum as a release agent, no mechanical impurities.
|Broodfield solution viscosity, 5% toluene solution, 25 ºC, mPa.s||76 – 115|
|Mass fraction of volatiles, wt. %||≤ 1.3|
|Mass fraction of ash, wt. %||≤ 1.0|
Dupont, American: AD-40
