Chloroprene rubber SN243 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-30 of the Unites State.
∇ Fast rate of crystallization and stronger cohesion;
∀ Slightly higher viscosity than SN242;
þ Can be dissolved in toluene or mixed solvents;
Σ Better solubility and uniformity than CR244 and good storage stability;
Ý Adhesive cements prepared by SN243 is light in color and high bonding strength, quick good grips, easy handling, the adhesion layer to keep a long time;
φ Good resistant to ozone, weather, oil, chemical corrosion and extension of the fine is not flammable;
ψ The same applied properties as Dupont AD-30 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||54 – 75|
|Mass fraction of volatiles, wt. %||≤ 1.3|
|Mass fraction of ash, wt. %||≤ 1.0|
Dupont, American: AD-30
Denka, Japan: A-100
Lanxess, Germany: 330
SN243, which is a basic raw material of preparing adhesive cements, can be used alone or combination with other types, preparing adhesive where a very higher tack is required. Adhesive is suitable for bonding of the shoe industry, rubber leather, wood, metal and construction materials.
