SN243

SN243

Introduction

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.

Characteristics

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.

Appearance
White or light yellow chips, with talcum as a release agent, no mechanical impurities.

Typical property

Item SN243
Broodfield solution viscosity,  5% toluene solution, 25 ºC,  mPa.s 54 – 75
Mass fraction of volatiles,   wt. % ≤ 1.3

Comparable grades

Dupont, American:    AD-30

Denka, Japan:         A-100

Application :

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.
