Introduction

Chloroprene rubber SN244 is high bond strength, it is obtained by mercaptan modified and Chloroprene monomer by emulsion polymerization with high rate of crystallization.

It can be seen as equivalent to Dupont AD-40 of the United States.

Characteristics

1.Fast rate of crystallization and stronger cohesion;

2.The highest viscosity among the SN24- series;

3.Compared with CR244, has better solubility and uniformity;

4.Adhesive cements prepared by SN244 is light in color and storage stability;

5. Excellent bonding strength, quick grips, easy handling, the adhesion layer to keep a long time, can be dissolved in toluene or mixed solvents;

6.Good resistant to ozone, weather, oil, chemical corrosion and extension of the fine is not flammable;

7.The same applied properties as Dupont AD-40 of the United States.

Appearance

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

Application

SN244, 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.
