 SURPREN TM SN241

Introduction

Chloroprene rubber SN241 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-10 of the Unites State.

Characteristics

l  Fast rate of crystallization and stronger cohesion;

l  Lower viscosity among the SN24- series;

l  Compared with CR244, has better solubility and uniformity;

l  Adhesive cements prepared by SN241 is light in color and storage stability;

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

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

l  The same applied properties as Dupont AD-10 of the United States.

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