SURPREN TM SN245T

Introduction
Chloroprene rubber SN245T has high bond strength, it is obtained by mercaptan modified and Chloroprene monomer which is polymerized in emulsion with high rate of crystallization. It can be seen as an equivalent to DuPont soft AC of the United States and the same as Denka TA-85 of Japan.

Characteristics

l  A fast rate of crystallization and strong cohesion force;

l  Can be dissolved in toluene or mixed solvents, has better solubility and uniformity and storage stability;

l  Preparing adhesive cements by SN245T is light in color, it has excellent bond strength, quick grips, easy handling and the adhesion layer to keep a long time;

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

l  The same applied properties as DuPont soft AC of the United States and Denka TA-85 of Japan.

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