 SURPREN TM SN240T

Introduction

Chloroprene rubber SN240T has high bond strength, it is obtained by mercaptan modified and Chloroprene monomer by emulsion polymerization with better sprayability and brushability and high rate of crystallization. It can be seen as an equivalent to DENKA A-30 of Japan.

Characteristics

l  Fast rate of crystallization and stronger cohesion;

l  The lowest viscosity among the SN24- series;

l  Better solubility and uniformity;

l  Adhesive cements prepared by SN240T is light in color and storage stability;

l  Excellent initial bond strength and bond strength, better spraying, smaller particles, non-splash, 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 DENKA A-30 of Japan.

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