La description

Activated zeolite powder 3A is calcined synthetic zeolite power, after calcination, they lose most of moisture that they contain, so they can be used as adsorbent or desiccant directly in various application.

It is mainly used to remove moisture from polyurethane polymer systems; it deals with moisture problems without causing undue problems with shelf-life viscosity etc. Other types are used as additives for selective adsorption in defined polymer system or coating systems.

Typical Chemical Formula:
0.*5 K2O•0.*5 Na2O•Al2O3•2 SiO2•n H2O
