SYLOSIV® A 3 is a micronized, highly porous, crystalline aluminosilicate (also called molecular sieve) with pore openings of approximately 3 Å. It is a highly effective moisture scavenger for plastic and coating systems where even traces of water may create problems. Due to its small pore openings SYLOSIV® A 3 Molecular Sieve Powder adsorbs practically only water. Typical areas of application are twocomponent polyurethane systems, moisture-curable polyurethanes, metallic pigment coatings, polysulfide and silicone systems, and as cosmetic ingredient.
