3A molecular sieve activated powder hydrated zeolite sodium A powder as moisture scavenger for plastic and coating systems
Activated Molecular Sieve 3A Powder is dehydrated synthetic powder molecular sieve. It is a highly effective moisture scavenger for plastic and coating systems. Due to its small pore openings Activated Molecular Sieve 3A Powder adsorbs practically only water. Typical areas of application are two-component polyurethane systems, moisture-curable polyurethanes, metallic pigment coatings, polysulfide and silicone systems, and as cosmetic ingredient.
