MOLSIEVE PURMOL™ 3ST POWDER exhibits the ability to adsorb small, polar molecules while excluding larger organic molecules. In practical applications, it serves as a highly effective moisture scavenger for a range of materials, including polyurethanes, zinc-rich primers, aluminum-pigmented coatings, and polysulfide systems. It is a synthetic zeolite in powdered form, characterized by a complex alkali aluminosilicate structure. This unique structure features open pores with precise and uniform sizes, enabling selective adsorption based on the molecular size and polarity of molecules.
