PURMOL™ adsorbents are synthetic zeolites in powder form with a complex alkali aluminosilicate structure. This structure is very open in nature and contains pores of a regular and precisely defined size. This allows for a selective adsorption of molecules based on molecular size and polarity. PURMOL™ adsorbs small, polar molecules, while excluding large organic molecules. In practice, PURMOL™ adsorbs water, but not solvents, resins, etc. PURMOL™ is an excellent moisture scavenger for polyurethanes, zinc rich primers, aluminum-pigmented coatings, and polysulfide systems

- Product Uses
PURMOL™ 3ST is recommended for use with high quality coatings. In general, we recommend the addition of 2.5% - 5% PURMOL™ powder to the polyol component. This must be stirred thoroughly for a minimum of two hours to allow the PURMOL™ to adsorb all the water before addition of the isocyanate.
