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
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™ 4ST to adsorb all the water before addition of the isocyanate. With metal dust coatings we recommend the addition of 0.5% - 2% PURMOL™ 4ST powder.

- Other Hazards
- All potential hazards are caused by the products's property to adsorb water. Dried product can dehydrate humid body parts (eyes, mucus membranes, lungs) or irritate them by the heat generated by the adsorption, the latter also applies to wetted or sweaty skin. The product saturated with water has no dangerous properties other than mechanical irritation by powder or small particles.
