Elastomers (CASE)
Zeochem’s Purmol powders are excellent moisture scavengers for polyurethane coatings, adhesives, sealants and elastomers. Purmol adsorbents are synthetic zeolites in powder form with a complex alkali aluminosilicate structure. This structure is very open and contains pores of a regular and precisely defined size. This allows Zeochem Purmol powders to adsorb molecules selectively based on molecular size and polarity. In practice, Purmol powder adsorbs water, but not solvents, resins or pigments. Its powder form allows for easy incorporation.
The Purmol product line has a wide variety of uses. While many current applications are based on polyurethane and other plastics, Purmol powders can be used in numerous formulations where selective adsorption of small polar molecules is required within a liquid or solid medium. Its fine particle size ensures intimate mixing and excellent dispersion.
In each of the following applications, Purmol powder is a vital component of a top-quality formulation.
