Coatings, Adhesives, Sealants and
Elastomers (CASE)
Better Moisture Control. Better Formulation Performance.
Even small amounts of moisture can create big problems in coatings, adhesives, sealants and elastomers—from unwanted reactions and processing issues to defects in the finished product.
Zeochem Purmol® molecular sieve powders help keep moisture under control. Designed to selectively adsorb water without adsorbing solvents, resins or pigments, Purmol products help protect your formulation and support consistent processing and performance.
Purmol adsorbents are synthetic zeolites with a highly porous structure and precisely defined pore sizes. This allows them to selectively adsorb small polar molecules such as water while leaving other formulation components largely unaffected.
Their fine powder form also makes Purmol products easy to incorporate and disperse throughout liquid and solid formulations.
Whether you’re working with polyurethane coatings, adhesives, sealants, elastomers or another moisture-sensitive formulation, Purmol products can help you manage unwanted moisture and get the performance you need.

13X
Type 13X offers enhanced adsorption properties and the ability to remove impurities too large to be adsorbed by the type A zeolites.
3A
3A is made by ion-exchanging the sodium in type 4A zeolite with potassium. The 3A molecular sieve will exclude most molecules except water, making it very selective.
4A
4A is the sodium form of the type A zeolite molecular sieve and is widely used as a general purpose drying agent. Under certain conditions, it can also be used for removal of ammonia, alcohols, carbon dioxide, H2S and other specific molecules.
5A
5A is the calcium-exchanged form of the type A zeolite molecular sieve and is primarily used for removing carbon dioxide, carbon monoxide, alcohols and other oxygenates, hydrogen sulfide, methyl and ethyl mercaptans, and others.
