Zeolites are microporous crystalline aluminosilicates, which allow water and other cations to be absorbed, thus filling the micropores.
Zeolites are a group of minerals which include aluminosilicates formed by the AlO4- and SiO4 tetrahedron joined by vertices of oxygen that contain interchangeable positive ions (cations such as Na +, K +, Ca2 +, Mg2 + among others). These minerals belong to the tectosilicates that make up about 75% of the earth’s crust, which is why zeolites are relatively easy to find in the natural state.
There are more than 40 different types of natural zeolites, and each one of them has a slightly different composition that allows the absorption of some or other molecules. The most common Zeolites are the analcime, cabazite, heulandite, natrolite, phillipsite and the stilbite. They have a high cation exchange capacity facilitating the absorption of water molecules, ammonium and heavy metal ions.
Synthetic Zeolite is a molecular sieve supplied in powder form. It is the optimal solution for the elimination of traces of water in coatings, sealants, adhesives or resins. It is a desiccant that controls the odor by adding it when making the products.
Zeolites are a type of desiccant and agent against sustainable pollutant compounds since they do not represent practically any impact on nature nor are they a risk to human health.
