Strong adsorbents, such as molecular sieves, are useful for efficiently regulating humidity and moisture in liquids and gasses. It’s crucial to remember that adhesives, sealants, and coatings might suffer from moisture. Water vapor from fillers or surrounding air may combine with these products during manufacture. Contaminated gases, such as carbon dioxide, can also cause problems with moisture, which may lead to scorching and degradation. Molecular sieves are used as active desiccants in powder coatings, sealants, and adhesives to solve these issues and guarantee moisture-free final products.

Molecular sieves are not directly used in this procedure. Rather, during product handling and mixing, oil and active chemicals are combined with powdered molecular sieves to minimize the surrounding humidity.

Adsorbents 3A, 4A, and 5A that are powdered efficiently and non-reactively remove moisture from sealants, adhesives, and coatings. Generally, their usage involves 1% to 5% of the product’s weight, contingent on the water content of polyol and further additions such as pigments and fillers. These adsorbents are perfect for improving surface smoothness, minimizing weathering effects, removing foaming and bubbling, and lengthening shelf and pot life. They routinely solve moisture problems, are simple to operate, and work effectively.

Molecular sieve powders are effectively used in polyurethane systems, polysulfide and silicon systems, potting compounds, metallic paints, industrial coatings, pipe and tank coating, flooring, anti-corrosion application, and pigment and solvent drying.
