What is Activated Molecular Sieve Powder?

Trace amounts of water is an issue in the production and preparation of polyurethane (PU) products. Trace amounts of water in the polyol react with the isocyanate to form carbon dioxide, which results in foam. At the same time, a large amount of heat is released, which shortens the service life of the product. In special industries such as paints, coatings, resins, solvents, adhesives, etc., trace moisture will cause adverse effects. For example, in zinc metal or coatings, trace moisture will react with active zinc, aluminum and other metal pigments to generate hydrogen gas , it will cause the pressure in the tank to be too high, and even cause leakage in extreme cases.

XINTAO activated molecular sieve powder is the original molecular sieve powder after high temperature roasting and activation and have water removal process, which has excellent dispersibility and strong adsorption activity.

Adding this product to polyurethane, adhesive, paint, rubber and other product systems can effectively selectively absorb trace moisture and inhibit the occurrence of side reactions, thereby reducing the generation of air bubbles and extending the service life.

Chemical Principles: RHCO+H2O--RNH2+CO2
