Molecular sieves powder is a desiccated synthetic powder form of 4A and 3A molecular sieves and is used in some special adsorbents applications including petrochemical product purification for increasing strength and creating a pollution free atmosphere. Molecular sieves are a comprehensive sodium silicate and aluminum oxide structure, which permits the adsorption of several molecules on the basis of its polarity and size.
The molecular sieve powder is also used for compounding and formulating applications. It is even helpful in reducing the level of moisture significantly along with a high adsorption capacity. All these adsorbents function using a simple physical procedure, so that no hazardous reactions are formed that could affect the overall production properties. Molecular sieves powder coating for anti-corrosion treatment has also been widely accepted by various industries.

Why use molecular sieve powder?
Water, even in small quantities, reacts readily with the isocyanate group to form CO2, which creates instability in the system. These sieves are the strongest water scavengers as they absorb water at extremely low concentrations. Besides eliminating foaming or bubbling in the system, the sieve powder also helps in keeping the weathering effects, such as blistering and cracking, away.

Metallic Coatings for Anti-corrosion and Marine Applications
Applications
Applications
- Paints
that contain different metallic compounds, including copper, tin or
zinc, require a water-free formulation which is where the molecular
sieve powder helps. The molecular sieve powder when added to the formulation ensures that proper stability is maintained during the storage process.
