Molecular Sieve Powder

Sorbchem India's Activated Molecular Sieve Powder is a dehydrated synthetic powder made from a foam of 3A and 4A molecular sieves. This Powder which is used in Epoxy and Polyurethane Coating , Epoxy Paints And Resins , Adhesive Application such as Polyurethane formulations , Epoxy Flooring and even in Polyurethane Flooring.

The molecular sieve powder, or Zeolite powder, an inorganic cation exchanger, is widely used in water treatment, catalysis, and nuclear waste management. Its foamless structure makes it an effective additive in paints and polymers, where it removes moisture and air bubbles. This dehydrated synthetic powder excels at moisture adsorption, acting as a moisture scavenger to extract water and contaminants from various systems, enhancing product quality and shelf life. It also prevents CO2 formation in polyurethane systems. The 3A zeolite powder, a potassium form of type A aluminosilicate, can adsorb molecules with a diameter of less than 3 angstroms (0.3 nm).
