Molecular sieve Zeolite powder 3A 4A 5A 13X supplier

KBS-03-B belongs to the molecular sieve activated powder family. Its core advantage is selective adsorption. Synthetic zeolite has a regular, precisely controlled microporous structure that enables selective adsorption based on molecular size and polarity. In complex systems, it adsorbs target water molecules without interacting with solvents, resins, or pigments.

This property is particularly valuable in polyurethane (PU) systems. Any trace moisture can react with isocyanate components to form CO₂ gas, causing bubbles, pinholes, and other defects in coatings or adhesives. KBS-03-B captures this trace moisture and eliminates CO₂ formation at the source.

After high-temperature calcination, internal moisture is fully removed, leaving a highly developed pore network. Its 325-mesh ultrafine particle size ensures tight mixing and excellent dispersion in polymer systems without agglomeration or sedimentation. The product also maintains structural stability at high temperatures (e.g., 550°C for 2 hours), demonstrating the excellent thermal stability of synthetic zeolite.
