KBS-03-B is a calcined synthetic zeolite powder .After high-temperature calcination, the zeolite loses most of its internal moisture, creating a highly porous, activated structure. It can be used directly as an adsorbent or desiccant in various applications.
The product is a white free-flowing powder with excellent physical properties, including a static water adsorption capacity of ≥24.50 wt%, a 325-mesh screen residue of ≤0.05 wt%, and a packing moisture content of ≤2.00 wt%. These characteristics ensure stable adsorption activity during storage and transportation.
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.

Product Advantages
l 1. High adsorption capacity
Static water adsorption ≥24.50 wt% (RH75%, 25°C), higher than ordinary silica gel and some activated alumina products. It maintains efficient adsorption even in low-humidity environments.
l 2. Selective adsorption without affecting system performance
Adsorbs only water molecules and small polar molecules, not solvents, resins, pigments, or other macromolecular components. This ensures chemical stability and final product quality.
