13X molecular sieve activated powder is a synthetic crystalline aluminosilicate with uniform micropores (approximately 10 Å). It is activated to maximize adsorption capacity, making it highly effective for moisture and gas removal in industrial applications.
Key Properties
- Physical Characteristics:
- Appearance: Typically white or light gray fine powder .
- Particle Size: Ranges from 2-4 μm for optimal dispersion and surface contact.
- Bulk Density: ≥430 kg/m³, ensuring efficient packing and stability.
- Adsorption Performance:
- Rapidly adsorbs moisture, CO₂, and volatile organic compounds (VOCs) due to its high surface area and selective pore structure.Prevents side reactions (e.g., bubble formation in polyurethane systems by scavenging trace water).
Primary Applications
- Moisture Scavenging:
- Used in two-component polyurethane adhesives and sealants to eliminate moisture-induced defects.
- Critical for insulating glass sealants to maintain clarity and adhesion.
- Industrial Protection:
- Rubber & Painting Industries: Acts as a desiccant to prevent moisture damage during production and storage.
- Coatings & Solvents: Incorporated as a pigment additive to adsorb impurities and enhance product stability.
- Specialized Functions:
- Selective adsorption of contaminants in solvents and coatings.
- Used in packaging for humidity-sensitive products.
