3A Molecular Sieve Granules Hygroscopic Agent
EN 1279:2018 Certified · Specialized Drying Solution for Insulating Glass
Core Product Features
High-Performance Adsorption System for Precise Insulating Glass Adaptation
Formulated with 3A synthetic zeolite (CAS 1318-02-1) and natural binders as the base, it can flexibly incorporate auxiliary materials such as calcium bentonite (CAS 97862-66-3) or calcined limestone (CAS 91053-52-0) based on application scenarios. The component ratio adjusts dynamically according to molecular sieve substrate properties, eliminating the need for fixed materials and meeting differentiated needs of various spacer materials (aluminum/stainless steel/plastic) and processes.

Application Guidelines
1. Pretreatment & Activity Testing
- Conduct Delta-T value test using Nedex special kit (50g sample + 50ml deionized water). Repeat testing if temperature difference <15℃ to ensure adsorption activity compliance.
- Reference Critical Value Comparison Table for Fresh and In-Production Sieves
2. Key Filling Process Points
- Timeliness Control
- Equipment Adaptation
3. Sealing & Storage Specifications
- Complete insulating glass sealing within 8 hours after filling. Avoid exposure to <0℃ environment within 4 hours post-sealing to prevent inner surface condensation.
- Store in 0-30℃, light-proof and moisture-proof warehouse. Shelf life: 18 months for metal drums/cartons, 9 months for big bags (with inner lining). Pre-test initial moisture content in extreme temperature/humidity environments.
