Overview
SILIPORITE® NK 30 AP by Arkema is a synthetic zeolite type A molecular sieve supplied in potassium–sodium aluminosilicate form. With an effective pore opening of approximately 3 Å, it functions as a 3A molecular sieve for efficient and selective water adsorption. Its crystalline powder form disperses easily into formulations, providing high performance across coatings, sealants, insulating glass, and chemical processing.
Where it fits
- Building & Glass: moisture control in insulating glass units (IGUs) to prevent condensation while minimizing nitrogen desorption.
- Coatings, paints & polyurethanes: moisture scavenger that prevents foaming in sensitive systems.
- Fine chemicals & pharmaceuticals: adsorption of water in equilibrium reactions, improving yields and purity.
- General industrial: high-efficiency drying agent where controlled pore size (3 Å) is required.
Key advantages
- Precise 3 Å pore size for selective water adsorption
- Low nitrogen desorption – ideal for insulating glass applications
- Fine powder form – disperses easily in formulations
- Consistent viscosity in pastes for process stability
- Documentation available: SDS, TDS

Questions & Answers
Q: What type of molecular sieve is SILIPORITE® NK 30 AP?
A: It is a type A zeolite with a 3 Å pore opening (3A sieve), designed for selective water adsorption.
Q: Can it be used in polyurethane systems?
A: Yes. It prevents foaming by removing trace moisture from coatings, paints, and sealants.
Q: Why is low nitrogen desorption important?
A: In insulating glass applications, it reduces risk of pressure buildup and ensures long-term clarity.
Q: What formats are available right now?
A: Only palletized orders: 30 × 20 kg (44.09 lb) bags per pallet, or 4 × 80 kg (176.36 lb) drums per pallet.
