SILIPORITE® NK 30 AP from Arkema is a synthetic Type A zeolite molecular sieve powder supplied in potassium-sodium aluminosilicate form.
With an effective pore opening of approximately 3 angstroms, it functions as a selective 3A molecular sieve for removing water while excluding many larger molecules. Its fine powdered form disperses into compatible formulations for moisture control in insulating glass, polyurethane systems, coatings, sealants, chemical processing, and other applications requiring efficient water adsorption.

| Approximately 3 Å pores | Allows water molecules to enter the zeolite structure while excluding many larger compounds. |
| Powdered form | Supports dispersion through compatible liquid, paste, coating, adhesive, and sealant formulations. |
| High water capacity | Provides moisture-scavenging performance under low-humidity conditions. |
| Low nitrogen desorption | Helps limit gas release in insulating glass formulations after incorporation into a compatible sealant system. |
| Controlled particle size | Supports consistent dispersion and formulation behavior when suitable mixing equipment is used. |
Application and trial guidance
- Evaluate performance using the actual resin, solvent, coating, adhesive, sealant, or chemical formulation.
- Confirm compatibility with formulation viscosity, cure behavior, pot life, appearance, and finished-product performance.
- Add using suitable mixing and dust-control equipment to achieve uniform dispersion.
- Minimize exposure to ambient humidity before and during incorporation into the formulation.
- Optimize dosage based on incoming moisture, target residual water, formulation chemistry, and processing conditions.
- For polyurethane systems, verify foam reduction, cure response, adhesion, and mechanical properties through controlled trials.
- For insulating glass systems, qualify moisture capacity, nitrogen desorption, sealant compatibility, and long-term durability.
- For chemical reactions, evaluate both water removal and possible adsorption of other small molecules.
Qualification note: Arkema recommends thoroughly testing the product in the proposed application before commercialization. Performance depends on the complete formulation, processing method, dosage, moisture loading, and end-use requirements.

Storage and handling
- Store in the original waterproof packaging in a dry, covered location.
- Keep the inner polyethylene liner or container tightly closed until use.
- Reseal partially used packaging immediately to reduce atmospheric moisture pickup.
- Minimize exposure to humid air during transfer, weighing, and formulation.
- Use suitable local exhaust ventilation where airborne powder may be generated.
- Avoid breathing dust and wear personal protective equipment specified by the current SDS and site risk assessment.
- Use clean, dry transfer and mixing equipment.
- Protect the powder from liquid water, oils, solvents, dust, and foreign contamination.
Important: Active molecular sieve begins adsorbing moisture immediately after exposure to air. Review the current Arkema Safety Data Sheet before handling, transfer, cleanup, or disposal.

Questions & answers
What is SILIPORITE NK 30 AP?
SILIPORITE NK 30 AP is a powdered synthetic Type A zeolite manufactured by Arkema. Its potassium-sodium aluminosilicate structure provides an effective pore opening of approximately 3 angstroms.
Is NK 30 AP a 3A molecular sieve?
Yes. Its approximately 3 Å pore opening allows it to adsorb water selectively while excluding many larger molecules.
What is its water adsorption capacity?
The Arkema specification lists a minimum water adsorption capacity of 21.5 wt.% at 10% relative humidity and 23°C ±2°C.
What is the particle size?
The specification permits no more than 2 wt.% of the powder to be retained on a 20 µm mesh, meaning at least approximately 98% passes through that screen under the stated test method.
Can it be used in polyurethane systems?
Yes. Arkema identifies polyurethane paints, coatings, and sealants as applications where the powder can adsorb residual water and help prevent moisture-related foaming.
Why is low nitrogen desorption useful in insulating glass?
Limiting nitrogen release helps reduce internal gas buildup after the molecular sieve is incorporated into a compatible insulating-glass sealant formulation.
Can it be used in chemical reactions?
Arkema identifies water adsorption in chemical-equilibrium reactions as an application. The actual formulation and process should be tested to confirm selectivity, compatibility, and performance.
What package sizes are available?
The current Sorbents Direct listing offers a 600 kg pallet containing thirty 20kg bags or a 320kg pallet containing four 80kg drums.
Are smaller quantities available?
This product is currently offered in palletized bag or drum quantities. Smaller individual packages are not listed at this time. Reach out if you need alternative sizes.
What documentation is available?
The Arkema Product Data Sheet and applicable Safety Data Sheet are available. A lot-specific Certificate of Analysis may also be requested when available.
