Overview
SILIPORITE® NK 10 AP by Arkema is a synthetic zeolite type A molecular sieve in potassium–sodium aluminosilicate form. With an effective pore opening of approximately 4 angströms (4A), it is a versatile moisture adsorbent for formulations and process drying across coatings, sealants, adhesives, and chemical manufacturing. Supplied as a fine powder, it disperses readily and acts as an in-situ moisture scavenger to help prevent foaming, gassing, and other water-driven defects.
Where it fits
- Coatings, paints & sealants (PU/epoxy): controls trace water to reduce CO₂ gassing, pinholes, blisters, and loss of gloss.
- Adhesives & elastomers: improves pot life and cure consistency in moisture-sensitive systems.
- Chemicals & intermediates: promotes equilibrium shift/yield by adsorbing water formed during reactions.
- Solvents & process fluids: drying of polar solvents and blends prior to use or packaging.
Key advantages
- Precise 4 Å pore size for efficient water uptake and small-molecule drying.
- Powder form for easy incorporation into liquid or paste systems; helps maintain uniform viscosity.
- Versatile across chemistries (PU, epoxy, acrylic, and other moisture-sensitive systems).
- Quality documentation available: SDS, TDS.

Questions & Answers
Q: How is 4A different from 3A sieves?
A: Both target water, but 4A can also adsorb some small polar molecules, making it more versatile for coatings and solvent drying. 3A is more water-selective (useful where selectivity is critical).
Q: Can I add it directly to coatings or adhesives?
A: Yes. NK 10 AP is a powder designed for direct incorporation as a moisture scavenger. Blend under good agitation and keep containers tightly closed to avoid pre-loading with ambient moisture.
Q: What’s the minimum order right now?
A: Pallet-only: 50 × 20 kg (44.09 lb) bags per pallet; total 1,000 kg (2,205 lb).
Q: How should I store it?
A: Store sealed in a dry area. Reseal opened bags promptly to prevent moisture pickup. Avoid prolonged exposure to humid air.
