GPZ-10N
Zeolite Silver Antimicrobial
India's trusted inorganic Faujasite-X zeolite silver antimicrobial additive — moisture-triggered Ag⁺ ion-exchange for sustained, broad-spectrum microbial protection. Thermally stable to 600°C. Non-hazardous. CAS 130328-20-0.
GPZ-10N — Inorganic Zeolite Silver Antimicrobial Additive
GPZ-10N is Geocon Products' flagship inorganic zeolite silver antimicrobial additive — engineered for formulators who demand long-lasting microbial control without compromising material aesthetics, polymer colour, or processing performance, in a single non-hazardous white powder at dosages as low as 0.2%.
At the heart of GPZ-10N is a Faujasite-X crystalline aluminosilicate (zeolite) framework — one of the most thermally stable and chemically inert carrier matrices available for silver ion delivery. Unlike organic biocides that degrade rapidly under UV exposure, processing heat above 200°C, or ambient humidity, this inorganic zeolite silver additive retains its full structural and biocidal integrity through injection molding, twin-screw extrusion up to 320°C, and powder coating curing cycles — delivering antimicrobial performance that lasts the entire commercial product lifecycle, not just the weeks after production.
GPZ-10N operates through a moisture-responsive ion-exchange mechanism: silver ions (Ag⁺) are electrostatically bonded within the zeolite's microporous crystal channels and released only when triggered by ambient humidity — at a precise, sustained rate calibrated to inhibit Escherichia coli, Staphylococcus aureus, Aspergillus niger, and a broad range of bacteria, mold, algae, and odor-forming microorganisms. Because the ions release on demand rather than all at once, GPZ-10N avoids the rapid depletion common in soluble silver salts and ensures consistent log-reduction values batch after batch, even years after the product is manufactured.
One of the most persistent challenges in silver-based antimicrobials is photo-reduction — the unwanted conversion of Ag⁺ to metallic silver (Ag⁰) under UV light, causing grey, brown, or pink discoloration in white and translucent materials. GPZ-10N is precision-formulated at 0.80 ± 0.05 wt% silver — a loading calibrated specifically to prevent premature ion migration while sustaining efficacy. This makes it the technically preferred solution for medical-white polymers, transparent PET films, light-coloured architectural coatings, and food-safe packaging where colour deviation is commercially unacceptable.
In practice, GPZ-10N integrates at 0.2–1.0% in direct compounding and 1.0–3.0% in masterbatch let-down, distributing uniformly across PP, PE, ABS, PC, nylon, epoxy, acrylic emulsion, PU, and silicone systems — without the milling, wetting agents, or compatibility additives often required by conventional antimicrobial powders. Its micronized D50 of 3–7 µm produces no noticeable surface roughness, optical haze, or mechanical property loss, making GPZ-10N one of the most substrate-versatile inorganic antimicrobial additives available to the Indian and global specialty chemicals market.

GPZ-10N is classified as non-hazardous under standard transport and chemical handling guidelines. It exhibits low toxicity when used as intended. Always refer to the current Safety Data Sheet (SDS) and observe standard chemical handling precautions listed below.
Non-Hazardous Classification
GPZ-10N is classified as non-hazardous under standard transport and chemical handling guidelines — no special transport restrictions or hazmat documentation required.
Low Toxicity Profile
Silver-exchanged Zeolite is considered low in toxicity when used as intended. Avoid ingestion and prolonged direct skin contact. Not classified as a carcinogen or mutagen.
Dust Inhalation Precaution
Fine powder may cause temporary mechanical irritation to the respiratory tract. Use appropriate dust masks (FFP1/FFP2) or respirators during handling and powder transfer operations.
Eye Contact Protection
Dust particles may cause mechanical irritation. Wear protective eyewear — safety glasses or chemical splash goggles — to prevent eye exposure during handling.
Skin Contact Precaution
May cause mild dryness or irritation with prolonged contact. Use chemical-resistant gloves (nitrile or latex) while handling bulk quantities in production environments.
Ventilation Requirements
Handle in a well-ventilated area or under local exhaust ventilation (LEV) to minimise airborne dust concentration below occupational exposure limits.
Chemical Stability
GPZ-10N is chemically stable, non-reactive, non-flammable, and does not decompose under normal processing or storage temperatures. Avoid contact with strong mineral acids.
Environmental Safety
Product is insoluble and non-leaching — presents low risk to the environment when used correctly. Avoid direct bulk release into waterways, drains, or natural water bodies.
Storage Safety
Store in a cool, dry location away from moisture sources. Keep bags tightly sealed to maintain performance and prevent absorption of atmospheric humidity.
Regulatory Compliance Note
Always consult local regulations for specific permissible limits of silver-containing additives, particularly in food-contact and medical device applications. Regional limits may vary.
Storage Conditions
Store in a cool, dry, well-ventilated area. Keep bags or containers tightly sealed to prevent moisture absorption and preserve product performance over the shelf life.
Avoid Moisture Exposure
Zeolite materials can readily absorb ambient humidity — prolonged moisture exposure may affect ion-exchange capacity and performance. Always reseal packaging immediately after use.
Temperature Stability
Stable under normal ambient temperatures. Avoid direct exposure to high humidity or extreme temperature swings during storage. Do not store near open drains or wet areas.
Handling Precautions
Handle with care to minimise dust formation. Use appropriate PPE — gloves, dust mask/respirator (FFP1 minimum), and safety glasses during all production handling operations.
Bulk Transfer Safety
When transferring powder between vessels, use enclosed dust-controlled equipment or local exhaust ventilation systems to minimise airborne particulate exposure in the workplace.
Compatibility
Chemically inert and compatible with most polymers, coatings, ceramics, and adhesive systems. Avoid strong mineral acids (HCl, H₂SO₄) that may degrade the Zeolite crystal structure.
Spill Response
In case of spillage, sweep up carefully with a soft brush to avoid generating airborne dust. Collect in a labelled bag and dispose of according to local environmental regulations.
