Additional Information & Regulations

• Safety precautions: Strong oxidants, e.g. nitric acid, can cause violent reactions with ion exchange resins.
• Toxicity: Refer to the safety data sheet for product description, transport, storage, handling, safety, and ecology data.
• Disposal: Ion exchange resins must be disposed of according to the European waste nomenclature in the European Community.
• Storage: Store above freezing point of water, under roof, dry, and out of direct sunlight. If frozen, thaw gradually at ambient temperature before handling or use. Do not accelerate thawing.
• Packaging: Packaging stability is limited to 24 months under recommended storage conditions. Use within this timeframe or check packaging condition regularly.
