WANNATE® 8312

• WANNATE® 8312 is of low toxicity by inhalation and skin absorption.
• The very low volatility of WANNATE® 8312 means that it should be of little hazard for brief exposures under normal conditions, e.g. in cases of small spillages.
• Nevertheless, WANNATE® 8312 is an isocyanate-based composition and should be of certain toxicity.
• It may cause mild eye irritation and slight skin irritation. It may pose problems of skin sensitization.
• Even under normal conditions, WANNATE® 8312 remains a reactive chemical and care should be taken to prevent it from coming into contact with the skin and eyes when handling it.
• Suitable protective clothing such as glove, protective spectacles and work suit should be worn.
• Splashes on the skin or in the eyes should be removed promptly by irrigation with clean water and the skin should be well washed with soap and water.
• In case of spills, evacuate and ventilate the spill area. Only worn protective clothing personnel should be involved in the spill cleanup and waste disposal operations.
• Spills can be covered with absorbent or sand, transferred into open containers, properly labeled and removed from the work area for decontamination with a suitable decontamination solution.
• All disposal methods must be in accordance with local environmental protect law and regulations.

• Since WANNATE® 8312 is a reactive chemical, reaction with atmospheric moisture happens easily and leads to the formation of insoluble urea and carbon dioxide gas, which can result in pressure build-up in closed containers and viscosity increase of the product.
• Containers must therefore be absolutely dry and carefully sealed after congested with nitrogen.
• Containers of WANNATE® 8312 should be kept properly closed and stored indoors at ambient temperatures (20-30°C) in a well-ventilated area. Storage at low temperatures (below 10°C) may lead to some crystallization; This material must, therefore, be protected from frost. If crystallization does occur, the material should be heated to 70-80°C to melt it out, strictly prohibit over heating at local part and should then be thoroughly agitated before use.
• Prolonged storage over 50°C is prohibited in order to avoid formation of insoluble solid and viscosity increase of the product. If the production is overdue but its main physical and chemical properties are in the guide line, the using properties may not be affected.
• Under recommended storage conditions, the shelf life of WANNATE® 8312is six months from the production date.
