Toxicity, handling and storage
Generally, isocyanates can irritate the skin locally, eyes and respiratory tract. When inhaled, they may damage mucous membranes. Although Vorite 689 is a low vapor pressure isocyanate based non-TDI prepolymer, however, proper handling precautions should be strictly followed when using the prepolymer in large quantities. This includes proper ventilation and the use of protective goggles, gloves and an apron. In case of skin contact, remove and wash immediately with plenty of soap and water. Any spills should be covered with wood chips and treated with a dilute solution of ammonia or ethanol (or methanol) in water and water before disposal.
Vorite 689 should be stored above 15℃ (60°F) temperature. If product is exposed to temperatures below this for prolonged periods, crystals may form or freeze. If this happens, melt it by heating to 65°C (150°F) for 1 hour, then stirring well. This action can only be performed once. If product freezes more than once, it should be discarded.
For Vorite 689 and Polycin 640-M1, Exposure to moisture should be minimized. After each use, it should be stored in an airtight container covered with dry air or a dry inert gas.
The above information is only a brief overview and does not necessarily whole. The latest MSDS should be read before using this material.
