Uses.
Clarified viscous liquid
Used as an efficient catalyst in the manufacture of polyurethane foams, coatings, adhesives and sealants. Used as a hardening catalyst for two-component polyurethane, polyester, nitrocellulose lacquers, inks and other coatings and warm air hardening type coatings with good oxidation resistance; used as a catalyst and drying agent for the production of polyurethane plastics, polyurethane coatings, silicone rubber and other uses.
Storage methods.
Room temperature, protected from light, ventilated and dry place, sealed
Storage and transportation.
Store in sealed containers and in a cool, dry place. The storage area must be locked and the key must be given to the technical experts and their assistants. The storage area must be kept away from oxidising agents and away from water sources.
Packaged in universal plastic and plastic sprayed iron or glass containers and transported according to general chemical regulations.
Packaging.
Packaging: glass containers, plastic containers, metal vessels resistant to chlorine corrosion are preferable for storage in sealed containers. Store in a cool, dry place, keep the container sealed and avoid contact with oxides. Do not breathe dust and avoid contact with skin and mucous membranes. No smoking, eating or drinking in the workplace. Shower and change clothes after work. Store contaminated clothing separately and wash before use. Maintain good hygiene practices.
