- Safety and Health
Contact with the skin can cause inflammation including a rash, while contact with the eyes can cause severe pain, and visual disturbance may result in the event of excessive exposure. Inhalation of the vapor of MDI can cause bronchial asthma, headaches, or breathing difficulties, and its ingestion can cause irritation and inflammation of the gastrointestinal tract. In cases of contact with the skin, rinse the affected area completely with plenty of water or soapy water. In cases of contact with the eyes, rinse immediately with plenty of water or soapy water for 15 minutes, and seek professional medical help. In cases of MDI vapor inhalation, move the affected individual to a place where there is plenty of fresh air, keep him/her in a warm, stable condition, and perform artificial respiration if needed. In cases of ingestion, allow the affected individual to vomit with their head positioned lower than the hip to prevent suffocation from respiratory tract inhalation, and provide symptomatic treatment. Seek medical help if necessary. in the event of a fire, extinguish with a carbon dioxide fire extinguisher. In the event of a large fire, extinguish with water.
- Application
Cosmonate CG-33S is a special modified MDU, which is used for making sound absorbers, which reduce noises from various sections of automobiles, and for making vibration reducers. When applied to low-density products, it provides good moldability and satisfactory sound absorptiveness. In addition, Cosmonate CG-33S can be also applied to the automobile headrests and furniture as well as automobile sound absorbers.
- Storage and Handling
The optimal storage temperature for CG-33S is 20~35℃. Caution is needed to prevent moisture from being mixed in the storage container, which should be sealed by dry nitrogen gas if possible. When working with MDI, proper safety equipment should be worn, and a ventilation or gas mask should be used if necessary. After work, wash completely with soapy water. Contaminated work clothes should be washed and cleaned for the next use.
