Product introduction: |
The catalyst is a highly reactive tertiary amine catalyst, its chemical composition is pure pentamethyldiethylenetriamine(PMDETA). |
Application: |
The catalyst is generally used in rigid foam can improve the effect of strong foam bubble mobility, it is often as a total catalyst, dimethyl cyclohexane, dimethyl ethanolamine share. Less fluorine rigid formula, due to the increase in moisture, accelerate the foam reaction. |
Safety and Handling Precautions: |
According to the classification system of the U.S. Transport Department, the catalyst will be classified as alkaline corrosive liquid; if contact with skin, eyes, lungs and mucus membrane, the product is now significant toxicity and can cause severe irritation. Be careful to avoid such products contagious skin and eyes, and to avoid breathing vapors. In dealing with such products, to wear chemical protective masks, ethyl rubber gloves, rubber boots and aprons. For exposure in the aerosol of this product are required to wear breathing apparatus to protect. Once a contagious skin or eyes, the need to immediately wash the affected area with plenty of water for at least 15 minutes and seek medical advice immediately. |
