Dabco DC5LE catalyst is a low-emission, reaction-delayed catalyst that promotes emulsification time and maintains low activity. Dabco DC5LE catalyst strongly promotes the urethane (polyol-isocyanate) reaction without increasing amine emissions, and can be used to meet automotive OEM emission standards, such as VDA278. Dabco DC5LE catalyst has a wide range of formulations and can be widely used to meet the required processing and reactivity requirements.

Keep unopened for two years


Storage and transportation:

Should be sealed and stored in a dry, cool and ventilated warehouse



200KG/drum Storage: It is recommended to store in a dry and cool area with proper ventilation. After the original packaging, please fasten the packaging cover as soon as possible to prevent the water and other substances from mixing into the product and affecting its performance. Store in a cool, dry place, keep the container sealed and avoid contact with oxides. Do not breathe dust, avoid skin and mucous membrane contact. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes. Store contaminated clothing separately and wash it before reuse. Maintain good hygiene habits. The company recommends that all polyurethane catalysts be stored in a dry, cool and properly ventilated place. All storage containers must be well sealed to avoid contact with water or other influential substances, because this may change the performance of the product in use. The storage temperature is 10°C to 30°C. Lower or higher temperatures are not suitable and should be avoided as much as possible.
