Recommendations for use.

Dabco DC5LE catalyst is recommended for use as a co-catalyst in soft, hard and CASE materials, especially for NVH formulations.

Dabco DC5LE catalysts are formulation tolerant and can be used in a wide range of applications to suit the required processing and reactivity requirements.

Product Usage:

Dabco DC5LE is a co-catalyst for low emission reaction delays;

Dabco DC5LE provides a strong boost to urethane (polyol-isocyanate) reactions while keeping emulsion time and service life unchanged;

Dabco DC5LE does not increase amine emissions and can be used in polyurethane foams that are required to meet automotive OEM emission regulations such as VDA 278;

Dabco DC5LE can be used as a co-catalyst in flexible, rigid and CASE materials and is particularly suitable for NVH formulations.

Shelf Life.

Keep unopened for two years

Storage and transportation:

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


200KG/drum Storage: it is recommended to store in dry and cool area with proper ventilation. Please fasten the packaging cover as soon as possible after the original packaging to prevent the mixing of other substances such as moisture and other substances that may affect the product performance. Store in a cool and dry place, keep the container sealed and avoid contact with oxides. Do not inhale dust and avoid contact with skin and mucous membranes. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes. Store contaminated clothing separately and wash before use. Maintain good hygiene practices. The company recommends that all polyurethane catalysts be stored in a dry, cool and properly ventilated area. All storage containers must be well sealed to avoid contact with water or other affected substances, which may alter the performance of the product in use. The storage temperature is 10°C to 30°C. Lower or higher temperatures are inappropriate and should be avoided if possible.
