Delay polyurethane foaming reaction, improve the fluidity of polyurethane foaming products
Widely applicable polyurethane catalyst
Dabco BL-17 is a delayed tertiary amine catalyst designed to slow down the initial reaction rate, primarily used to catalyze the reaction of water-isocyanates in flexible and rigid polyurethane foam formulations;
Dabco BL-17 is suitable for all types of flexible foams. In the early stages of the reaction, its catalytic effect is not obvious, but as the reaction proceeds and the temperature rises, Dabco BL-17 unblocks and its reactivity rises rapidly, prolonging the emulsion time, partially replacing other foaming catalysts, and delaying emulsion without affecting post-curing;
Dabco BL-17 can also be used in some polyurethane molded rigid foams.
Keep unopened, 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. Air Chemicals recommends that all polyurethane catalysts be stored in a dry, cool and properly ventilated area, and that all storage containers 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.
