Dabco NE500 catalyst is a non-emitting tertiary amine, used as a catalyst for polyurethane bulk sponge, which can promote the urethane reaction. The Dabco NE500 catalyst has reactive functional groups and can react with the polyurethane matrix, so it will not cause emissions.
Dabco NE500 catalyst is used in soft bulk sponge applications to meet Certipur or LGA requirements. For polyurethane applications requiring low VOC and low emissions, the Dabco NE500 catalyst is a replacement for the non-emission demand of the DABCO 33-LV catalyst.

It is recommended to use Dabco NE500 catalyst in water foaming, dichloromethane (MC) or other block polyurethane foam systems that replace blowing agents. Dabco NE500 catalyst is compatible with other commonly used polyurethane catalysts and additives, and is easily miscible with polyols and polyol/water mixtures.
Dabco NE500 is a non-emission amine catalyst used to promote the urea (water-isocyanate) reaction. It will react into the polyurethane matrix, so it will not produce organic volatiles;
Dabco NE500 is also used in flexible bulk foam (polyether and polyester) applications to meet Certipur or LGA requirements;
Dabco NE500 is a non-emission catalyst that can improve foam fluidity and can replace Dabco 33-LV catalyst;
Dabco NE500 can be used in any polyurethane foam system such as water foaming and methylene chloride foaming.
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.
