Polycat 31 catalyst is a low-odor tertiary amine designed for low-density, water-foaming, open-cell spray polyurethane foam (SPF).

Compared with BDMAEE [bis(dimethylaminoethyl) ether] catalyst, Polycat 31 catalyst has the ability to reduce the “smoked eyes” or “blue mist” during construction and improve the production operating environment.

Low odor amine catalyst

Promote polyurethane foaming reaction

Reduce amine emissions during spraying

Reduce “smoked eyes” or “blue fog” phenomenon



Polycat 31 amine catalyst can be used for rigid polyurethane spray foam.

Polycat 31 amine catalyst can be used as a single catalyst or auxiliary catalyst to reduce the use of BDMAEE [bis (dimethylaminoethyl) ether] foaming catalyst (such as Dabco BL-11 catalyst, Dabco BL-19 catalyst).


Product Usage:

Polycat 31 is a non-emission amine catalyst, mainly used in low-density, water-foaming open-cell spray polyurethane foam (SPF);

Polycat 31 can be used as the main catalyst alone or as a co-catalyst to reduce the amount of BDMAEE-based foaming catalysts (eg DABCO BL-11, DABCO BL-19).


Shelf life:

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.
