Product Usage

Dabco PT303 is a strong foaming low-odor tertiary amine catalyst with similar performance to Polycat 5, but the odor is much lower than Polycat 5 and can strongly catalyze the reaction of urea (water-isocyanate);

Dabco PT303 can be used for different types of rigid foam plastics, especially rigid spray foam;

The dosage of Dabco PT303 can be adjusted according to the formula, actual application and requirements;

Dabco PT303 can be used in spray foam with Dabco PT302 and Dabco PT304.



Dabco PT303 catalyst is a high-efficiency polyurethane composite tertiary amine, which can strongly catalyze the urea (water-isocyanate) reaction of hard spray polyurethane foam, thereby greatly increasing the foaming reaction time. Dabco PT303 catalyst contains groups that can react with isocyanate and can form a chemical bond with the polyurethane foam matrix to reduce the odor of spray foam.


Typical physical properties:

Appearance light yellow transparent liquid

Specific gravity 0.84

Viscosity@25℃ mPa.s 5

Water soluble at 25℃, completely dissolved

Flash point, ℃ 72



Strong foaming catalyst with similar activity to Polycat 5 catalyst

Lower odor than traditional Polycat 5 catalyst



Dabco PT303 catalyst can be used in rigid foam applications, especially rigid spray foam.

The amount of Dabco PT303 catalyst can be adjusted according to the formula, use and requirements. Can be used together with Dabco PT302 and Dabco PT304 catalysts in spray hard foam formulations.


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.
