PC41 is a high-activity trimerization catalyst for rigid polyurethane foam with excellent foaming/gelling ability. It is usually shared with other catalysts.

PC41 is mainly used to catalyze the reaction of polyurethane and polyisocyanate. In fact, the catalytic activity of polyurethane is slightly higher than that of polyisocyanate reaction. Foam, sprayed rigid foam, molded rigid foam;

PC41 is more suitable for polyisocyanate rigid foam board, various foaming agent foaming (including full water foaming) and other processes, in the water foaming rigid foam system Have excellent performance;

PC41 is also suitable for microcellular polyurethane elastomers and high resilience foam plastic products.

Storage and transportation:

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


200KG/bucket 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 mixing of other substances such as waterproof grade and affect the performance of the product.

Store in a cool, dry place, keep the container tightly closed, 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, take a shower and change clothes.

Store contaminated clothing separately and wash it before use. Maintain good hygiene habits.

The company recommends that all polyurethane catalysts be stored in a dry, cool and well-ventilated place. All storage containers must be well sealed to avoid any impact on water or others. Contact with other 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 inappropriate and should be avoided as much as possible.
