PC41 has a high-activity polyurethane hard foam high-polymerization trimerization catalyst with excellent foaming/gelling ability, and is usually shared with other catalysts.

PC41 is mainly used for the catalysis of the reaction between polyurethane and polyisocyanate. In fact, the catalytic selectivity for polyurethane is slightly higher than that of polyisocyanate. It is often used for laminated polyurethane hard foam, spray hard foam, and molded hard foam;

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

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


Storage and transportation:

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


Packaging and storage:

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.
