High trimer conversion rate


Catalyst 46 is widely used in various polyurethane applications, such as PIP rigid board foam, semi-rigid foam molded instrument panel foam, PIR rigid foam, and Energy-absorbing rigid foam.

Product Usage

Catalyst 46 is used to promote the isocyanate reaction (trimerization reaction) and can be used in various rigid foams.

Shelf Life:

Keep it unopened for two years

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 product performance from being mixed with other substances such as waterproof grade. 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 clothes separately and use them after washing. Maintain good hygiene habits. The company recommends that all polyurethane catalysts be stored in a dry and cool place with proper ventilation. All storage containers must be well sealed to avoid contact with water or other influential substances, as 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.
