Low odor polyurethane rigid foam catalyst


Product name: 37 low odor polyurethane rigid foam catalyst

Alias: Catalyst 37, low odor polyurethane rigid foam catalyst, polyurethane rigid foam catalyst

Product description: 37 catalyst for low odor polyurethane rigid foam system

Low odor polyurethane rigid foam catalyst polyurethane rigid foam catalyst 37


37 catalyst is a low-odor polyurethane tertiary amine, suitable for low-density, all-water foaming, open-cell spray polyurethane foam (SPF).

37 catalyst is more selective for water-isocyanate foaming reaction. Due to its chemical structure, 37 catalyst can react with foam, thereby reducing amine odor.

Typical physical properties:

Appearance colorless transparent liquid
Proportion 0.92
Viscosity@25℃ mPa.s 17
Water-soluble 25℃ soluble
Flash point, ℃ >89


1. Reduce amine emissions and reduce odor

2. Selectivity to water-isocyanate reaction

3. Competitive use cost

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.
