Storage Information
Recommends that our catalysts be stored in a dry and cool area under appropriate ventilation conditions. Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products’ performance in the end use. The optimum storage temperature is between 10 °C and 30 °C. Lower and higher storage temperatures are not preferable and should be avoided.
Applications
DC A-33 is used in the manufacture of all types of polyurethane foam. It can be used as a 3:1 replacement for Crystalline catalyst in all foam formulations. For example, 0.3 pphp
DC A-33 replaces 0.1 pphp Crystalline catalyst.
Shelf Life
12 months/date of manufacture.
