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-1 is a strong blowing catalyst that can be used in a wide range of polyurethane foams, including flexible molded, semi-flexible, polyether slabstock and low-density spray foams.
It has a strong catalytic effect on the blowing reaction and can be balanced by the addition of a strong gelling catalyst such as Crystalline or DC A33-LV catalysts.
Shelf Life
12 months/date of manufacture.
