In this paper, different catalysts will be evaluated in ecomate® spray foam formulations to determine which choice of catalysts promotes longer shelf life. The liquid polyol blends will undergo an accelerated shelf life aging at 50 °C (122 °F) for four weeks. Many different catalyst types will be evaluated including metal, amine, blowing, and gelling families. The intent is to meet or exceed a six month shelf life without compromising other physical properties of the finished product.
