Purpose: Compare spray application performance at equal weight loadings as
a function of formulation storage time
• The mass of HFC or HFO blowing agent was held constant. The density for the Opteon™ 1100 (FEA-1100) sample was adjusted by using water.
• Graco HV-R Reactor, 125F hoses, 1600 psig, AR4242 mix chamber
• Both systems were aged in 5 gallon pails in a controlled laboratory environment (room temp).
