CT REACTIVE SHIFT=100*[(CT 17 −CT 0 )/CT 0 ]  Formula X:

wherein

CT 17 means a composition's CT after the composition's B-Side comprising has been aged at 40° C. in a closed, pressure-rated, glass container that was placed in an oven for 17 days;

CT 0 means a composition's CT after the composition's B-Side comprising has been aged at 40° C. for 0 days;

and

TFT REACTIVE SHIFT=100*[(TFT 17 −TFT 0 )/TFT 0 ]  Formula Y:

wherein

TFT 17 means a composition's TFT after the composition's B-Side comprising has been aged at 40° C. in a closed, pressure-rated, glass container that was placed in an oven for 17 days;

TFT 0 means a composition's TFT after the composition's B-Side has been aged at 40° C. for 0 days

wherein CT means the elapsed time between the moment the A-side is mixed with the B- Side and the formation of a fine froth in the composition and

wherein TFT means the elapsed time between the moment the A-side is mixed with the B-Side and the time on which an outer skin of the polyurethane foam product loses its adhesive quality.
