Amine Catalyst


  A-33 imparts a high level of activity and good physical properties to flexible foam systems.
Optimum performance of this catalyst can be achieved when it is used in conjunction with A-1 or A-10 in flexible foam formulations.

¢ºPerformance Evaluation
  A-33 was evaluated using bench foam techniques. The effects of varying tin at constant
amine and varying amine at constant tin were both evaluated. The ranges of tin and amine concentrations were well within the "operating range" of each. The dependent variables measured were: reactivity, top collapse, height of rise, breathability, density, cell count, and foam hardness(IFDs). Top and bottom gradients for breathability and density were defined.
