Low VOC Foam Controlling Agent Technology

Overview:

Air Products is offering Low VOC Foam Controlling Agent Technology based on alkyl glycidyl ether-capped polyamines for license. Undesirable foaming can lead to inefficient mixing, poor productivity, reduced vessel capacity and perhaps even equipment failure in many common industrial processes. Foaming in industries such as drilling can lead to operating difficulties with significant economic consequences. In other applications such as coatings, inks, adhesives and agricultural applications, foam control agents that also have surface active properties are desirable because they reduce surface defects and processing inefficiencies. Not all alkyl glycidyl ether-capped polyamines are capable of reducing or eliminating foam. It is the correct combination of polyamine and alkyl glycidyl ether group and an optimum degree of adduction that is essential for the reduction and/or elimination of the foam.

Benefits:

  • Reduces or eliminates foam
  • Low odor and low color
  • Agent is 100% active ingredient, not requiring carrier fluids, solvents or other additives
  • Improved shelf stability
  • Low VOC
  • Reduced dynamic surface tension
  • Reduction of coating or printing ink defects
  • Capable of high speed applications
