Air Products Offers Three New Defoamers

May 1, 2010

Air Products has introduced three new defoamers for the coatings, graphic arts and adhesive markets. These new defoamers are engineered to be alkylphenol ethoxylate (APE)-free and offer long-lasting foam control and defect-free surfaces. Surfynol DF-178 is a formulated defoamer and de-aerator that provides strong defoaming and microfoam control and is particularly effective in spray applications. It was developed to provide the defoaming strength of a silicone-based defoamer but with the superior system compatibility needed in the demanding higher gloss and clear coat applications used in waterborne coatings. Surfynol DF-220 is a mineral oil-based defoamer that was engineered to provide exceptional defoaming in architectural and high PVC (Pigment Volume Concentration) paints and coatings. This 100% active product contains no silica, silicones or APEs. Surfynol DF-110C defoamer is a defoaming/deairentraining agent useful for a wide variety of applications. This nonionic, water-free, and silicone-free material can be utilized in areas where foam prevention or foam elimination is necessary without causing film problems. Some of the benefits include microfoam elimination, long-lasting foam control, defect-free foam control,  and good dynamic wetting.
