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.
