Traditional Defoamers

Selecting the best defoamer for a given formulation requires finding a balance between the defoaming power or strength of the defoamer and the compatibility and solubility of the defoamer in the system. Air Product’s offers a full spectrum of traditional defoamer chemistries including organic oil-based, mineral-oil based, silicone based technology to meet your formulating needs.

Surfynol DF-178

A formulated silicone-based defoamer and de-aerator (100% active liquid). Surfynol DF178 defoamer was developed specifically for applications in water-borne coatings and graphic arts that demand both powerful defoaming and defect-free surfaces. Provides strong defoaming and microfoam control and is particularly effective in spray applications. APE-free.

Surfynol DF-220

An organic defoamer (100% active liquid). Surfynol DF-220 defoamer is a proprietary silicone-free additive that provides rapid and sustained defoaming in water-based printing inks, coatings and adhesives systems. Surfynol DF-220 defoamer is ideally suited for architectural and medium to high PVC systems. APE-free.

Surfynol DF-37

A nonionic, organic defoamer (100% active liquid). Surfynol DF-37 defoamer is a proprietary acteylenic-based additive that provides foam control and surface wetting in water-based formulations. FDA compliances and APE-free.

Surfynol DF-58

A silicone-based defoamer (100% active liquid). Surfynol DF-58 defoamer is a proprietary formulation that provides strong foam control and de-aeration performance in water-based formulations. APE-free.

Surfynol DF-62

An ether-modified polysiloxane defoamer (100% active liquid). Surfynol DF-62 defoamer is a proprietary formulation that provides excellent balance of initial foam knockdown and sustained antifoaming over time in water-based formulations. APE-free.

Surfynol DF-66

A modified polysiloxane based Surfynol DF-66 defoamer is a proprietary formulation that provides excellent balance of initial foam knockdown and sustained antifoaming over time in water based formulations. FDA compliances and APE-free.

Surfynol DF-695

A silicone emulsion defoamer (46% active liquid). Surfynol DF-695 defoamer is a proprietary emulsified silicone additive. Provides initial and sustained defoaming performance in water-based formulations. FDA compliances and APE-free.

Surfynol DF-70

An organic defoamer (100% active liquid). Surfynol DF-70 defoamer is a proprietary nonsilicone defoamer that provides effective foam knockdown and sustained efficacy in water-based formulations. Water dispersible and excellent in acrylic and styrene-acrylic systems. FDA compliance.

Surfynol DF-75

An organic defoamer (100% active liquid). Surfynol DF-75 defoamer is a proprietary mineral oil-free, nonsilicone defoamer that provides effective foam knockdown and sustained efficacy in water-based formulations. Offers excellent letdown and grind defoaming in architectural and industrial coatings systems. Emulsifiable in water and excellent in acrylic systems. FDA compliances and APE-free.
