EMERALD SPECIALTIES GROUP: Defoamers
This company, a business group of Emerald Performance Materials, has introduced two new 100% active FOAM BLAST® defoamers for coatings and graphic arts, including both aqueous and energy curable applications. FOAM BLAST 4213 is an organo-modified silicone (OMS) synthetic antifoam product, while FOAM BLAST 4149 is a synthetic block copolymer composition developed as a non-silicone alternative. Both products reportedly offer excellent initial and long-term foam control for products such as interior and architectural coatings and flexographic inks.
Both defoamers can be added at low use levels (0.2-0.6%) during pigment grinding or let-down to reportedly achieve long-term foam control and a superior finish free of defects, craters or fisheyes caused by foam. Both are low-VOC and free of alkylphenol ethoxylates (APE).
