FoamStar® ST 2446 is based on a patented hyper-branched Star polymer compounded with high-end organo-silicone polymers. It is one of our best defoamers for zero to 50 g/l VOC, medium to low PVC premium paints. FoamStar® ST 2446 is a product of choice when other defoamers do not work. It allows for very good film appearance properties despite its very high efficiency.

Applications

FoamStar® ST 2446 has the following advantages:
Performance Highlights

• 30 – 50 % less dosage; very fast bubble break
• Excellent for zero to 50 g/l premium paints
• Good dispersability –> Excellent film appearance
• Works in highly tinted paints and against microfoam
• High persistency and works in high gloss paints

Environmental Aspects

• Low VOC – according to US-EPA 24 (2 %)
• Efficiency is better than conventional control defoamer

FoamStar® ST 2446 is primarily designed to be a letdown defoamer, but it may be added to the grind. If used in the grind, it is recommended to add approximately ¼ – ½ of the amount to the grind, and the remaining amount to the letdown.
