Product Description Use Level wt %
Airase 5100 Defoamer The strongest defoamer of the SSDL defoamer series. Designed for applications where 0.05–0.5
strong defoaming is required and the formulations are not sensitive to cratering.
Airase 5200 Defoamer Designed for applications where strong defoaming is required and the formulations 0.05–0.5
are not particularly sensitive to cratering. Provides excellent long-term, persistent
defoaming in formulations. Better film compatibility than Airase 5100 defoamer.
Airase 5300 Defoamer Designed for applications where strong defoaming is required with good long-term 0.05–0.5
persistency, especially in high shear applications.
Airase 5400 Defoamer Designed for applications where strong defoaming is required with good long-term 0.05–0.5
persistency, especially in high shear applications. Better film compatibility than
Airase 5300 defoamer.
Airase 5500 Defoamer Can be incorporated in the grind or used as a let-down defoamer. Designed for 0.05–0.5
applications where good defoaming is required with good long-term persistency
and film compatibility.
Airase 5600 Defoamer Can be incorporated in the let-down of a coating or ink. Airase 5600 defoamer 0.1–0.5
provides an excellent balance of effective defoaming and film compatibility.
Airase 5700 Defoamer Formulated for incorporation in the let-down of a coating or ink, and has the best 0.1–0.6
compatibility in the SSDL defoamer series. Airase 5700 defoamer provides an
excellent balance of effective defoaming and film compatibility.
