BIO-SIL IGI/30 is a 30% emulsion of Polydimethylsiloxane specifically formulated for all medium - heavy anti-foaming and de-foaming of water-based ink and coating systems. BIO-SIL IGI/30 has rapid knock down and exceptional hold down of all foam generated from the addition of water and agitation. BIO-SIL IGI/30 rapidly disperses into water-based ink and coating systems with low tendency to affect lay and gloss at small doses.
Common Areas of Use.
Water-based ink and coating systems
Water-Based overprint varnishes
Printing press ink pumps/agitation
Waste Water Treatment
Waste Cooling tower systems
As a processing additive: For maximum de-foaming efficiency in let down and grind, pre-dilute BIO-SIL IGI/30 with 0.1 to 0.5 parts by weight of the total amount of water before adding to the foaming system. Do not add the BIO-SIL IGI/30 to the water but rather vice versa. In processing applications as an additive, BIOSIL IGI/30 in concentrations of 10 to 500 ppm can be added.
For end use: BIO-SIL IGI/30 emulsion can be added directly from the original shipped container into the foaming system. A concentration in the range of 0.1 to 0.5% has been determined as a good starting amount for water-based ink and coating applications.
- Testing before formulating should still be carried out as systems vary.
Material Safety Data Sheets are available upon request.
The shelf life period without testing is 12 months from date of manufacture, if stored in the original unopened container at 4°C to 27°C.
Mild agitation should be carried out if stored as the nature of any emulsion is to separate without agitation over extended periods of storage
