BIO-SIL IGT/10 is a 10% emulsion of Polydimethylsiloxane specifically formulated for anti-foaming and de-foaming of most fabric and textile processing applications. BIO-SIL IGT/10 performs rapid, initial knock down and persistent hold down of foam generated by the addition of surfactants, water and agitation. BIO-SIL IGT/10 rapidly disperses into water-based systems with no effect to fabrics and textiles. Contains built in pH buffer to be stable over a wide pH range and does not cause yellowing.
Common Areas of Use.
Finishing & Sizing
As a processing additive: For maximum de-foaming efficiency, pre-dilute BIO-SIL IGT/10 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 IGT/10 to the water but rather vice versa. In processing applications as an additive, BIO-SIL IGT/10 in concentrations of 10 to 500 ppm can be added.
For end use: BIO-SIL IGT/10 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 fabric/textile processes and 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.
