NOSIL 4291A is a PROVEN highly effective nonsilicone anti-foam and defoamer formulated for use in continuous and batch dyeing. Its anti-foam qualities are achieved through the use of special
non-silicone hydrocarbons and high quality emulsifiers which allow the product to rinse free of the fabric when the bath is dropped or rinsed upon exiting the steamer. Many products of this nature are effective only at maximum dyebath temperatures and function more as an anti-foam with little or no foam knock-down power. While the prevention of foam formation should be the first consideration, it is equally important to be able to kill foam without the use of excessive amounts of the product, or having to store both defoamers and anti-foams in the dyehouse. It is in this area that NOSIL 4291A excels and it can be added even at elevated dyeing temperatures without fear of splitting, scumming or spotting of the fabric.
The QUALITY of NOSIL 4291A is monitored by DYETECH, Inc.'s quality system which has been certified to meet the ISO 9001 internationally recognized quality standard.
Depending upon other dyebath components 0.5 to 2% o.w.g. or 0.1 to 2 g/l in continuous dyeing is generally effective over the entire processing cycle without any further additions.
