Non-Silicone Defoamers for Industrial Applications

TRANS-245

TRANS-245 is a water-based, biodegradable, non-silicone defoaming blend developed to prevent excessive foaming in C.I.P. cleaning systems and auto-dishwashing applications. It is alkali-soluble and stable, performs in high temperature systems and high protein soil conditions such as whey evaporators, and possesses mild detergency. TRANS-245 is effective within the food industry where direct and indirect food contact is not expected to occur.

Controlling Foam

To control foam, TRANS-245 defoamer is normally added directly to the foaming product or process. A good starting point is 0.2 to 0.5% by weight in an aqueous system. For example, a standard recommendation is 3 oz. of TRANS-245 for each 10 gallons of liquid caustic soda. TRANS-245 will cloud when exposed to slightly elevated temperatures. This reversible phenomenon is normal, and is the mechanism by which TRANS-245 derives its efficacy within high-temperature cleaning systems. TRANS-245 performs best in alkaline processes operating at temperatures above 90° F (32 °C). As with any antifoam or defoamer, thorough testing should always be conducted to determine the suitability and compatibility of the antifoam with the foaming system and processing equipment.

TRANS-700 Series

This series of predominantly non-aqueous, oil-based, silicone-free defoamers was designed for foam control in coatings, adhesives, wastewater, and chemical manufacturing.

APPLICATION AND USAGE GUIDELINES

To control foam, the recommended method of application is to add the TRANS-700 series of defoamers directly to the foaming product or process. Each foaming problem is unique and requires different treatment levels of defoamer, therefore use only the minimum amount of defoamer required to control the foam. Trial testing will be necessary to optimize the amount of defoamer used in a given process. As with any antifoam or defoamer, thorough testing should always be conducted to determine the suitability and compatibility of the defoamer with the foaming system and processing equipment.
