SagTex Industrial & Textile Antifoams

SagTex DSA silicone antifoam is a medium viscosity, highly potent antifoam emulsion that offers excellent foam control as well as excellent compatibility in a variety of surfactant concentrates and foaming systems. Compared to common silicone defoamers, it offers exceptional foam knockdown and durability, and greater compatibility in difficult surfactant systems, e.g., such as those rich in solvents and/or electrolytes.

KEY FEATURES AND TYPICAL BENEFITS

• High antifoam efficiency in surfactant-rich systems
• Rapid foam knockdown
• Excellent foam control at temperatures up to 95°C (203°F)
• Long-term foam inhibition
• Easy dispersion in all foam systems
• Easy dispersion in hard water
• Long durability in acid and alkaline conditions
• No oily spots or lumps when diluted with water
• Compatibility with a variety of surfactant concentrates

POTENTIAL APPLICATIONS

• TEXTILE PROCESSES
• Sizing
• Scouring
• Printing
• Finishing

PRODUCT USAGE GUIDELINES
SagTex DSA silicone antifoam is a medium viscosity emulsion that can be easily transferred from its original package using piston pumps. Centrifugal pumps are not recommended, as they risk destabilizing, and in extreme cases, separating the emulsion. In low viscosity formulations, preliminary stabilityand compatibility studies must be conducted prior to formulation design.

If SagTex DSA silicone antifoam is intended to be used in surfactant concentrates (primarily surfactants, water and solvent), it is recommended that the product be dosed in as received, i.e., without any predilution. Following its addition, carry out slow to moderate mixing to ensure complete and homogenous dispersion of the antifoam. Typical levels of use range between 0.1 and 0.5% depending on the formulation and the degree of foam control required. 
For process applications, we recommend prediluting SagTex DSA silicone antifoam with cold water in a ratio of 1:1 to 1:10. For high dilutions level, care must be taken to ensure stability of the dilution. Stability can be extended by adding small amounts of a suitable thickening agent, e.g., xantham gum or polyacrylates. Commercial biocides(a) containing 2-Methyl-4 Isothiazolin-3 ones and/or 2-Bromo-2-nitro-1,3-propanediol are very effective in this type of product.A suggested starting concentration is typically between 0.1 and 2%, but this will vary depending on the severity of the foaming problem.(a) Biocides must be used in accordance with FIFRA regulations and manufacturer’s guidelines.

SagTex PhD silicone foam control agent is a high-performance antifoam emulsion desgined for multiple uses in the textile industry. The product typically offers very good initial foam knockdown and excellent durability at concentrations less than half that of competitive silicone antifoams. Additionally, SagTex PhD silicone antifoam gives a homogeneous dilution in water or bath formulations with no oiling or agglomerates.

Key Features & Typical Benefits

• Long durability in acidic or alkaline conditions
• Outstanding durability at low add-on levels
• Effective performance at significantly lower use levels than competitiv antifoams.
• Excellent foam control at ambient and evelated temperatures
• Rapid foam knockdown
• No oily spots or agglomerates when diluted with water
• Easily dispersed in hard water.

How to Use
SagTex PhD silicone foam control agent is a medium viscosity emulsion that can be easily transferred from its original package using piston pumps. Centrifugal pumps are not recommended, as they risk destabilizing, and in extreme cases, seperating the emulsion. In low viscosity formulations, preliminary stability and compatibility studies must be conducted prior to formulation design.

For process application, we recomment prediluting SagTex PhD silicon foam control agent with cold water (less than 18 °C) in a ration of 1:1 to 1:20. If the diluted SagTex PhD emulsion will be stored before use, then care must be taken to ensure stability of the dilution. Stability can be extended by adding small amounts of a suitable thinkening agent, such as xanthan gum or polyacrylates, to the diluting water. Commercial biocides containing 2-Methyl-4Isothiazolin-3 one and / or  2-Bromo-2-nitro-1,3-propanediol are very effective in this type of product.

A suggested starting concentration is typically between 0.1 and 2 percent, but this will vary depending on the severity of the foaming problem.

SAG 638 antifoam emulsion is an excellent candidate to consider for general purpose foam control in aqueous systems.SAG 638 antifoam emulsion excels in applications requiring excellent knock down and durability. Remarkably small concentrations can sharply reduce the foam created, which can cut down the processing time and potentially permit maximum capacity production
KEY FEATURES AND TYPICAL BENEFITS.

• Outstanding and quick foam knockdown.
• excellent durability in both non-ionic and anionic surfactant systems.
• long lasting antifoam performance in acidic and alkaline conditions.
• good emulsion stabily.
• readilty dispersible in the foaming media.

POTENTIAL APPLICATIONS

• foam control in textile pre-treatment processes and textile print pastes.
• textile sizing and scouring agents
• acrylic latexes and thickners used for textile and nonwovens.
• other chemicals and chemical processes requiring foam control.

• Production Capacity: NA

Sagtex JSA foam control agent is a 100% active, specially formulated antifoam composition. This product has been developed to impart low-foaming characteristics to clear, high-actives, scour surfactant concentrate formulations. Sagtex JSA foam control agent will not separate from nonionic scour surfactant concentrates that contain less than 15% water. The resulting scour concentrate, when diluted to use concentration, will be low foaming over the entire jet scour cycle. Best of all, Sagtex JSA, foam control agent is a free-rinsing antifoam and therefore will not cause fabric spotting. 

Key Features and Benefits

• High efficiency foam control agent for jet scour applications
• Forms clear, stable concentrates if water concentration is less than 15%
• Free- rinsing composition, will not cause fabric spotting
