100% ANTIFOAM

Alstone Silicone Antifoams/Defoamers

A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. The terms anti-foam agent and defoamer are often used interchangeably. Strictly speaking, defoamers eliminate existing foam and anti-foamers prevent the formation of further foam.Silicone-based defoamers are polymers with silicon backbones. These might be delivered as an oil or a water based emulsion. The silicone compound consists of a hydrophobic silica dispersed in a silicone oil.Emulsifiers are added to ensure that the silicone spreads fast and well in the foaming medium. The silicone compound might also contain silicone glycols and other modified silicone fluids

OVERVIEW
Technical information
Enquiry

Silicone antifoam compounds are oily, viscous, opaque or slightly cloudy liquids. They are mostly used in systems containing little or no water. The compounds can be used neat or mixed with suitable formulation components such as surfactants.
Self-dispersing silicone antifoam agents are a combination of antifoam agent compounds with organic active agents and auxiliaries. They disperse spontaneously on contact with foaming formulations and show good compatibility and spreading properties.
Silicone antifoam emulsions are o/w emulsions of antifoam agent compounds with an active content of 5 to 50%. They are mainly used for water-borne formulations and applications.
Silicone antifoam powders are ideal for use in powder products, such as powder-form detergents.
Silicone fluids are characterized by good antifoam properties in water-free, non-polar systems. They are suitable for applications in which compatibility with other substances is not required.
