What are Anti-Foams?

Anti Foams Case Study

Anti-Foams (aka defoamers) are chemical agents designed to control the wasteful formation of foam during industrial processes where they pose a wide range of serious issues. These include causing defects on surface coatings, preventing the efficient filling of containers and bacterial growth.

Anti-foams come in many different forms including mineral oil, silicone, natural organic and synthetic organic. Here at SNF Chemicals, we supply FLOFOAM anti-foaming agents in water immiscible, water dispersible, water based and concentrated formats. If you’d like us to recommend the most suitable anti-foam choice for your application, contact us here.

Defoamers are insoluble in the foaming medium and have surface active properties. Their low viscosity and facility to spread rapidly across foamy surfaces cause the air bubbles to rupture, resulting in the breakdown of surface foam.

One of our clients was a recycled aggregates company who found that washing a particular recycled aggregate resulted in a severe foaming issue; causing overflows from both the de-sander and the silt settler. These unsightly overflows caused slip hazards and time-consuming, labour-intensive clean downs. SNF’s anti-foams were used to effectively control the overflows and scum accumulation, meaning that the company saved time and money.
