Foam control products—also referred to as antifoams, defoaming agents, and air release agents depending on their intended effect—are designed to mitigate or eliminate the production of unwanted foam during industrial operations and final product use. These compounds can be formulated in many ways to suit different application requirements, including with regard to antifoaming agent chemistry & compatibility, product properties (water dispersibility/insolubility, viscosity, temperature stability, solids content, etc.), and performance (flash knockdown, staying power, spreadability, etc.).
In certain applications, non-silicone foam control products are preferred due to concerns about silicones contributing to undesirable surface defects in dried films, deposition, etc. In recent history, silicones and their derivatives have also been subjected to shortages and price fluctuations, leading to increased focus on development and use of non-silicone alternatives in areas where silicone products are commonly accepted and utilized.
Need non-silicone antifoams and defoaming agents for your facility and operations? Crucible Chemical Company has got you covered. We have produced specialty chemicals for over 50 years, with a primary focus on antifoaming agents and defoamers. We offer a range of standard products as well as capabilities for custom formulations to satisfy standard and unique customer needs. Below, we highlight a selection of our non-silicone anti-foaming agent products.
Non-Silicone vs. Silicone Anti-Foaming Agents
Anti-foaming agents play a crucial role in controlling unwanted foam during industrial processes, but the choice between silicone and non-silicone formulations can significantly impact performance. Silicone-based defoaming agents are highly effective at breaking foam quickly and are widely used across coatings, adhesives, and wastewater applications. However, they can sometimes leave surface defects, cause fish-eyeing in paints, or be incompatible with sensitive formulations.
Non-silicone antifoaming agent solutions, on the other hand, offer excellent foam control without the risk of surface imperfections. They are especially valuable in applications where silicone contamination is undesirable or restricted. Non-silicone formulations can be tailored to specific systems, providing long-lasting performance in water-based inks, latex adhesives, paper processing, and other sensitive processes. Choosing the right type ensures optimal foam control while maintaining product quality and process efficiency.
Standard Non-Silicone Antifoam Products

Foamkill 608 — Foamkill 608 is suitable for dispersion paints, latex adhesives and water based inks, including materials that are sensitive to fish eyeing.
Foamkill 639 — Designed for latex paints and adhesives; also highly universal in defoaming agents applications, including white water slurries, pulp manufacturing, and monomer stripping
Foamkill 649 — A 100% active non-silicone antifoaming agent, completely emulsifiable and suitable for difficult foaming issues requiring “fisheye-free” properties. Commonly used in adhesives, paints and coatings, inks and graphic art materials, metalwork components, and paper.
Foamkill A-60 – This water-based defoamer is a non-toxic, APE-free emulsion that is highly effective as a deaerating agent and foam prevention agent in various paper and wastewater treatment applications.
Foamkill 4048 – This ready to use oil-based defoamer is formulated specifically for use in Kraft pulping, water-based paint, waste treatment and other industrial applications. It provides fast bubble break, persistent antifoaming and phase stability in the drum.
Foamkill SK-1 — This synthetic, non-silicone defoamer can be used as-is or mixed with petroleum oil or pre-thickened water. It is commonly used in water-based inks, paints & coatings, as well as textile wet processing.
Foamkill SFF-D — This non-silicone defoamer is specially formulated for extended performance in difficult foaming applications that require small addition quantities. It is ideal for use during the production of inks and graphic arts.
Foamkill 4078 – Foamkill 4078 is a 100% active, concentrated product for textile wet processing. It is a high strength product that can be used as-is or diluted with oil or further emulsified in water.
Foamkill SC-54 — This non-silicone foam control product is emulsifiable and compatible with synthetic or oil-based materials. It is suitable for use during the production of drawing or cutting fluids, which are commonly utilized in metalworking operations.
Foamkill VFN — This silicone-free foam control product was developed as a VOC-free alternative to traditional petroleum-based products used for water-based coatings, inks, and paints that need high compatibility.
Foamkill 660P — This organic defoamer demonstrates excellent efficiency, instant flash knockdown, and broad compatibility for different pH levels. It is often used during the protection of textiles and the processing of wastewater.
Foamkill 20 — This low-cost, general-purpose organic defoamer is used in both intermittent and continuous feed applications. It is an effective foam control solution for many wastewater processing operations.
Concentrated Non-Silicone Antifoam Products
These non-silicone foam control products are highly concentrated for use in severe-foaming systems. They can be further diluted for resale or direct use in more standard applications.
Foamkill FS-4 Concentrate— This all-organic, non-silicone foam control concentrate can be diluted with mineral oil. It is suitable for foaming applications in textile processing and pulp/paper applications.
Foamkill 2890 Concentrate — This non-silicone foam control concentrate can be used as-is or mixed with water and colloid thickeners for use in textile operations.
Foamkill DF-4 Concentrate — This synthetic foam control concentrate can be cut with oil or blended with water and thickener. It is used during the production of many products, including adhesives, coatings, inks, and textiles, and during the processing of water and wastewater.
Foamkill 652D Concentrate – This nonionic, inert defoamer concentrate is designed to be further compounded with petroleum distillates. The finished compound is a low cost, effective defoamer for general purpose paint and coatings applications.
