SILAD 210 DEFOAMING AGENT IN SILICONE EMULSION 10%

Silad 210 Description — Foam Control Agent for Industrial Applications in Aqueous Systems

At Quimiconsult we offer Silad 210, an industrial antifoam formulated as a low-viscosity, water-based silicone emulsion, designed for effective foam control in a wide variety of industrial processes that use water-based systems: agrochemical formulations, industrial cleaning solutions, chemical manufacturing processes, the pulp and paper industry, textile processing, water-based paint and coating formulations, industrial water treatment, cutting fluids and metalworking processes, where foam formation reduces efficiency, tank capacity and operational quality. It is a homogeneous, stable, easy-to-handle and cost-effective foam control agent that excels in applications with nonionic and anionic surfactants, delivering superior performance under neutral, slightly alkaline or acidic pH conditions and effectively withstanding a wide range of process pH.

It comes as a homogeneous creamy white emulsion, with a viscosity of 1,000 to 3,000 cP at 25 °C, a 1% solution pH in the range of 3.50 to 4.50, water as the suitable diluent and a nonionic emulsifier (key to its compatibility with industrial surfactant systems). Supplying it as an aqueous emulsion, rather than pure silicone, makes it easy to incorporate evenly into the foaming system, improves the distribution of the active in the aqueous medium and allows precise dosing with standard metering pumps at typical starting concentrations of 50 to 500 ppm.

Silad 210 belongs to the category of polydimethylsiloxane (PDMS) antifoams emulsified in water with a nonionic emulsifier, one of the most established and effective technologies for foam control in industrial aqueous systems. Compared with organic antifoams based on vegetable oils, fatty acids or esters, silicone antifoams offer decisive advantages for industrial processes: greater potency per unit of mass, longer-lasting antifoam action over time, thermal stability suited to conventional industrial processes, broad compatibility with the surfactants used in industrial formulations and cleaning, and a safe handling profile under good industrial handling practices.

Important — choosing the right grade: Silad 210 is an industrial grade antifoam, formulated for industrial applications where there is no direct or indirect contact with food products intended for human or animal consumption. For applications involving food contact (food plants, meat processing, beverages, juices, preserves, washing of food products, supplements, CIP in food plants), the Silad 210 FG (Food Grade) version must be used: a kosher food grade product manufactured in a plant certified under the SQF scheme.

At Quimiconsult, located in San Nicolás de los Garza, Nuevo León, we distribute Silad 210 with nationwide coverage, application technical support, certificates of analysis for every lot, and up-to-date technical data sheets (TDS) and safety data sheets (HDS/SDS), serving agrochemical formulation plants, industrial cleaning solution manufacturers, paper mills, textile mills, water-based paint and coating formulators, chemical process plants, metalworking industries, industrial water treatment plants and production and development departments throughout Mexico.

The Silad Family at Quimiconsult — Industrial Grade and Food Grade

Quimiconsult offers two versions of Silad antifoam to cover every application according to the required regulatory grade:

• Silad 210 (industrial grade) — the product described on this page: silicone emulsion antifoam intended for non-food industrial applications. Ideal for agrochemical formulations, industrial chemical processes, the paper industry, textiles, paints and coatings, industrial water treatment, cutting fluids and industrial cleaning solutions without food contact. A more economical option than food grade when the end application does not require food certification.
• Silad 210 FG (Food Grade): silicone emulsion antifoam, food grade, kosher, manufactured in a plant certified under the SQF (Safe Quality Food) scheme recognized by GFSI. Intended for all applications with direct or indirect food contact: food plants, meat and poultry processing, beverages, juices, preserves, jams, dietary supplement manufacturing, condiments, washing of food products and CIP in food plants.

Key selection criterion: if your process involves any contact with food products, you must use Silad 210 FG. If the process is strictly industrial with no food contact, you can use standard Silad 210 to optimize cost. The price difference between the two versions is marginal compared with the regulatory risk of using industrial grade in food applications. When in doubt, using the FG version is always recommended to ensure regulatory compliance.

How Does Silad 210 Work?

Silicone emulsion antifoams such as Silad 210 work through a highly efficient, durable and selective physical mechanism that ruptures foam films.

The fine polydimethylsiloxane (PDMS) droplets released after the emulsion disperses migrate to the air-liquid interface of the foam bubbles, drawn by the low surface tension of silicone (~20 mN/m vs ~30-40 mN/m for foaming surfactant solutions). By inserting itself into the bubble's surfactant film (lamella), the silicone locally ruptures the film that kept the bubble stable. The lamella thins rapidly due to capillary forces until it collapses mechanically, releasing the trapped gas.

Because the silicone is not chemically consumed during this process, it remains available to suppress new foam formation in cascade for extended periods after the initial dose, which explains the longer-lasting effect and lower dosage of Silad 210 compared with organic antifoams. The nonionic emulsifier in Silad 210 avoids unfavorable interactions with the anionic surfactants common in industrial formulations, maintaining effectiveness in the presence of process detergents and surfactants, and the polydimethylsiloxane chain does not undergo significant hydrolysis under the acidic to slightly alkaline pH conditions typical of industrial processes.

Industrial Applications of Silad 210

Agrochemical Formulations

Silad 210 is widely used in agrochemical formulation as a manufacturing process antifoam (foam control during mixing, filling and packaging of emulsifiable concentrates, suspensions, wettable powders and solutions) and as a final-formulation antifoam incorporated into the agrochemical product to prevent excessive foaming when the product is diluted in the farmer's spray tank. Its compatibility with the nonionic and anionic surfactants typical of agrochemical formulations (such as nonylphenol ethoxylates, alcohol ethoxylates and sulfonates) makes it a standard component in this sector.

Recommendations for Use, Dosage and Incorporation

Pre-mixing: the emulsion should be mixed gently before use to ensure uniformity. In drums that have been standing for a long time, stir gently or recirculate before dosing.

Method of application: Silad 210 can be used as a concentrate (direct dosing) or diluted in water or process liquid (the recommended form for maximum cost-effectiveness and better distribution): mix 1 part Silad 210 with 3 to 10 parts of the selected diluent, stirring gently until a uniform mixture is obtained. Keep the dilution under continuous gentle agitation during intermediate storage to ensure uniformity.

Point of addition: to maximize cost-effectiveness, the antifoam should be pre-diluted and added continuously at a stage before foam forms (proactive, not reactive dosing). This practice prevents foam from forming rather than eliminating it once formed.

Suggested starting concentrations: 50 to 500 ppm of Silad 210 in the foaming system. Start with the lowest dose in the range (50-100 ppm) and adjust upward progressively until the desired foam control is achieved, optimizing dosage and cost. The exact concentration depends on the foaming intensity of the process, the type of surfactants present, temperature, pH and residence time.

Dosing equipment: standard diaphragm, peristaltic or piston metering pumps are suitable. For continuous dosing in process lines, flow-controlled injection systems help maintain a constant concentration.

Silad 210 Compatibility

Silad 210 is compatible with water and aqueous solutions in any proportion, nonionic and anionic surfactants at typical process concentrations, dilute organic and inorganic acids, moderate bases, organic and inorganic salts, auxiliary formulation surfactants, standard industrial additives, water-soluble polymers and most industrial process ingredients.

It requires special precautions with: cationic surfactants at high concentration (they can alter the stability of the nonionic emulsion — check the specific case), extreme temperatures during prolonged storage (excessive heat or freezing can cause reversible separation of the emulsion), strong oxidizing agents at high concentration (concentrated peroxide, highly concentrated hypochlorites), and very intense prolonged shear that may affect emulsion stability.

Storage, Handling and Shelf Life

To ensure product quality, the container must be tightly closed when not in use. Store at controlled room temperature (ideally 15-30 °C) and avoid prolonged exposure to extreme temperatures of heat (>40 °C sustained) or freezing, which can cause separation of the emulsion.

In case of separation due to exposure to extreme temperatures: if frozen, first thaw at room temperature; gently stir the contents to recombine the phases; use as usual. Reversible separation does not compromise product performance once homogenized.

The product's shelf life under proper storage conditions is typically 12 to 18 months from the date of manufacture, depending on the supplier's specification and the lot. The official expiration date is shown on the original container and on the lot's Certificate of Analysis.

Safety, Handling and Regulatory Considerations

Silad 210 is an industrial grade silicone emulsion with a well-characterized handling profile, recognized as a substance with a low hazard profile under normal industrial use conditions. Emulsified polydimethylsiloxane (PDMS) antifoams have a long history of safe use in industrial applications under good handling practices.

Recommended PPE: chemical safety goggles, industrial gloves (nitrile or equivalent), appropriate work clothing and work in areas with adequate ventilation.

Spill handling: Silad 210 spills are slippery and present a fall hazard. Contain with inert absorbents (vermiculite, sand, absorbent pads), collect and dispose of according to current waste legislation. Wash the area with water and detergent to remove residues.

Important regulatory consideration: Silad 210 is an industrial grade antifoam, not suitable for food contact. For applications with direct or indirect food contact (food plants, beverages, meat products, supplements, washing of food products, food CIP), Silad 210 FG must be used (food grade, kosher, manufactured in an SQF plant).

Every lot of Silad 210 comes with a Certificate of Analysis (CoA), technical data sheet (TDS) and safety data sheet (HDS/SDS) available for inclusion in operational records.
