| Silicone Antifoams
Gayatri Polychem silicon defoamers and silicon antifoams are high performance silicone based products containing non- ionic surfactants and functional additives. Foam formation is the result of dissolved molecules in a liquid. The dissolved molecules alter the surface tension of the liquid, and can be viewed as surface active agents (surfactants). The surfactants can be non-ionic, cationic, anionic, or amphoteric. The liquid can be either aqueous, non-aqueous, or both (some industrial systems may contain dissolved organics which require special consideration). Different surfactants will generate different types of silicone antifoams, antifoam emulsion, silicone antifoam emulsion and foam stability. When agitated, bubbles will form, which will immediately encounter gravitational effects pulling liquid along the bubble walls back down into the liquid beneath the bubble. A simplified picture of a bubble can be described as spherical, having both an outer wall and inner wall. When the surface tension is high enough, bubble formation becomes more rigid and stable. If a bubble is subjected to mechanical agitation, bubbles caused by entrained air, would form very stable lamellar structures. The Marangoni effect is a major stabilizing factor in foam, and is driven by osmotic pressure. In some cases, the aqueous liquid is being pulled through the bubbles walls creating regions of low and high surfactant concentrations, which sets up a gradient along the bubbles surface. The gradient would pump liquid back onto the bubble walls, where this phenomenon is referred to as a surface transport. The bulk viscosity also contributed to foam stability. As the viscosity of liquids increase, entrained air, now a bubble, can be trapped below the liquid’s surface. Increasing viscosity of the system also reduces the coalescence capability of smaller bubbles merging to become larger bubbles. If the bubbles become large enough (increasing the diameter), bubble stability decreases. GP SD 15 EMULSION Milky white color, Silicone Antifoams - GP SD 15 EMULSION is a concentrated emulsion that can be diluted with water. Formulated by modifying quality tested chemicals under the strict supervision of our skilled pharmacists and biotechnologists, these products are in compliance with the intentional quality standards. In addition, we offer customization services and on-time product delivery for our esteemed clients. GP SD 40 EMULSION Silicone Antifoams - GP SD 40 EMULSION is milky white emulsion that is a shear stable deformer for alkaline conditions. It is quality tested on several parameters, such as purity, composition, effectiveness and stability. In addition, our products are appreciated by our clients for outstanding flexibility, longer applicability, proper pH value, eco friendliness and accurate composition. We also offer customizations services as per the clients’ requirements. GP SD 50 EMULSION We have an expertise in offering milky white color emulsion, Silicone Antifoams GP SD 50 EMULSION, which are concentrated emulsions to be diluted with water. They are nature-friendly antifoams and are available at low cost for several general purpose applications. These can be added to various dry products, such as instant powder, detergents and fertilizers to prevent foaming. Powder Antifoams Powder Antifoams GP SD P 60 comprises of silicone antifoam that is absorbed on an inert powder, which then stays in a free-flowing concentrated form. It is an easily combined with other powdered formulations to provide foam control, when the material is dipped in water. They find applications in detergent, agricultural, pesticide and many more industries. GP SD 30 EMULSION We are engaged in offering Silicone Deformer - GP SD 30 EMULSION prepared by using advanced technologies ensures maximum effectiveness. It is rigorously checked by our quality controllers on several parameters to ensure flawless product delivery. These deformers are used in aqueous solutions, prevent foaming and also help in maintaining the quantity in the reaction vessel.

| Gayatri Polychem silicone fluids, Dimethyl Silicone Fluids, Dimethyl Polysiloxanes silicone fluids are water clear liquids which are available in viscosity ranging from 10 Cst - 60,000 Cst. Their distinguishing features result from their molecular structure. Silicone fluids are Dimethyl polysiloxanes with unbranched chains consisting of alternate silicon & oxygen atoms, their free valencies being saturated with Methyl groups, whereas carbon chains of organic materials are rather sensitive to external influences, the stability of the organic Si-O bonds corresponds in many regards to the chemically inert behaviour of mineral Silicates.
