Silicon fluids, Silicon oil, and Silicon emulsion are among the most applicable polymeric fluids in various industries. Their resistance against temperature, electricity, moisture, and water and also the possibility of their dilution simply by water and their easy application have renders them suitable for the production of protective films and many other applications.  

The Silicon or polysiloxane polymer is composed of siloxane units (–R2Si – O – R2Si –), a colorless substance with a high resistance against temperature and electricity, which may appear like oil or rubber. Silicones have been the center of considerable attention during recent years as suitable substitutes for plastics, and are used in daily applications such as toys, mugs, and food storage containers as well as in industry as insulator, water stop, adhesive, sealant, washer, covering of electric constitutes etc. The silicon oil and silicon emulsion are among the silicon fluids. Silicon fluids are resistant against radiation, temperature, electricity, water and moist environments and thus, they are used as surface protective covers. Today, we can see their application as mold releasing agents and lubricants in plastic and rubber industry, as car polish and its surface film for protection against various weather conditions, cosmetic industry, textile industry for easier water evaporation to reduce the need for ironing etc. An emulsion is the mixture of two liquids and its stability depends on miscibility of the liquids. With respect to silicon emulsions, the silicon particles are distributed and dissolved in water by means of a mediator. Silicon emulsions are non-miscible silicones that have been evenly distributed in an aqueous environment by a surface active agent. 
Silicon emulsion is the silicon oil dissolved in an aqueous environment. The aim of silicon emulsion formulation is to simplify the process and to improve the final product. A stable silicon emulsion is produced by the use of emulsifiers in such a way that the emulsifier coats the surface of the silicon particles with the hydrophobic end of the emulsifier oriented toward the silicon particles and the hydrophilic end dissolved in water. Because of being a water based solution, the silicon emulsions do not contain dangerous by-products and are more environmentally friendly than other solvent based systems. Different components of a silicon emulsion (the carrier mainly being water, silicon particles, and the emulsifier) neither react with each other nor with the surface they are applied to. The silicon emulsion is more suitable for surface examination than silicon oil due to its relatively lower viscosity. 
The MANA silicon emulsions are temperature-resistant and non-toxic which make them suitable for industrial and commercial applications where the lubricants, jalasanjs, anti-static materials, and protective covers are required. Ease of application on the surface and simple preparation are some advantages of silicon emulsions. The silicon emulsions are categorized into anionic, cationic and non-ionic groups based on the type of emulsifying system. Most silicon emulsions are non-ionic and the cationic and anionic emulsions are selected depending on the application. The physical properties of these emulsions are varied according to the selection of different polymer for the adjustment of viscosity matching the intended application. Silicon emulsion with high viscosity and solidity are less costly as far as the transportation and deposition are concerned and must be diluted with water prior to the application.  
Silicon oil is a liquid polymeric siloxane with organic side chains mainly the polydimethylsiloxane. The most common silicone oil is a linear compound of polysiloxane whose side chains can slide easily on each other. Silicon oil is highly temperature resistant and highly flexible and is flowable at higher temperatures. Its extraordinary resistance to temperature and its lubrication property has put this substance at the center of substantial interest. Like all siloxanes, the backbone of the silicon oil consists of alternate repetition of oxygen atoms and silicon atoms in which each silicon atom can be conjugated by two different carbon based residues, mainly methyl groups. By substituting a small part of methyl groups with phenyl groups or those possessing active amino residues, the interaction of siloxane groups with other substances are affected which result in new properties. The viscosity of silicone oil ranges from 0.65 cs to 2000 kcs and, high viscosity of silicon oil can be reduced by emulsification. 
Silicon oil is mainly used as lubricant. It is very good electric insulator and also is non-flammable. Due to low surface tension, silicon oil can act as an anti-foaming agent and can be employed in industrial applications such as fermentation and distillation where huge amount of foam is problematic.
