Silicone Fluids

Silicone Fluid

Silicones are a family of inorganic polymers with Si – O – Si linkage, commonly known as poly(siloxanes). Most petroleum polymers have carbon atoms joined together forming polymeric chain while silicones have silicone atoms joined together with oxygen in between. It covers wide range of products with variety in its applications. One can notice difference  between Silicon and Silicones, as Silicon is a most common element in the earth’s crust and Silicones are synthesized inorganic polymers made out of it. Silicone fluids are generally colorless transparent liquids. They exhibit excellent resistance to heat, cold, and moisture. There is also little viscosity change in silicone fluids over a wide temperature range, and they have outstanding electrical properties. In addition, they are notable for their characteristics of mold-releasability, water repellency, lubricity, and defoaming properties

Features of silicone fluid

Silicones are available in wide range of properties from volatile liquids to soft gels, hard material. Silicones products provide solutions to ordinary and extraordinary problems. They make material stronger, more stable, more resilient, more aesthetically pleasing, easier to use or apply and longer lasting. They help materials perform to the high standards to cope up with consumers expectations. Silicones, being versatile, are high-performance materials which bring real benefits to a wide range of applications. This is primarily because of unusual properties such as thermal and oxidative stability & mild dependence of physical properties on temperature, high degree of chemical inertness, resistance to weathering, good dielectric strength and low surface tension.

Silicones have following physical and chemical characteristics

  • Outstanding weathering and aging resistance
  • Thermostability
  • High water repellency
  • Extremely strong adhesion qualities
  • Can withstand long-term exposure to the atmosphere
  • Resistance to UV and IR radiation
  • Extremely low volatility
  • Inert (non-reactive with most materials)
  • Chemical resistance
  • Long-term elasticity, pliability and flexibility
  • Excellent electrical insulation
  • Tensile strength
  • Anti-foaming properties
  • Microbial resistance

Uses for silicone fluids

Silicone oil is used in almost all sectors of life few representative examples are as follows

  • Additive for cosmetics, personal care, health care products, pharmaceuticals
  • Lubricating oil for various mechanical parts
  • Additive and release agent in resins, elastomers, rubbers, polymers etc
  • Shinning agent for automobile, furniture polish, textile finish
  • Industrial cleaners, release agents for various industrial products
  • In cooking oil as deep frying
  • Paint, coating component

Silicone Surfactant

Silicone Surfactants Surface active agents, or surfactants, are products that, at very low concentrations, markedly reduce the interfacial surface tension of liquid-gas, liquid-liquid and liquid-solid interfaces. Depending upon their behavior, at such interfaces surfactants can function as wetting agents, emulsifiers, detergents, dispersants, foaming agents, solubilizers, etc. and are therefore useful in many industrial applications.

Surfactants have two distinct components in their molecular structure: a hydrophobic (water-repelling) portion and a hydrophilic (water-attracting) portion. The combination of these distinct hydrophobic and hydrophilic parts within a single molecule accounts for the reduced surface tension and the other important properties that are characteristic of this group of chemical compounds.

Traditional surfactants have carbon chains as the hydrophobic portion of the molecule. The hydrophile that is added to the carbon chain will determine the solubility and the general class of surface active agents as anionic, cationic, nonionic or amphoteric.

A series of surfactants which are based upon silicone as a hydrophobe that contain other functional groups, similar to those seen in traditional surfactants have been and continue to be developed. In some instances, silicone is incorporated into a surface-active agent, with a polyoxyalkylene portion of the molecule and or a hydrocarbon portion of the molecule. As will become clear, this results in several unique properties of the surfactant. Historically, silicone compounds have been available as water insoluble oily materials.

Supreme Silicones is specializes in the creation of unique silicone-based surfactants, where the hydrophobic portion of the surfactant comprises a siloxane backbone. By adding various organic or inorganic functional groups, which by their nature may be nonionic, anionic, cationic or amphoteric (then referred to as organo-silicone compounds) to various siloxane chains or networks, Supreme Silicones can offer a truly endless variety of products with unique and desirable properties.


Silicone Surfactants are used as a Super Wetting and Spreading Agent, which have a low molecular weight, nonionic, developed to improve the wetting, spreading and penetration of agricultural chemicals.

As  Super wetting Agent reduces surface tension below 22 dynes/cm, which produces very rapid wetting and spreading on hard-to-wet surfaces such as waxy leaves. Thus, complete coverage can be achieved with herbicides, insecticides, fungicides and other agricultural chemicals. It may be used as a formulation ingredient in pesticide products, or as a tank-mix adjuvant for foliar applied chemicals

Silicone surfactant, in addition to the rapid wetting and spreading action, also greatly increases the uptake of chemicals into plant tissues.

Potential Applications

Silicone Surfactant adjuvant has been used successfully in spray applications globally.


Agriculture : As wetting agent enhances performance of herbicides and pesticides

by dramatically reducing the product’s surface tension, results in better spread and

penetration of herbicides on the targeted leaves. This improved efficacy and to

minimize the amount of the chemicals needed.

Inks and Coatings: Provides better slip, improved mar resistance, better levelling

and foam control. Effective at very low concentrations hence are cost effective.

Textiles: Provide defoaming, lubrication, final product’s softness, feel, wear ability,

versatility and improved processing during the manufacturing stage.

Pulp and Paper: Improve various defoaming, drainage and better release. Also

increases softness, absorbance or repellence of final products.

Personal Care : Improved softness, shine, conditioning, detangling and

emollience. Also used as emulsifiers for creams and sun care products to

improve stability and efficacy aesthetic delivery.

Leather : Improve both natural and synthetic leather’s feel, softness, durability,

abrasion resistance and resistance to soiling.

Automobile : Improve gloss, shine and beading to various products.

Oil and Gas : As organic demulsifier. As processing aids in many applications.

Polyurethane Foam : As stabilizers for the polyurethane foam industry
