Silicones, known to chemists as polyorganosiloxanes, have a unique chemical structure of alternating silicon and oxygen atoms. This uniqueness has led people to formulate high performance speciality chemicals which perform outstanding functions. Aerol formulates various products based on these silicones that help industries to produce high quality products.
 

Aerol’s expertise is in the manufacture of Silicone Sprays, Silicone Defoamers/ Antifoams, Silicone Emulsions and Silicone Solutions. Aerol also produces a range of ‘Silicone-Free’ products that overcome certain limitations of Silicones in specific applications.
 

Further information is categorized into four parts, namely

Silicone & Silicone Free Sprays
Silicone Sprays are versatile, multi-use aerosol products used for various industrial applications such as releasing, lubricating, protection and polishing. Silicone Sprays are usually unparalleled in performance but have certain limitations. These limitations of Silicone Sprays are over come by Silicone Free Sprays that are proprietary products designed to eliminate the ill effects of Silicones.

Here is a brief description of Silicone & Silicone Free Sprays

Afra® Heavy Duty Silicone Sprays
Afra® Heavy Duty Silicone Sprays are a pressurized solution of Silicone Fluids and solvents. On spraying, the propellant and solvent evaporate, leaving behind a thin film of Silicone Fluid. These films of Silicone Fluids have several outstanding features and are listed below

• Wide serviceable temperature range from minus 40°C to 200°C (up to 300°C in some special grades), without decomposition or carbonization.


• Non-gumming, non-oxidizing, non-staining, non-toxic and chemically inert in nature.


• High Refractive index providing optical clarity and a high shine onto surfaces to which applied.


• Low Surface tension facilitates deep penetration and high surface wetting ability.


• Excellent lubrication for petroleum sensitive plastics & rubber, metals and synthetic materials.


• Highly water repellant, corrosion resistant and imparts protection against ill effects of moisture, weather and humidity.

Applications

• As a Mould Lubricant / Release Agent in the injection molding of Plastics and Rubber. They provide defect free and faithful reproductions from complicated moulds.


• As an Anti-spatter agent in welding operations.


• As a release agent in metallurgical molding/ casting, candle manufacturing and resin casting.


• As a Non-Stick agent on cutting blades of paper, plastic, adhesive tapes etc., gluing equipment in printing presses (press room and bindery) & plastic heat sealing equipment.


• As a non-toxic, non-staining, non-carbonizing, high and low temperature resistant lubricant for delicate mechanisms and components where friction takes place between non-metal and non-metal surface, non-metal to metal surface or metal to metal surface such as curtain runners, blinds, sliding doors & windows, tread mill belts, zippers of luggage, diving suits and tents, printer head guides, sewing needles-thread-work tables in high speed garment and leather production. In automobiles these grades may be used to maintain locks, hinges, telescopic antenna, seat rails, seat belt recoilers, wiper blades, battery terminals etc. They are also used to lubricate conveyors in food and pharmaceutical industries due to their non-toxicity.


• As a moisture / rust resistant protective coating on chrome plated automobile parts, delicate instruments, components & electrical assemblies and switch gear.


• As a polishing and finishing agent for plastic, rubber, polished/ painted wooden and steel surfaces such as auto tyres, rubber trims, dashboards, bumpers, TV & audio cabinets, plastic, wooden and steel furniture etc.

Note: Surfaces treated with Silicone spray will be resistant to the adhesion of paint, glue, ink and other coating materials. In such cases Afra® Heavy Duty Silicone Free Spray could be a useful option. Grades containing high solvent contents may adversely affect certain plastic and rubber surfaces, if prolonged contact is maintained. Such applications should be tested for compatibility.
