Silicone Spray is mainly used for releasing plastic molded articles from their molds and dies during the injection molding process. These Mold Release Silicone Sprays provide faithful and clean reproduction of molded articles. They are commonly used to release articles such as TV and audio system cabinets, pens, automobile components, computer key boards and similar plastic parts. They are also used to release Resin, PU, Metal and Wax based articles in certain cases.
Certain special grade of Silicone spray are formulated for release of molten yarn from spinnerets in production of synthetic fiber. They are often known as Spinnerette Spray.
Afra® Heavy Duty Silicone Free Spray
It is a pressurized solution of proprietary ingredients and solvents. On spraying, the propellant and solvent evaporate, leaving behind a thin film of active ingredients. These films of actives act as release agents in the Injection molding operations of plastics and also as an anti-spatter agent in welding operations. These grades have been specifically designed for applications where the presence of films of silicone fluids is undesirable.
• Free from chlorinated solvents, Class I & Class II Ozone Depleting substances.
• Special propellant gas with optimized propane-butane ratio and free from un-saturates.
• Unique combination of ingredients and valve design enables a fine mist spray for optimized application on molds.
• Wide choice of dry, semi-dry and oily actives deposition on mold.
• Most Grades are Non-toxic and generally odorless. Suitable for incidental food contact.
• Use of plastic safe solvent enhances compatibility with most plastic substrates.
Applications:• Designed for use as Mould Release Agent s for most injection moolded plastics and organic rubbers such as EPDM, Neoprene, Viton, Nitrile etc.
