DESCRIPTION: PolyGone 505 is a high performance silicone sealant depolymerizer / emulsifier designed to remove cured silicone and other sealants from a variety of surfaces. Silicone has numerous applications including aviation, medical, potting removal, electronics, aerospace, marine, household, aquarium building & repair, dispensing equipment, telescope repair and microscope repair to name a few. Specific aviation uses include removal of silicone from turbine stators, thrust reversers and other engine components.
CHEMISTRY: PolyGone 505 is a proprietary formulation designed to penetrate, break down, and emulsify tenacious sealants. Once broken down, the sealant is suspended to prevent re-deposition and enable easy rinsing.
APPLICATION: PolyGone 505 is intended for use at room temperature (68°F-80°F). It may be continuously sprayed or used in immersion-based cleaning systems. Heat (120ºF/49ºC) and/or gentle agitation, including ultrasonic, is not necessary but significantly enhances performance. The agitation removes the digested sealant and exposes underlying layers to fresh PolyGone 505. However, do not use a sparging system, as this will quickly deactivate the emulsifier. PolyGone 505 must be used at full strength. Dilution and/or excessive heat, above 120ºF will deteriorate the emulsifier. RPM Technology recommends using PolyGone 505 in a well-ventilated area and in a covered cleaning apparatus to prevent product evaporation.
RINSE: PolyGone 505 is water-soluble. Although water may be used to rinse the product, rinsing with a mild cleaner such as eOx®, also available from RPM Technology, followed by pure water will improve removal of all residues. An emulsifier will improve rinsing via a “sheeting” effect, reduce sealant re-deposition, and reduce water usage. In cases where water is not preferred, a compatible solvent such as IPA or acetone may be used.
COMPATIBILITY: PolyGone 505 is metal-friendly. The formulation is non-ionic and non-reactive. Metals such as Cu, Fe, Al, Zn, and Ti have been tested with PolyGone 505 with no detected metal loss. However, PolyGone 505 attacks many types of polymers and plastics. Polyvinyl chloride (PVC), polyvinyl alcohol, and similar plastics should not be treated with PolyGone 505. Many elastomers are also not recommended. RPM Technology recommends the following plastics for application and storage, Polypropylene, Poly Olefin, Polyethylene (low and high density), Teflon, and Butyl Rubber. Testing is necessary to demonstrate full compatibility.
PPE: Recommend personal protective equipment (PPE) includes safety glasses/goggles and nitrile or butyl rubber gloves. Aprons may be used to protect clothing. Do not use gloves made from latex or vinyl.
TOXICITY: PolyGone 505 contains a blend of polar organics. PolyGone 505 has a low inherent toxicity and at diluted levels, is essentially non-toxic to aquatic life. The material is readily biodegradable and does not bio-accumulate.
STORAGE: PolyGone 505 must be stored in a cool and dry environment away from light and incompatible materials. The recommended storage temperature is between 50ºF-80ºF (10ºC-27ºC). Under these conditions, unopened containers of PolyGone 505 have a 1-year shelf life.
DISPOSAL: PolyGone contains no halogenated, reactive, or other EPA regulated components. Conformance with Federal, State, and Local disposal regulations is required. Diluted PolyGone can be disposed of by discharge to a sewage treatment plant with prior approval. Used PolyGone may need to be disposed of as organic solvent waste depending on the sealants and contaminates removed. PolyGone has a high BTU value and waste can be managed through a fuels-blending program.
AVAILABILITY: PolyGone 505 is available in individual poly gallons, 4×1 gallon cases, and 55-gallon steel drums.
