PolyGone™ High-Performance Depolymerizer / Stripping Agents

PolyGone™ stripping agents are unique formulations that remove cured polysulfide (PRC) and silicone RTV sealants from metal, ceramic, and some plastic substrates. PolyGone works at room temperature and does not contain flammable, chlorinated or odorous solvents.

Both polysulfide and silicone RTV are difficult to remove completely since they actually bond into surface/substrate. PolyGone reacts chemically with the polymer and breaks it down (depolymerizes) so it can be rinsed away without damage to the surface/substrate. This depolymerization prevents re-deposition of the reaction by-products and allow for water rinsing.

PolyGone completely removes 100% of the sealant which offers significant advantages over other removal methods that require scraping and typically results in damage to the substrate. There are also products that try to “dissolve” the sealants but due to their inertness, this does not work.
