  • Patent number: 5183845
    Abstract: A composition and process for protecting, preserving, and renewing surfaces, especially rubber and other natural and synthetic polymers, leather, and wood is disclosed. The emulsions of the present invention are applied to the polymer surfaces and by virtue of the composition, once applied, the emulsion will break causing the deposition of a uniform coating of treatment chemical. The treatment chemical is formulated to protect, renew and preserve the polymer surface being treated. The treatment composition comprises dimethylpolysiloxane fluid, an aminofunctional dimethylpolysiloxane, a wetting agent, an emulsifier pair, and an agent which causes the emulsion to break when applied to the surface. Each component contributes to the performance of the composition and facilitates the proper deposition of treatment chemical.
