Abstract
A chemical solution for use in cleaning and preserving vinyl materials, such as phonograph records, and metallic surfaces, such as the tape-engaging surfaces of read-write heads of audio and video tape recorders. The solution includes one or more solvents as carriers for a silicone, such as a dimethylsiloxane polymer. The silicone is in solution with a suitable organofunctional silane and with other intermediates, such as one or more alcohols, ethers, ketones and halogenated hydrocarbons. In other embodiments, the solution can be comprised of two or more solvents which serve as cleaners and preservatives.
Claims1
A solution for cleaning and preserving plastic and metallic surfaces comprising:
- a solvent including anhydrous isopropanol;
- a vinyl benzylamine functional silane;
- halogenated hydrocarbons;
- and a silicone including dimethylsiloxane polymer in solution with the solvent and the silane, the silane and the silicone being operable to form a protective layer on a surface when the solution is applied thereto, said solvent being in the solution at a volume of approximately 775 parts per 1000, said silane being in the solution at a volume of approximately 10 parts per 1000, said halogenated hydrocarbons being in the solution at a volume of approximately 200 parts per 1000, and said silicone being in said solution at a volume of approximately 15 parts per 1000.
