Control of Static Electricity on a Phonograph Record
A method of making phonograph records permanently anti-static is disclosed. Quaternary ammonium salts as a family of compounds were observed to be quite effective in reducing surface relativity, and vinyl plastic containing American Cyanamid's Catanac SN produced phonograph records which demonstrated practically complete absence of a static charge. A major quality improvement resulted from this process since static-free records do not attract damaging lint and dust particles.
