Commercial Successes

Commercial success is synonymous with our mission. Technology developed by A. A. Parker has been used to commercialize several products, a few of which are highlighted here:


  • Titanium Musical Instrument StringsTM and Surface Treatment Products by Rohrbacher Technologies LLC
"Titanium Acoustic Guitar Strings" represent one of the most unusual musical instrument product innovations in more than 100 years. By minimizing the galvanic couple between core and windings, this patented application of surface chemistry "cuts to the core" of the problem - it slows or eliminates corrosion, and increases longevity by orders of magnitude when compared to conventional strings.

  • Organosilane Surface Treated Musical Instrument Strings (U.S. Patent 7,476,791)
    •

This invention features a near-monolayer organosilane surface treatment that forms a moisture-resistant chemical bond with metallic strings. Unlike conventional "coatings" that are used with many string products, the organosilane's contribution to the mass of a string is negligible. This innovation translates to corrosion protection with acoustic transparency. Organosilane Surface Treated Titanium Acoustic Guitar StringsTM are available at www.rohrtech.com

  • Polyolefin Plastisol Adhesive
Polyolefin plastisol adhesive technology (U.S. Patent 7,285,583 & 7,501,468); developed by A. A. Parker together with W. C. Stumphauzer, and commercialized by the Liquid Polymer Corporation.   www.liquamelt.com
