Aculon, Inc., a nanotechnology enabled performance coatings company, has completed the expansion of the company's research and production laboratory space. Started four months ago, the expansion of Aculons laboratory facility on Sorrento Valley Road in San Diego, Ca., effectively doubles the amount of laboratory space available for research and production of cutting edge surface modification treatments. The San Diego operation has been a major center for surface modification research since 2005, and since then has grown and expanded its activities to include both research and production of Aculon's proprietary technologies.
