There is provided a method for coating a molded resin article such as an automotive part, and improving its electrical conductivity by a high productivity procedure which avoids using an inorganic conductive primer. The substrate is coated with a composition containing a film-forming component and a specified nitrogen-containing compound and the coated surface is subjected to corona discharge treatment and is then optionally electrostatically coated.
Dihydronepetalactone, a minor natural constituent of the essential oil of catmints (
Nepeta
spp.) such as Nepeta cataria, has been identified as an effective insect repellent compound. Synthesis of dihydronepetalactone may be achieved by hydrogenation of nepetalactone, the major constituent of catmint essential oils. This compound, and compositions thereof, which also has fragrance properties, may be used commercially for its insect repellent properties.
