Abstract
A venetian blind slat or coil of venetian blind slat substrate, such as aluminum, is first coated with a conductive primer. An anti-static conductive coated is applied thereover. The resultant coated finished blind slat and its associated spaced horizontal slats have sufficient conductivity to resist airborne dust particle accumulation with reductions in dust accumulation of from 36% to about 82% being attained, as compared to colored paint insulative coating on standard venetian blinds. An inorganic, inert conductive additive such as stannous oxide is employed in the anti-static conductive coating, resulting in coating conductivities of less than 10.sup.6 ohms per square and, in a preferred embodiment, from about 10 ohms per square to 10.sup.5 ohms per square.
