ABSTRACT:
Disclosed is a yellow incandescent bugfoiler pigment coating comprising a fine-ground blend of praseodymium doped zirconium silicate and silica. This cadmium-free blend is applied electrostatically in three coats to the interior of a bulb to diffuse the light and block the emitted UV wavelengths. The color of the blend will intensify with increasing heat and return to its initial yellow color upon cooling.
