Abstract
A no base coat vehicle headlamp reflector can be improved with a plasma deposited layer of a siloxane material. The siloxane layer acts as an barrier layer formed directly on the vehicle reflector. The vehicle headlamp reflector with no base coat, but an barrier layer yields a resin lamp interior protected from upsets in the reflective layer and from outgasing condensate. The lamp reflector coated with plasma polymer of methanol yields a plastic lamp reflector resistant to condensation forming thereon, and resistant to attach by water vapor.
