Method of applying a varnish, including a solvent or solvent free, on a component, especially a vehicle headlight reflector

摘要

A method of applying a varnish, whether or not it includes a solvent, on a component, in particular a vehicle headlight reflector, comprises the following steps: (i) selecting a varnish having a viscosity at ambient temperature of about 500 to 2000 mPa.s, and a viscosity at the application temperature which is lower than about 200 mPa.s, with a viscosity which is substantially independent of variation in the temperature within the range of application; (ii) heating the surface of the component before the step of moistening the varnish at a selected temperature thetap1; (iii) heating the varnish at the moment of application to a selected temperature thetav; and (iv) during the spreading step, maintaining the component at a selected temperature thetap2 for a selected time tp2.
