  • Two-part aerosol composition for increasing the light reflectivity of an object
    Patent number: 5169558
    Abstract: A two-part system and method for increasing the reflex-reflectivity of a substrate is disclosed wherein a first aerosol dispensing means containing a first coating composition capable of forming a base coating on a substrate and a second aerosol dispensing means containing a second coating composition capable of imparting reflex-reflectivity to the base coating is employed. The first coating composition comprises a binder resin and a solvent in which the binder resin is dissolved and the second coating composition contains transparent microspheres having a particle size from about 45 to about 90 microns and a carrier in which the transparent microspheres are dispersible. The substrate is coated first with the first coating composition via aerosol means to form a base coating which is subsequently coated with the second coating to impart reflex-reflectivity to the base coating.
