Substrates, pigments

Chemical Composition. With few exceptions, inorganic pigments are oxides, sulfides, oxide hydroxides, silicates, sulfates, or carbonates (see Tables 3 and 4), and normally consist of single-component particles (e.g., red iron oxide, a-Fe203) with well defined crystal structures. However, mixed and substrate pigments consist of nonuniform or multicomponent particles. 

In the case of substrate pigments, at least one additional component (pigment or extender) is deposited onto a substrate (pigment or extender), preferably by a wet method. Weak, medium, or strong attractive forces develop between these pigment... 

Special substrate pigments include the aftertreated pigments and the core pigments. To produce aftertreated pigments the inorganic pigment particles are covered...

The purpose of a sunscreeri, be it a lotion for people or a coating for a car, is either to reflect or to absorb and dissipate UV energy before it reaches the substrate. Pigments such as zinc oxide reflect the energy, but, for a clear coating, this approach is impractical. The first commercial sunscreen available in lotion form was PABA (p-aminobenzoic...
