Paints cerium pigments

A paint grade of cerium sulfide has also been developed. The pigment has been evaluated in several coatings formulations such as automotive refinish (acrylic-isocyanate binders), general industrial solvent-based systems (polyester-melamine bin-... [Pg.40]

In comparison to organic pigments, cerium sulfide formulations have a high Per-soz level of hardness, coupled with good direct impact resistance. This produces very good gravel impact resistance. Chemical resistance (acid, base and solvent) has been evaluated in paint by the drop test. No specific problem was detected except for organic acids such as acetic acid. [Pg.41]

Paint grade cerium sulfide pigments exhibit very good durability in both the xenon test and outdoor exposure. In QUV-A testing, however, the humidity conditions of the experiment are too severe to be representative of outdoor exposure. [Pg.41]

Florida exposure has been evaluated (with a refinish acrylic-isocyanate formulation). Paint grade cerium sulfide outperforms cadmium sulfides, and is equivalent to that of lead pigments (Figure 4—14). In comparison with organic pigments, cerium sulfide paint grade also has a good durability. [Pg.41]

Cerium sulfide pigments are also good candidates for automotive paints, due to the IR reflectance properties of Cerium compounds (Figure 4—15). [Pg.41]
