When selecting a coating for a surface exposed to constant direct sunlight, which property is especially important?
a.Low cost only
b.UV and color-retention resistance (fade resistance)
c.The fastest possible drying time
d.The lowest possible film thickness
Giải thích
Ultraviolet light degrades binders and pigments, so exterior coatings in full sun should have good UV resistance and fade-resistant pigments. 100% acrylic exterior paints are commonly specified for this reason. Matching the coating to the exposure is a core part of product selection.
