Lead paint or lead-based paint is paint containing lead. As pigment, lead (II) chromate (Pb Cr O. 3, "white lead") are the most common forms. [1] . Lead is added to paint to accelerate drying, increase durability, maintain a fresh appearance, and resist moisture that causes corrosion.
Lead compounds are primarily added to solvent-based paints, such as enamel (gloss) paints. The lead content of paint can range from less than 90 ppm (0.009% by weight) from background impurities to over 100,000 ppm (10% by weight).
1 Ιαν 2023 · Lead-based pigments are one of the main sources of lead in paint formulations. They are commonly used to create color in paint, gloss, anti-corrosion properties, and as a filler in paints; for example, red lead (Pb 3 O 4 ) is a pigment with anti-corrosion properties, but its use is limited.
Lead compounds also may be added to enamel (oil-based) paints for use as driers (sometimes called drying agents or catalysts). Enamel paints dry to a hard and smooth surface through a process that involves chemical reactions in which paint ingredients called binders polymerize and crosslink.
