Question 1

What is lead chrome yellow pigment?

Accepted Answer

Lead chrome yellow (C.I. Pigment Yellow 34) is an inorganic yellow pigment composed primarily of lead chromate (PbCrO₄) and lead sulfate. It offers high hiding power, excellent tinting strength, and good heat resistance up to 260℃, making it widely used in industrial coatings, plastics, and printing inks.

Question 2

What are the applications of chrome yellow?

Accepted Answer

Chrome yellow is widely used in industrial coatings, architectural coatings, injection molding plastics, blow molding, screen printing inks, and offset printing inks. Coated grades offer enhanced weather resistance for exterior applications.

Question 3

What is the difference between regular and coated chrome yellow?

Accepted Answer

Regular chrome yellow offers standard lightfastness (level 2-5) and heat resistance (200-220℃). Silica-coated chrome yellow (EterYellow 5100-5400 series) features a protective SiO₂ layer that improves weather resistance to level 3-4, increases heat resistance to 240-260℃, and provides better dispersion in resin systems.
