Application:

Iron oxide yellow pigment is suitable for the coloring of plastic products and rubber products, such as automobile inner tubes, airplane inner tubes, bicycle inner tubes, etc.

Iron oxide yellow pigment can also be used for coloring paper and leather.

Iron oxide yellow has good dispersibility, stable storage, good compatibility with other components in the application system, and can enhance the paint's anti-rust and anti-ultraviolet properties;

Paint formula reference pigment amount: primer 20-30%; blend paint 15-25%; enamel paint 15-25% (excluding extender pigments)

Water-based paint: configure the appropriate amount according to the color.

Inspection standard of iron oxide yellow

Iron oxide yellow is a kind of chemical pigment commonly used in the industrial industry. Its products have many strong use properties. However, to ensure the performance of these useful properties, we need to carry out strict inspections on its related products and raw materials to determine product quality.

1. The iron oxide yellow products shall be inspected by the quality inspection department of the manufacturer to ensure that the quality of all iron oxide yellow products manufactured to meet the technical requirements of this standard. Each batch of iron oxide yellow products shall be accompanied by a product grade certificate;

2. In the technical indicators of iron oxide yellow products, "iron content", "volatile matter at 105 degrees Celsius", "water-soluble matter", "water-soluble chloride and sulfate", "sieve residue", "ph value of water suspension" Nine items such as ", "oil absorption", "color", and "relative tinting strength" are considered as factory inspection items. Each batch of products shall be inspected according to the test methods specified in this standard one by one after leaving the factory;

3. In the technical indicators of iron oxide yellow products, the four items: "pH of water extract", "lead chromate", "total calcium", and "the existence of organic coloring matter" shall be inspected quarterly according to the test method specified in this standard once.
