109锌铬黄
产品名称：109锌铬黄
颜料索引号：CAS【37300-23-5】；P.Y.36
分子式：4ZnO·CrO3·3H2O
产品性质：
黄色粉末，耐光性较铅铬黄好，但遮盖力和着色力较低，微溶于水，在酸或碱中能完全溶解。具有阳极钝化作用，也具有阴极阻蚀剂作用，是一种重要的防锈颜料，也可用于调色。
应用范围：
主要用于涂料工业制造防锈底漆，对金属表面的防腐蚀性能良好。可用于航空、汽车底漆（如环氧富锌底漆）船舶涂料、军工设备防腐涂层，也用于塑料、油墨、橡胶等制品的着色。
注意事项：本产品应避免与有酸碱性或有还原性的物质混合使用。
本产品在运输、储存过程中，为了避免风化作用，应贮存在干燥的地方，同时避免气温的剧烈变化。
在使用本产品前，应先进行试验，以确保本产品能满足贵公司的要求。

Product Name: 109 Zinc Chromium Yellow
Color Index Number: CAS【37300-23-5】；P.Y.36
Molecular Formula: 4ZnO·CrO3·3H2O
Product properties:
Yellow powder, with better light resistance than lead chromium yellow, but slightly lower covering and coloring power, slightly soluble in water, and completely soluble in acid or alkali. It has anodic passivation effect and cathodic corrosion inhibitor effect, and is an important anti rust pigment, it can also be used for color adjustment.
Application Scope:
Mainly used in the manufacturing of anti rust primer for the paint industry, it has good anti-corrosion performance on metal surfaces. Can be used for aviation, automotive primer (such as epoxy zinc rich primer), ship coating, military equipment anti-corrosion coating, and also for coloring plastic, ink, rubber and other products.
Precautions: This product should not be mixed with acidic, alkaline, or reducing substances.To prevent efflorescence during transportation and storage, store in a dry place and avoid extreme temperature fluctuations.Prior to use, conduct tests to ensure the product meets your company's requirements.
