包膜中铬黄
产品名称：包膜中铬黄
颜料索引号：CAS【1344-37-2】；P.Y.34
分子式：PbCrO4·SiO2
产品性质：不溶于水、油和醋酸，溶于强碱和无机强酸。与硫化氢等还原物质略有反应，但颜料色泽变化不大。
主要特性：颜色纯正，制漆光泽度良好，同蓝色颜料可配成中绿色。是在中铬黄表面加入硅化合物，进行表面处理，以提高颜料的性能。
应用范围：涂料 可用于汽车底漆、工程机械涂层等对耐候性要求高的领域。
也可用于部分耐候性要求高的建筑涂料。
油墨 可用于高色彩、高遮盖需求的油墨。
塑料 可用于PVC、聚烯烃等需要耐热加工的塑料着色。
其它 可用于陶瓷油料、橡胶制品的着色等。
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。
表中所表明的指标值仅在我公司应用检测体系中测试所得，顾客需要根据产品应用的不同体系加以验证。耐光性1-8级，8级最好；耐侯性1-5级，5级最好；耐酸碱性1-5级，5级最好。

Product Name: Coated In Medium Chrome Yellow
Color Index Number: CAS [1344-37-2]; P.Y.34
Molecular Formula: PbCrO4·SiO2
Product properties: Insoluble in water, oil, and acetic acid; soluble in strong alkalis and inorganic strong acids. There is a slight reaction with reducing substances such as hydrogen sulfide, but the color of the pigment does not change much.
Main characteristics: Pure color, excellent paint glossiness, and can be mixed with blue pigments to form medium green. It is to add antimony compounds to the surface of medium chromium yellow for surface treatment to improve the performance of the pigment.
Application Scope:
Coatings Can be used in fields that require high weather resistance, such as automotive primers and engineering machinery coatings. It can also be used for some building coatings with high weather resistance requirements.
Inks Can be used for inks with high color and high coverage requirements.
Plastics Can be used for coloring PVC, polyolefin and other plastics that require heat-resistant processing.
Others Can be used for coloring ceramic oils, rubber products, etc.
Precautions: This product should not be mixed with acidic, alkaline, or reducing substances. Lightfastness: 1–8 grade (8 = best)；Weather Resistance: 1–5 grade (5 = best)；Acid/Alkali Resistance: 1–5 grade (5 = best).The stated values are based on our proprietary testing conditions. Customers must validate performance within their specific application systems.
