Understanding Lithopone B301 & B311 Key Manufacturers and Applications

Lithopone, a white pigment composed of zinc sulfide and barium sulfate, is widely used in various industries due to its excellent opacity, durability, and non-toxic nature. Among its several grades, Lithopone B301 and B311 are particularly noteworthy. These specific types are prized for their unique properties and have significant applications in coatings, plastics, rubber, and other materials.

Key Characteristics of Lithopone B301 and B311

Lithopone B301 is characterized by its high whiteness, excellent lightfastness, and durability, making it ideal for paints and coatings. It provides superior opacity and a smooth finish, making it a preferred choice for high-quality products. On the other hand, Lithopone B311 offers comparable performance with slightly different particle size distributions. This can result in varying degrees of brightness and opacity, which are crucial factors in specific applications.

Both grades are known for their ability to withstand harsh environmental conditions, which adds to their appeal in outdoor applications. Additionally, being non-toxic, they present a safer alternative to some traditional pigments, aligning with the increasing demand for environmentally friendly products.
