Engineered inorganic white pigment — factory-direct, customizable milling & packaging.
We concentrate on production consistency and service: every batch includes QC Particle Size report, COA on request, and tailored packing (25kg kraft / 500kg big-bag).
Technical support for formulators (dispersion trials, milling parameters) is available.
Lithopone B311 is developed for applications that require high hiding power with controlled tinting strength and improved dispersibility. Compared with standard lithopone grades, B311 emphasizes batch-to-batch consistency and formulation support for rapid scale-up.
Available in special-milled versions for low-tinting applications
Lithopone B311 is mainly applied in various high-end indoor and outdoor coatings, interior and exterior wall latex paints, industrial coatings, powder coatings, as well as in fields such as plastics, rubber, ink, leather, and paper production.
The product is packaged in a composite bag with inner plastic and outer woven material.
The net weight is 25 kilograms per bag.

Lithopone B311 is safe, non-toxic and harmless. It is white powder in appearance. During transportation, it should be protected from moisture. When stored, it should be placed in a cool, ventilated and dry place.
Note: The data contained here are based on our current knowledge and experience. It is the responsibility of user to test our products before the final application.
B311 is optimized for tighter particle size distribution and tailored milling options to reduce gloss variability and improve dispersion stability — especially helpful for high-solid coatings and masterbatches.
Yes — small sample packs and technical assistance for dispersion trials are available. Contact our technical team to arrange on-site or virtual formulation support.
Standard 25 kg bags, 500 kg big-bags, and custom packing. Lead times depend on order size and country — contact sales for current ETAs.
