Ultra-fine agalmatolite product and use thereof in paints

摘要

Obtaining a natural or synthetic agalmatolite containing a narrow and controlled particle distribution range, can be obtained by a high-energy million process associated to a high performance aerodynamic particle size analysis, the final use of this product being the paint industry, imparting texture, silky luster, fineness, opacity, wet scrub resistance and whiteness to the paint.

主权项

1. A composition of ultrafine agalmatolite comprising
an average particle diameter size in the range of 0.4 to 6 μm and a multimodal particle size distribution displaying a multimodal particle size distribution, when measured by a laser particle size analyzer, where there are at least two distinguishable components, and at least one of said distinguishable components corresponding to a fine fraction greater than 1 μm and another ultrafine fraction of the different component, whose particle size is less than 1 μm, also in a proportion that results in a flaxseed oil absorption value greater than 45 g of flaxseed oil/100 g of agalmatolite,whereinthe ultrafine component comprises a range of 15% to 80% by mass, andthe fine component comprises a range of 85% to 20% by mass.
