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.

1. PRODUCTION OF ULTRAFINE AGALMATOLITE AND APPLICATIONS THEREOF, characterized by the fact that the average particle diameter size is in the range of 0.4 to 11 μm and multimodal-type particle size distribution: displaying a multimodal particle size distribution, when measured by Cilas 1064, 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 35 g of flaxseed oil/100 g of agalmatolite.
