Valli Ventilated - Ventilato Quartz is obtained by micronisation of quartz sands with a high content of SiO2, being 96%.
All Valli Ventilated Quartz are produced with high efficiency technology, capable of ensuring consistency of the product in terms of particle granulometric distribution (quartz are checked with sieves and laser devices), chemical analysis (quartz are checked with XRF) and colorimetric analysis (finished products are checked with a colorimeter).
Valli Ventilated Quartz is highly appreciated for its whiteness and is available in multiple sizes, starting from 3 microns. Its hardness index on the Mohs scale is 7 and has a specific weight of 1500 kg per cubic meter.
It is used in the following fields: paints and varnishes, paint factories, abrasives, chemicals, mortars, floorings, restoration, refractory materials, wall cladding, bathroom fixtures, sealants, etc…
