puriss Grades
The puriss grades of Neuburg Siliceous Earth are even more fine than classic Sillitin. The grit portion (sieve residue) of these products - which is already very low - is further reduces the abrasivity of this product range, thus protecting processing equipment, such as mixers, tools and nozzles for airless spraying. Dispersal behavior in low-viscosity systems is also considerably improved. These effects are achieved through a final process after actual production. Puriss grades are therefore ideal for the manufacture of thin-walled articles and all applications requiring an excellent surface quality, whether this is for paints and varnishes, elastomers or plastics.
