SILLITIN / SILLIKOLLOID Neuburg Siliceous Earth
SILLITIN / SILLIKOLLOID Neuburg Siliceous Earth
Neuburg Siliceous Earth is a natural combination of crypto-crystalline and amorphous silica and lamellar kaolinite. These two minerals form a loose mixture impossible to be separated by physical methods. As a result of natural aging, the silica portion exhibits a round grain shape and consists of aggregated primary particles of about 200 nm diameter. This created a unique particle structure
The SILLITIN and SILLIKOLLOID line is the natural, untreated Neuberg Siliceous Earth , separated to the different particle sizes and color grades.
The SILLITIN and SILLIKOLLOID Puriss products are significantly finer grades. The extremely low residue of > 40 µm is further reduced in comparison with standard Sillitin. This also reduces the abrasion effect of this product series and protects processing equipment like mixers, tools and airless spray nozzles. The dispersion properties in low-viscosity systems are also greatly improved. These effects are achieved in a process after the usual processing steps. Puriss products are therefore ideal for thin-walled articles and all applications requiring an excellent surface quality, likewise for paints and varnishes, elastomers or plastics.
