Sillitin Z 89 puriss

Our puriss products set new benchmarks in fineness and quality, surpassing classic Sillitin. With a significantly reduced residue > 40 µm, they minimize abrasive effects and offer critical advantages: processing equipment such as mixers, tools, and nozzles are protected – especially during airless spraying applications.
