Celpro Mesom 15 is part of the HPMC (Hydroxypropyl Methylcellulose) family of cellulose ethers, renowned for their non-ionic and water-soluble properties. As a medium-viscosity grade, the product is particularly suited for construction needs, where it acts as a thickening, stabilizing, and water-retaining agent. The powder form makes it easily dispersible in mortar mixes, aiding in even distribution and uniform performance. While concentrations commonly vary from 0.1% to 0.5% depending on the specific application, the product's moisture content typically remains under 5-6%, ensuring a stable and consistent formulation. When purchasing Celpro Mesom 15, buyers should specify the required viscosity grade to match their processing needs, and consider packaging options for efficient handling and storage.
