Detailed HPMC/HEMC Solutions Viscosity Measurement

Accurate viscosity measurement is critical for evaluating Hydroxypropyl Methylcellulose (HPMC) and Hydroxyethyl Methylcellulose (HEMC) performance in construction, coatings, and other industries. In this video, Landu Laboratory presents a full, professional walkthrough of the viscosity testing procedure: 🔹 Precise Sample Preparation: 2% solution concentration Controlled hot/cold water dispersion method for optimal dissolution 🔹 Dissolving Process: High-efficiency stirring techniques Achieving a smooth, bubble-free solution for reliable results 🔹 Constant Temperature Control: Solution stabilized at 20.0°C ± 0.2°C in a water bath Elimination of air bubbles for accuracy 🔹 Viscosity Measurement Using Brookfield RV Viscometer: Proper spindle selection (Spindle #5, #6, or #7 depending on viscosity range) Correct immersion and stabilization techniques Final reading: 22,150 mPa.s for the 2% HEMC solution Learn how to control every critical step to ensure repeatable, professional-quality viscosity measurements. Whether you're developing drymix mortars, tile adhesives, or coatings, mastering viscosity testing is key to material performance. 👉 Subscribe to Landu Laboratory for more expert cellulose ether insights, testing demonstrations, and formulation tips! 👉 Contact us if you need tailored HPMC/HEMC solutions for your industry needs. #CelluloseEther #HPMC #HEMC #ViscosityTesting #BrookfieldViscometer #MaterialScience #ConstructionChemicals #LanduLaboratory #QualityControl #BuildingMaterials
