HPMC (Hydroxypropyl Methyl Cellulose) is a key additive in construction materials, including tile adhesives, wall putty, plaster, self-leveling compounds, and cement-based mortars. Among its many performance characteristics, viscosity stability is one of the most critical factors affecting workability, adhesion, water retention, and overall product performance.
This article explores why viscosity stability is essential in HPMC products and how manufacturers benefit from consistent, high-quality formulations.
