Frequently Asked Questions
HPMC acts as a water-retention agent and thickener, preventing the mortar from drying too quickly and ensuring that the cement hydrates properly to avoid cracking.
Due to its high viscosity and thickening properties, HPMC increases the cohesion of the mortar, allowing it to adhere to vertical surfaces without sliding down.
Our HPMC is stable within a PH range of 5.0 to 8.0, making it compatible with most construction chemicals and cementitious materials.
Yes, HPMC is frequently used alongside PCE (Polycarboxylate Ether) and RDP (Redispersible Polymer Powder) to create a synergistic effect that optimizes both flow and adhesion.
The gel temperature (typically 60-90℃) determines the thermal stability of the solution; a higher gel temperature ensures the product remains effective in warmer climates.
High fineness (e.g., >96% at 100 Mesh) ensures that the powder dissolves rapidly and uniformly in water, preventing lumps and ensuring consistent viscosity across the mix.
