Construction Raw Materials HPMC Powder
Hydroxypropyl Methylcellulose (HPMC) is commonly used as a construction additive and is available in powder form. It is used in various construction materials, including but not limited to:
- Tile Adhesives: HPMC is often added to tile adhesives to improve water retention, workability, and adhesion. It helps ensure proper bonding between tiles and the substrate.
- Mortars: In cement mortars, HPMC acts as a thickening agent, providing better workability and sag resistance. It can also enhance water retention and improve the overall performance of the mortar.
- Plasters: HPMC is used in plaster formulations to control the setting time, improve adhesion to substrates, and enhance workability. It contributes to a smoother finish and helps reduce cracking.
- Cement-Based Renders: HPMC can be incorporated into cement-based renders to improve the cohesion of the mix, reduce water absorption, and enhance the overall durability of the coating.
- Self-Leveling Compounds: In self-leveling compounds, HPMC is added to control the flow properties and improve the leveling characteristics of the material.
- Grouts: HPMC is used in tile grouts to improve water retention, workability, and adhesion. It helps prevent shrinkage and cracking in the grout lines.
- White Cement-Based Wall Putty: As mentioned earlier, HPMC can be added to white cement-based wall putty to enhance water retention, adhesion, flexibility, and workability.
