Cellulose Ether HPMC Powder for Construction Chemicals to Improve Water Retention
Cellulose Ether HPMC (Hydroxypropyl Methyl Cellulose) powder is a popular additive used in construction chemicals to improve water retention. It is a white, odorless, and tasteless powder derived from cellulose, a natural polymer found in wood pulp.
HPMC functions by:
- Thickening: It increases the viscosity of the mortar or plaster, making it easier to apply and reducing the risk of sagging.
- Water retention: It helps the mortar or plaster retain moisture for a longer period, allowing for proper hydration of the cement and preventing cracks from forming. This is especially important in hot and dry climates where water evaporation is rapid.
- Improved workability: By enhancing workability, HPMC allows for smoother application and better finishing of the construction material.
