Product Description

The important role of HPMC in cement is mainly in three aspects:
1. Excellent water retention capacity,
2. The effect on the consistency and thixotropy of the mortar,
3. Interaction with cement.
The water-retaining effect of cellulose ether depends on the water absorption, composition, layer thickness, water requirement of the base layer, and the setting time of the setting material.
The higher the transparency of HPMC, the better the water retention.
