Hydroxypropyl methyl cellulose(HPMC) introduction

Hydroxypropyl Methyl Cellulose-HPMC

1.What is hydroxypropyl methyl cellulose-HPMC?

Hydroxypropyl methyl cellulose is a kind of non-ionic cellulose mixed ether. It is a semi-synthetic, inactive, viscoelastic polymer.It is widely used in construction, food, medicine, and other industries.

2.Functions of hpmc in dry-mix mortar? 

Water retention

HPMC has good water retention properties and can effectively prevent the water in the mortar from evaporating too quickly, especially in high temperature or dry environments.

Water retention helps the cement to fully hydrate, thereby improving the strength and durability of the mortar. 

Workability

HPMC can increase the viscosity and lubricity of the mortar, making it easier to construct the mortar and improving the smoothness of operations such as plastering and spraying.

It can also reduce the sag and dripping of the mortar, especially suitable for vertical wall construction.

Increase Bonding Strength

HPMC can improve the bond between the mortar and the substrate (such as bricks, concrete, etc.), reduce hollowing and falling off.

Anti-sagging

When constructing thick layers or vertical surfaces, HPMC can effectively prevent the mortar from sagging or sliding due to gravity, ensuring the quality of construction.
