Knowledge of using hydroxypropyl methylcellulose
1
Construction mortar and plastering mortar: High water retention can fully hydrate cement. Significantly increase bonding strength.
At the same time, it can appropriately increase the tensile strength and shear strength. It greatly improves the construction effect and the work efficiency.
2
Water-resistant putty: In the putty, hydroxypropyl methylcellulose mainly plays a role of water retention, adhesion and lubrication.
Avoiding cracks and dehydration caused by excessive water loss, while increasing the putty’s adhesion. It reduces the sagging phenomenon during construction and makes construction smoother.
3
Stucco gypsum series: In the gypsum series products, hydroxypropyl methylcellulose mainly plays the role of water retention, thickening and lubrication.
At the same time, it has a certain retarding effect, which solves the problems of drum cracking during construction and the initial strength cannot be reached, which can extend the working time.
4
External wall insulation mortar: hydroxypropyl methylcellulose plays a key role in this material to increase adhesion and strength. It makes the mortar easier to apply and improves work efficiency.
At the same time, it has anti-sagging effect and higher water retention performance can prolong the working time of the mortar.
Improve anti-shrinkage and crack resistance, improve surface quality, and improve bonding strength.
5
Tile adhesive: high water retention can avoid the need to soak or wet the tile and base in advance. It can significantly improve its bonding strength. The slurry can be used for a long period of construction, delicate, uniform, convenient construction, and has good resistance to migration.
6
Latex paint coatings: In the coatings industry, hydroxypropyl methylcellulose can be use as a film-forming agent, thickener, emulsifier and stabilizer.
It is qualitative to make the film have good abrasion resistance, uniform coating, adhesion, and improve surface tension.
It also has a good miscibility with organic solvents, and its high water retention performance makes it good in brushability and leveling.
