Hydroxypropylmethylcellulose

More than 95% of construction-grade hydroxypropyl methylcellulose is used in putty powder mortar. Its functions are thickening, water retention and construction. The water retention performance of HPMC prevents the slurry from cracking due to drying too quickly after application , enhance the strength after hardening, the main function is water retention, thickening, and anti-sagging effects. It can be used as an adhesive in plaster, gypsum, putty powder or other building materials to improve spreadability and prolong operating time; such as ceramic tiles, marble, plastics Decoration: As a paste enhancer, it can also reduce the amount of cement; for anti-crack mortar, add some polypropylene anti-crack fiber (PP fiber) in an appropriate amount, so that they exist in the form of barbs in the mortar, so as to achieve the anti-crack effect. HPMC only plays the role of water retention, thickening and anti-sag.

1. Construction mortar plastering mortar

High water retention can make the cement fully hydrated, significantly increase the bond strength, and at the same time, it can appropriately increase the tensile strength and shear strength, greatly improve the construction effect and improve work efficiency.

2. Water-resistant putty

In putty, hydroxypropyl methylcellulose cellulose ether mainly plays the role of water retention, bonding and lubrication, avoiding cracks and dehydration caused by excessive water loss, and at the same time enhancing the adhesion of putty and reducing sag during construction Phenomenon, so that the construction is relatively smooth.

3. Plaster plaster series

Among the gypsum series products, hydroxypropyl methylcellulose cellulose ether mainly plays the role of water retention and lubrication, and at the same time has a certain retarding effect, which solves the problems of drum cracking and initial strength failure during construction, and can be extended operating hours

4. Interface agent

It is mainly used as a thickener, which can improve the tensile strength and shear strength, improve the surface coating, enhance the adhesion and bonding strength.

5. Exterior wall insulation mortar

In this material, hydroxypropyl methylcellulose cellulose ether mainly plays the role of bonding and increasing the strength, making it easier to coat the mortar and improving work efficiency. Increase the working time of mortar, improve shrinkage and crack resistance, improve surface quality, and increase bond strength.

6. Tile adhesive

The high water retention does not need to pre-soak or wet the tiles and the base, which can significantly improve their bonding strength. The slurry can have a long construction period, is fine and uniform, and is convenient for construction. It also has good moisture resistance.

7, caulking agent, pointing agent

The addition of hydroxypropyl methylcellulose cellulose ether makes it have good edge bonding, low shrinkage and high wear resistance, which protects the base material from mechanical damage and avoids the damage caused by penetration to the entire building. Influence.
