Wall putty(Skim Coat) is a kind of decorative materials to make wall surface smooth, it can be used in exterior and interior wall decoration. SLEOCHEM HPMC plays an essential role in wall putty(skim coat) to improve the key properties like water retention, open time, crack resistance, workability, etc.

Factory-made mortars have been mostly implemented as masonry renderings, fixing tiles, self-levelling floors and so on. When mortar is applied on substrate, water may be absorbed by the substrate. This phenomenon can induce insufficient hydration of cement, and thus decrease mechanical properties of the mortar.

The HPMC mainly plays a role in water retention and thickening, able to effectively improve the bond force and sag resistance of slurry.

With the rapid development of the construction industry, people have increasing demands for new building materials. Due to the increase in people’s awareness of environmental protection and the continuous improvement of construction efficiency,

The greater the viscosity of cellulose ether is, the better the water retention property will be. The viscosity is an important parameter of HPMC performance. At present, different HPMC manufacturers use different methods and apparatus to measure the viscosity of HPMC

HPMC are widely used in dry mix mortar products. The amount of cellulose ether, such as HPMC in dry mortar, added is very low, but it can significantly improve the performance of mortar and is an important additive that affects the construction performance of mortar. Cellulose ethers are rheology modifiers used to adjust the rheological properties of mortar.

In the use of hydroxypropyl methyl cellulose HPMC, we usually find that it is basically divided into two types: immediate and slow dissolution. Let us understand the difference between quick dissolution and slow dissolution of hydroxypropyl methyl cellulose.

Inner wall putty powder is the most common problem after putty construction. To understand the reason of inner wall putty powder, you must first understand the basic raw material components and curing principle of inner wall putty powder,

HPMC endows wet mortar with excellent viscosity, which can significantly increase the bonding ability between wet mortar and base, and improve the anti-sagging performance of mortar. It is widely used in plastering mortar, external wall insulation system and tile bonding mortar.
