Skim coat (also named by Wall Putty) is a decorative and functional trowelling plaster material for interior or external wall construction. It’s function is to remove uneven defects on the surface of the base materials of wall, and eliminate the stress between different coating layers.

HPMC in Tile Adhesive Application Guide

-Adjust the opening time of tile adhesive: HPMC will form a film on the surface of tile adhesive to reduce water evaporation. Help tile adhesive to increase the open time.

HPMC is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protective colloid properties of surface activity and maintain moisture function properties ect.

With the rapid development of the construction industry, there is a growing demand for new building materials. Due to the increasing awareness of environmental protection and the increasing efficiency of construction, gelling materials and plaster products have been developed rapidly. The most common plaster products nowadays are gypsum plaster, adhesive plaster, embedded gypsum and tile adhesives.

Cement-based tile adhesive is an adhesive used to bond tiles to various substrates. HPMC is an essential component in the formulation of tile adhesives. Whether it is basic tile adhesive or high-quality tile adhesive, HPMC plays an important role.

HPMC is a non-ionic hydroxypropyl methyl cellulose. It is the most commonly used water retaining agent in cement/mortar applications. It is less expensive than other types of cellulose ethers and is widely used in dry mortars.

HPMC can be tailored to the viscosity and gel time required to improve the quality of your product. Increase the viscosity of the product system to achieve the desired physical properties, change the product flow to achieve the desired appearance, increase product solids content to reduce material cost, and prevent paint sagging and ensure mechanical properties and stability.

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.
