Thermal insulation board system, generally including ETICS (EIFS) (External Thermal Insulation Composite System / Exterior Insulation Finish System),in order to save cost of heating or cooling power, a good bonding mortar needs to have: easy to mix, easy to operate, non-stick knife; Good anti-hanging effect;

The consistency of wet-mixed masonry mortar is mainly determined by such factors as the type of block material, climatic conditions for construction, distance and conditions of transport, of which the type of block material is the main factor, related to the property and size of block material.

When mastic powder and cellulose ether are present together in wet mortar, some data models show that mastic powder has stronger kinetic energy to adhere to cement hydration products and cellulose ether is more present in the interstitial fluid, affecting the viscosity and setting time of the mortar more.

Redispersible polymer powder(RDP) and other inorganic adhesives (such as cement, slaked lime, gypsum, clay, etc.) and various aggregates, fillers and other additives (such as hydroxypropyl methyl cellulose, starch ether, cellulose fiber, etc.) After physical mixing, dry-mix mortar is made.

Wall putty is a kind of dry mix mortar products which is made of white cement mixed with other additives. It is applied to the wall to fill the cracks,imperfections, and gaps in the wall to create an even base for your paint. Normally wall putty means the plaster on interior wall.

The amount of HPMC used in practical applications is affected by the climate, temperature, local ash calcium quality, the formula of putty powder and the quality required by customers, but there are differences in different regions, generally speaking, it is between 4-5 kg.

Hydroxypropyl methyl cellulose is a kind of nonionic cellulose ether, which is made from natural plant macromolecular cellulose through a series of chemical processing. It is an odorless, tasteless, non-toxic white powder. Soluble in cold water and organic mixtures.

HPMC is widely used in building materials, coatings, synthetic resins, ceramics, medicine, food, textile, agriculture, cosmetics, tobacco and other industries. HPMC can be divided into: construction grade, food grade and pharmaceutical grade according to the application.

Hydroxypropyl methyl cellulose HPMC can be widely used in concrete, brick wall, block, gypsum wallboard, cement board and other substrate surface and ceramic tile, floor tile, wall brick, Mosaic, marble, culture stone and other direct paste materials.
