VAE Redispersible Polymer Powder

It is a type of re-dispersible emulsion powder copolymerized with VAC/E formed after centrifugal spraying and drying. It dissolves in water easily and quickly. Its chemical properties are the same as original emulsion completely. As the external wall of heat preservation to bond the mortar powder for special uses. it has many advantages, such as simple ingredients, easy uses, low costs and stable performance.

In the exterior wall putty powder, the redispersible polymer powder RDP must be added to play the role of toughness and later strength in the putty powder, so as to prevent the putty powder from peeling off in the later stage.

We know that we need to add cellulose ether to putty powder, but many customers do not know that they need to add RDP, because it is necessary to add RDP to increase costs. Therefore, in order to save costs, many customers do not add it, which is why putty is easy to pulverize and has quality problems. This is the key to the chalk problem.

Cellulose ether plays a water retaining role in putty powder. The dried putty has only a certain strength for the time being, but it will slowly pulverize after a long time, which is closely related to the molecular structure of cellulose ether itself. This kind of putty is loose, with high water absorption, easy to pulverize, no strength and no elasticity. If you want to improve the above problems of putty, you can adjust the putty formula and add some RDP to improve the strength of putty powder.

 

HPMC for Tile adhesive.

Why cellulose ether HPMC is Very Important for tile adhesive ?

Hydroxypropyl methyl cellulose (HPMC) for tile adhesive, also known as ceramic tile bond Thickening agent ,Chemical additivestile glue, is mainly used for pasting ceramic tile, face brick, floor tile and other decorative materials, widely used in internal and external walls, ground, bathroom, kitchen and other building decoration places. Its main characteristics are high bonding strength, water resistance, freeze-thaw resistance, good aging resistance and convenient construction, is a very ideal bonding material.

Functions of cellulose ether HPMC :

Tile adhesive (HPMC for Tile adhesive) is currently one of the important applications of Cellulose ether HPMC construction grade. It uses cement and other organic or inorganic additives as the main cementing material, supplemented by aggregates, water-retaining agents, early strength agents, redispersible polymer powders, etc. Importance of HPMC for tile adhesive

 

Excellent water retention

Develop viscosity (Very sticky)

No anti-sag property

No slip resistance.
