Redispersible polymer powder is currently mainly used with inorganic binders such as cement to modify concrete, mortar, etc. It can be mixed with hydraulic binders such as cement and gypsum to form a single-component powder premix modified by synthetic resin. When used, only water needs to be added. Adding re-dispersible polymer latex powder to ordinary mortar has many advantages, such as:
1) The strength of the mortar is well-developed and has good adhesion to the matrix, especially high early bonding strength;
2) It has good crack resistance and frost resistance;
3) It has good operating performance and is easy to plaster quickly;
4) The tensile strength of the polymer film is more than ten times greater than that of ordinary mortar, which significantly improves the construction, adhesion, flexibility, deformability, wear resistance, flexural strength, cohesive strength, and durability of the modified material. Therefore, re-dispersible latex powder is widely used in dry-mixed mortar, such as building putty, exterior wall insulation materials, interior and exterior wall decoration materials, floor materials, caulking mortar, standard tile grout, concrete interface mortar, standard repair mortar, standard waterproof sealing mortar, gypsum products, epoxy wear-resistant floor, powder coating, and other fields.
Redispersible polymer powder enhances mortar strength
1. Building putty
The use of building paint to decorate the interior and exterior walls of buildings has become more and more widespread. Still, the paint finishes of many buildings have peeled, cracked, and fallen off after a period of use, destroying the overall beauty of the building. There are many reasons for the above phenomenon, and the building putty used for wall foundation treatment is one of the key factors. Adding re-dispersible polymer latex powder to inorganic binder powders such as cement can improve the comprehensive properties of cement mortar, such as flexibility, water resistance, compressive strength, and bonding strength with other substrates, ensuring the long-term decorative effect of building paint, and the production process is simple, the storage performance is stable. The transportation is convenient, so there is a broad market prospect.
2. External wall insulation materials
The most important performance of polymer-modified bonding mortar in external insulation systems is the bonding strength with substrate or polystyrene board. In the early days, people used ready-to-use adhesives based on polymer emulsion. However, in practice, many problems have arisen, especially when the emulsion adhesive is mixed with cement on site. According to this process, the water-cement ratio cannot be guaranteed to be the same and mixed evenly, so it is impossible to obtain adhesives and primers with stable quality, resulting in substandard product performance. Therefore, people are looking for another system to replace this ready-to-use adhesive. Polymer latex powder not only has good adhesion to the substrate or board but also has sufficient deformability, can disperse shrinkage stress, avoid cracking, and resist impact. Its good hydrophobicity and air permeability prevent water from invading and causing damage to the system while allowing the internal moisture to evaporate in time. They can perform their effectiveness stably and for a long time in various climates, so it is becoming more and more popular.

3. Internal and external wall decoration materials
At present, the main internal and external wall finishing materials are lime paste with lime as the main adhesive. However, the bonding strength between this kind of plaster and the substrate is poor, and it is easy to absorb water and turn white. The addition of re-dispersible polymer latex powder greatly improves its flexural and compressive strength and bonding strength with the substrate. It has good hydrophobicity and air permeability, which well solves the whitening phenomenon and maintains the dryness of the plaster. It is a valuable exterior wall decoration material. In addition, the Redispersible polymer powder is compounded with gypsum and can be used in occasions that require the use of high-quality and high-quality building materials.
4. Self-leveling floor
Floor materials require low shrinkage to prevent cracking, rapid solidification to increase construction speed, etc. At the same time, due to the use of thin-layer construction, polymers need to be added to improve adhesion, wear resistance, and flexural strength. Redispersible polymer powder is not only used to improve the mechanical properties of floor materials but also used as a rheology modifier together with other additives such as methyl cellulose ether and high-efficiency water reducer to improve the fluidity of mortar, reduce water seepage and precipitation, and make self-leveling floor materials.
