Hydroxypropyl Methyl Cellulose HPMC Powder for Cement Based Tile BondFebruary 23rd 2024
Redispersible latex powder is a powder binder made from a special polymer emulsion spray-dried. This powder can be quickly redispersed to form an emulsion after contact with water, and has the same properties as the initial emulsion. Therefore, the emulsion used for the production of redispersible latex powder should also have the following special properties compared with ordinary emulsions directly used for adhesives:
Spray drying can be achieved; the dried latex powder has redispersibility; in addition, the mortar contains alkaline substrates such as cement. Therefore, a certain degree of alkali resistance is also required.
The redispersible latex powder configuration mortar has extremely high compressive shear and shear strength. It has the same durability as concrete and does not fall off. For lightweight walls, cracks can be eliminated, including: wet slab walls. The door window stress cracks and cracks caused by insufficient ridge period are a high-tech product.
What are the benefits of using redispersible latex powder
In the step of decoration to wall decoration, putty powder is used before applying latex paint or wallpaper. In order to improve the adhesion, wear resistance and alkali resistance of putty, more and more construction projects If redispersible latex powder is mixed into putty powder, what exactly is redispersible latex powder and what function does it have?
Redispersible latex powder is a powder binder made from a special emulsion (high molecular polymer) spray-dried.
This powder can be quickly redispersed to form an emulsion after contacting with water, and has the same properties as the initial emulsion, that is, a film can be formed after the water evaporates. This film has high flexibility, high weather resistance and resistance to various High adhesion to the substrate.
Redispersible latex powder is a green, environmentally friendly, building energy-saving, high-quality multi-purpose powder building material, and an essential functional additive for dry-mixed mortar. It can improve the performance of the mortar, increase the strength of the mortar, increase the bonding strength of the mortar and various substrates, and increase the flexibility and variability of the mortar, compressive strength, flexural strength, abrasion resistance, toughness, adhesion Relay and water retention capacity, constructability. In addition, the water-repellent latex powder can make the mortar have good water resistance.
