How does the putty powder additive redispersible latex powder improve the bond strength?

In the production of putty powder, we need to use redispersible latex powder. The use of these latex powders can increase the bonding strength. We know that if we want to produce high-quality putty powder, the formula ratio must be appropriate, and the additives in it must be used appropriate. We use redispersible latex powder to improve strength, so how can we ensure this strength?

First of all, we need to understand what redispersible latex powder is and how it is made. Its main function is to improve the strength. The composition is also made of polymer emulsion and then various additives are added. At the same time, protective colloid and anti-caking agent are added. The polymer is spray-dried to form a free-flowing powder that is redispersible in water. We are mainly used to produce putty powder and add it to dry powder mortar.

During the production process, the redispersible latex powder can be redispersed and re-emulsified, and then the base layer continuously absorbs the free moisture in the internal voids of the mortar and consumes continuously, and the strong alkaline environment provided by the cement makes the latex particles dry and form in the mortar. A continuous film insoluble in water formed by the fusion of monodisperse particles in an emulsion into a homogeneous mass.

After dispersion, the redispersible latex powder is a spray-dried dispersion, which is added to water to form a stable dispersion with the same properties as the original dispersion. However, there are certain conditions for the production of these latex powders. It needs to be carried out under high temperature conditions. All dispersions can be converted into redispersible latex powders.

Redispersible latex powder can also improve construction performance, and it is also a very important role to make the putty powder and dry mortar we produce better in construction. After the addition, the scratch resistance and flexural strength of the mortar are also improved, which can make the mortar more plastic and less curable.
