Redispersible latex powder can improve the bonding strength of building paint putty powder；

The majority of building material customers need to use redispersible latex powder in the production of building paint putty powder. Using these redispersible latex powder can increase bonding strength, but the formula ratio must be appropriate, and the additives inside must be used properly. We use redispersible latex powder to improve its strength, so how can we ensure this strength?

Redispersible latex powder is a spray dried dispersion after 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 producing these latex powders, which need to be carried out under high temperature conditions. If not properly handled, a continuous film will be formed, and even the dispersed solution of the sticky continuous film will be transformed into a flowable powder. Not all dispersed solutions can be transformed into redispersible latex powder.

Firstly, we need to understand what redispersible latex powder is, how it is made, and its main function is to improve its degree. Its components are also polymer emulsions, and various additives are added. At the same time, protective colloids and anti caking agents are added to make the polymer form a powder that can be redispersible and freely flow in water after spray drying.

We mainly use it to produce putty powder and add it to dry mortar. During the production process, the redispersible latex powder can be re dispersed and re emulsified, and then the base layer continuously absorbs the free water in the internal gaps of the mortar. The strong alkaline environment provided by cement allows the latex particles to dry and form a continuous film insoluble in water in the mortar. This continuous film is formed by combining single dispersed particles in the emulsion into a homogeneous body.

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