Redispersible polymer powder is the main additive for dry powder ready-mixed mortar such as cement-based or gypsum-based.

1. Mix redispersible polymer powder with water in a ratio of 1:5, stir evenly and let it stand for 5 minutes, then observe the sediment on the bottom layer. Generally, the less sediment, the better the quality of RDP.

Redispersible polymer powder(RDP) is a water-soluble redispersible powder, which is a polymer of butadiene and vinyl acetate, and uses acrylic emulsion as a maintenance colloid solution. Therefore, RDP is very popular in the construction industry sales market, and the inappropriate use of RDP leads to unsatisfactory actual effects of engineering construction.

Redispersible polymer powder (RDP) is made from polymer emulsions by a spray drying process. After mixing with water in the mortar, the polymer emulsion emulsifies and disperses, becoming more stable. RDP emulsifies and disperses in water

Bonding mortar is the most important mortar in the cement mortar series. According to its use, it can be divided into tile bonding mortar, polystyrene board bonding mortar, and extruded board bonding mortar, thermal Insulation Systems.

As a covering material for buildings, ceramic tiles are popular among people. In addition to providing decorative surfaces with aesthetic usage, ceramic tiles are also resistant to water, hard, hygienic and easy to clean. However, the problem of tile peeling,

The thermal insulation board supporting mortar is an important part of the external wall insulation, mainly the thermal insulation board adhesive and protective mortar. As a supporting material for the system, the components of the external insulation system must be regarded as a whole.

Applying RDP into mortar is actually the modification of ordinary mortar, also known as polymer modified cement mortar. Through polymer modification, the brittleness, high elastic modulus and other weaknesses of traditional cement mortar are improved;

After dry-mixed mortar added with redispersible polymer powder is mixed with water, the modification of redispersible polymer powder on cement mortar is accomplished by redispersion of powder, hydration of cement and film formation of polymer.
