Redispersible Polymer Powder Construction Mortar Additives

Redispersible Emulsion Powder
 
Redispersible emulsion powder is mainly applied for the dry cement mortar of the construction industry, and is the important additive of dry cement mortar. 

Redispersible emulsion powder has obvious functions in the dry cement mortar.
1. It can improve the bonding strength and bonding force, the elastic bending strength and rupture strength of the materials.
2. It also can improve the freezeproof property, weathering resistance, durability and 
wear resistance of the materials.
3. As well as intensify the hydrophobicity and reduce the water absorption, improve the construction characteristic and reduce the contraction ratio of materials. The powder can efficiently prevent cracking. 

Improvement of the bonding strength and bonding force 
1. It is quite necessary to add redispersible emulsion powder to the products of dry cement mortar.
2. It can obviously improve the bonding strength and bonding force of materials, as it is because the matrix hole and capillary penetration of the polymer particle to cements form into fine bonding strength after hydrating of the cements.
3. Furthermore, due to the fine bonding force of polymer resin, the powder has better effects on improving the bonding force of dry cement mortar to the basis materials, especially improving the bad bonding property of the inorganic bonder such as cement to the organic materials like woods, fiber, PVC and EPS.
