Questions about You Should Know about HPMCMarch 23rd 2023
1. Improve flexural strength and bending strength of mortar
The polymer film formed by Redispersible polymer powder has good flexibility. A film is formed in the gaps and surfaces of the cement mortar particles to form a flexible connection. So that the brittle and hard cement mortar becomes elastic. The mortar added with Redispersible polymer powder is several times higher in tensile and flexural resistance than ordinary mortar.
2. Improve the bonding strength and cohesive strength of mortar
The Redispersible polymer powder as an organic binder can form a film with high tensile strength and bond strength on different substrates. It plays a very important role in the adhesion between mortar and organic materials (EPS, extruded foam board) and substrates with smooth surfaces. The film-forming polymer powder is distributed throughout the mortar system as a reinforcing material to increase the cohesion of the mortar.
3. Improve impact resistance, durability, abrasion resistance of mortar
The polymer powder particles fill the cavities of the mortar, the density of the mortar increases, and the wear resistance is improved. Under the action of external force, it will relax without being damaged. The polymer film can exist permanently in the mortar system.
4. Improve the weatherability, freeze-thaw resistance of mortar and prevent mortar cracking
Redispersible latex powder is a thermoplastic resin with good flexibility, which can make the mortar respond to changes in the external hot and cold environment, and effectively prevent the mortar from cracking due to changes in temperature difference.
5. Improve the hydrophobicity of mortar and reduce water absorption
The Redispersible latex powder forms a film in the cavities and surfaces of the mortar, and the polymer film will not disperse again after encountering water, which prevents the intrusion of water and improves the impermeability. Special Redispersible polymer powder with hydrophobic grade, better hydrophobic effect
6. Improve workability of mortar
The redispersible polymer powder has a lubricating effect between the particles, so that the components of the mortar can flow independently. At the same time, the redispersible polymer powder has an inductive effect on the air, giving the compressibility of the mortar and improve workability of the mortar.
