Cement Based Tile Adhesive Mortars Additives Redispersible Polymer Powder Vae/RdpMay 26th 2023
HPMC manufacturer-Product Performance of Redispersible Emulsion Powder
1. Improve the bending strength and flexural strength of mortar
The polymer film formed by Redispersible Emulsion powder (VAE/RDP) has good flexibility. It can form a film on the gap and surface of cement mortar particles to form a flexible connection, so that the brittle and hard cement mortar becomes elastic. Mortar with redispersible Emulsion powder added has much higher tensile and flexural strength than ordinary mortar.
2. Improve the bonding strength and cohesion of mortar
The Redispersible Emulsion powder as an organic binder can form high tensile strength and bonding strength on different substrates after film formation. It plays an important role in the adhesion of mortar and organic materials (XPS, extruded polystyrene board) and smooth surface substrates. The film-forming polymer powder is distributed in the entire mortar system as a reinforcing material to increase the cohesion of the mortar.
3. Improve the impact resistance, durability and wear resistance of the mortar
The emulsion powder particles fill the cavities of the mortar, and the density of the mortar is increased, and improves the wear resistance. Under the action of external force, it will relax without being damaged. The polymer film can be permanently stored in the mortar system.
4. Improve the weather resistance and freeze-thaw resistance, and prevent cracking
Redispersible emulsion powder is a thermoplastic resin with good flexibility, which can make the mortar respond to changes in the external cold and hot environment, and effectively prevent the mortar from cracking due to changes in temperature.
5. Improve the hydrophobicity of mortar and reduce water absorption
The redispersible emulsion powder forms a film on the mortar cavity and surface, and the polymer film will not disperse twice after encountering water, which prevents the intrusion of water and improves the impermeability.
6. Improve the construction performance of mortar
The polymer rubber powder particles have a lubricating effect, so that the mortar components can flow separately, and the emulsion powder has an inducing effect on air, giving the mortar compressibility and improving the construction performance of the mortar.
