redispersible latex powder RDP for tile adhesivesDecember 7th 2023
Redispersible latex powder has high flexibility, high weather resistance and high adhesion to various substrates. It is an important additive in dry-mixed mortar, which can improve the elasticity, bending strength and flexural strength of building materials, and reduce Shrinkage rate, effectively prevent cracking.
It plays a significant role in dry cement mortar. It can improve the bonding strength and cohesion of the material. Improve the elastic bending strength and flexural strength of the material. Improve the freeze-thaw resistance of the material. Improve the weather resistance, durability and wear resistance of the material. Improve the hydrophobicity of the material and reduce the water absorption. Improve workability and reduce material shrinkage. Can effectively prevent cracking.
The film of redispersible latex powder is elastic and tough, and it is in the rigid framework formed by the hydration of cement mortar. Between cement mortar particles and particles, it has a function similar to a movable joint, which can withstand high deformation loads, reduce stress, and improve tensile and bending resistance.
Improve impact resistance for thermoplastic resin. The soft film coated on the surface of the mortar particles can absorb the impact of external force, relax without being damaged, thereby improving the impact resistance of the mortar. Improve the hydrophobicity and reduce the water absorption rate, which can improve the microstructure of cement mortar.
The polymer forms an irreversible network during the cement hydration process, and redispersible latex powder is added. Seal the capillary in the cement gel, block the absorption of water, prevent the penetration of water, and improve the impermeability. Improve abrasion resistance and durability.
Redispersible latex powder is mainly used in dry cement mortar in the construction industry and is an important additive for dry cement mortar. Cement dry powder mortar has a significant effect. It can improve the bonding strength and cohesion of the material, increase the elastic bending strength and flexural strength of the material, improve the freeze-thaw resistance of the material, and improve the weather resistance, durability and abrasion resistance of the material. Improve the hydrophobicity of the material, reduce the water absorption, improve the workability, reduce the shrinkage of the material, and effectively prevent cracking. Improve bending and tensile resistance.
