Mortar Additive Redispersible Latex Powder (RDP/VAE)
1.Improve the impact resistance, performance and wear resistance of mortar.
The mortar is filled with cement mortar pore cavity, the compactness of cement mortar is improved and the wear resistance is improved.Under the action of external forces, it can cause relaxation without being destroyed.Polymer paper can be stored in cement mortar management system.
2.Improve the adhesion of mortar construction. Polymer powder particles have wetting effect, so that the two components of cement mortar can flow independently. In addition, rubber powder can induce gas.
3.Improve the bond compressive strength and bond strength of mortar. As an organic chemical adhesive, redispersible latex powder can produce higher compressive strength and compressive strength on different plates.It plays a very important role in the bonding of cement mortar and organic chemical raw materials (extruded insulation foam board) and clean board surface.
Raw materials and depilating polymer powder are widely used in all cement mortar management systems to improve the cohesion of cement mortar.
4.Improve the aging resistance of mortar, resist freeze-thaw cycle, and prevent cement mortar from cracking. The redispersible latex powder belongs to thermoplastic resin and has good flexibility, which can make the mortar deal with the damage caused by the external hot and cold environment, and reasonably avoid cracks in the mortar due to the change of temperature difference.
5.Increase the hydrophobicity of mortar and reduce water content. The redispersible latex powder is demulsified in the cement mortar cavity and surface layer, and the polymer paper is not easy to disperse after water treatment, which blocks the water invasion and improves the impermeability.This kind of water-repellent glass wool has a good effect because of its unique ability to disperse natural latex powder.
