Product Description
RDP (Redispersible Polymer Powder/Rdp Powder) or VAE Powder (Vinyl Acetate Ethylene Copolymer)Redispersible Polymer Powder(Redispersible Latex Powder Redispersible Polymer Emulsion Powder) plays an important role as an additive of building mortar. Adding redispersible emulsion powder to mortar can prepare a variety of mortar products such as tile glue, insulation mortar, self-leveling mortar, putty, plastering mortar, decorative mortar, joint pointing agent, repairing mortar and waterproof sealing material, which expands the application range and application performance of building mortar. Of course, redispersible emulsion powder has adaptability problems with cement, admixtures and admixtures, which should be paid enough attention in specific applications.
The polymer rdp/Redispersible Polymer Powder(redispersible emulsion powder) is physically mixed with other inorganic adhesives (such as cement, hydrated lime, gypsum, clay, etc.) as well as various aggregates, fillers and other additives (such as hydroxypropyl methyl cellulose, polypolysaccharide (starch ether), cellulose fiber, etc.) to make dry mix mortar. When the dry powder mortar is mixed in water, under the action of hydrophilic protective colloid and mechanical shear force, the latex powder particles can be quickly dispersed into water, and enough to make the redispersible latex powder fully film. The different composition of rubber powder has an impact on the rheological properties of mortar and various construction properties: the affinity of latex powder to water when it is redispersed, the different viscosity of latex powder after dispersion, the impact on the gas content of mortar and the distribution of bubbles, the interaction between rubber powder and other additives, so that different latex powder has an effect of increasing fluidity, increasing thixotropy and increasing viscosity.The role of Redispersible Polymer Powder RDP in mortar
Redispersible emulsion powder is mainly used in internal and external wall putty powder, tile binder, tile joint agent, dry powder interface agent, external wall insulation mortar, self-leveling mortar, repair mortar, decorative mortar, waterproof mortar external insulation dry mix mortar. The purpose of the mortar is to improve the weaknesses of traditional cement mortar such as brittleness and high elastic modulus, and to provide cement mortar with better flexibility and tensile bond strength to resist and delay the formation of cracks in cement mortar. Due to the interpenetrating network structure between polymer and mortar, a continuous polymer film is formed in the pores to strengthen the bond between aggregates. Some of the pores in the mortar are blocked, so the performance of the modified mortar after hardening is greatly improved than that of the cement mortar.
Redispersible Polymer Powder RDP is a thermoplastic material, it and inorganic cementing material constitute an ideal bonding system, each component brings its own properties and complement each other, together to form a cement and redispersible adhesive powder alone can not achieve the performance. The application of redispersible adhesive powder to mortar products can improve a variety of properties, such as: improve the bonding force; Improve cohesion; Reduce the elastic modulus; Increase flexural strength: increase flexure; Improve impact resistance; Improve wear resistance: reduce water absorption; Improve constructability: enhance durability; Improve water retention, etc.Technical data | Technical Date | HEARST RD 503M | HEARST RD 760F | HEARST RD 740H | HEARST RD 745W |
