Product Description
Shandong Hearst Building Material Co.,ltdWe have strong financial strength, and introduced full set of production line with industry leading level from German. With foreign advanced technology production base and our research and development center, annual output of 22000tons,now we have become one of the biggest and trusted manufacturer of Redispersible polymer powder in China.RDP/VAE(Redispersible Polymer Powder/Redispersible Powder)RDP (Redispersible Polymer Powder/Redispersible Powder) or VAE is a water-soluble re-dispersible powder. It is a copolymer of ethylene and vinyl acetate. It dissolves in water easily and forms emulsion quickly, RDP could offer strong adhesive and stretching force to improve the workability, flexibility and water-proofing of the materials. Redispersible Polymer Powder is a kind of free-flowing white powder,which is spray-dryed by polymer emulsion and after subsequent treatment to keep the stability of powder appearance and character. The mainly application is in construction dry-mixed mortar,and have excellent performance in increasing the dry mortar cohesion,adhesion and flexibility.The redispersible polymer powder(VAE) is a water-soluble re-dispersible powder. It is a copolymer of ethylene and vinyl acetate. It uses polyvinyl alcohol as a protective colloid. By adding re-dispersible latex powder, the performance of mortar with cement or gypsum as the substrate can meet the needs of various constructions.
Rdp/Redispersible adhesive powder 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.
Product Property - HEARST-503M Rdp as a VAE polymer powder can be redispersed well into polymer emulsion again after mixing with water.- HEARST-503M Rdp with the characteristics of middle glass transition temperature, therefore, has a good balance between adhesion and flexibility, and wide universality of application.- HEARST-503M Rdp can form film with suitable hardness inside and surface of the finished construction material product, which can significantly improve the cohesion, wear resistance, impact resistance and waterproofing ability.- HEARST-503M Rdp with good acid and alkaline resistance, is good for the workability and weatherability of the construction material products which used it.- HEARST-503M Rdp with good and wide compatibility, can use with almost all other chemical additives in diverse formulations.- HEARST-503M Rdp not only retains the superior performances of the original VAE emulsion, such as good film formation, excellent adhesion and durable flexibility, but also improves the convenience and stability for transportation, storage and operation.- HEARST-503M Rdp is produced without adding plasticizer, film forming additives or solvent, so it has excellent environmental protection, low odor, low VOC.Technical data Technical Date | HEARST RD 503M | HEARST RD 760F | HEARST RD 740H | HEARST RD 745W |

The role of redispersible emulsion powder in mortar
Properties:
1. It can improve its adhesion, flexural strength, abrasion resistance and workability.
2. High flexibility and good bonding strength.
3. It has extremely outstanding waterproof performance.
4. Increase the elasticity of the mortar and have a longer open time.
5. Give the mortar excellent alkali resistance.
Redispersible Polymer Powder RDP can improve adhesion,strength in bending,abrasion resistance,de-formability.It has good rheology and water retention,and can increase the sag resistance of tile adhesives,it can made up to tile adhesives with excellent non-slump properties and putty with good properties.
The purpose of redispersible emulsion powder in mortar is to improve the weaknesses of traditional cement mortar such as brittleness and high elastic modulus, and to give cement mortar good 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, continuous polymer film is formed in the pores, which enhances 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.Classify:Redispersible powder for waterproofRedispersible powder for wall puttyRedispersible powder for tile and plaster mortarRedispersible powder for Self-levelingRedispersible powder for diatom mudStorage - HEARST-503M storage should protect from moisture.- At storage temperatures above 30ºC or under pressure during storage may cause HEARST-503M caking occurs.- If HEARST-503M is not used up after opening, it should be sealed in time and used as soon as possible.- The optimal service life of HEARST-503M is 6 montXDD, and the possibility of the product performances beyond the best use period will be reduced.- In order to ensure the best use effect of HEARST-503M, it is recommended to test the product's performances before use.Packaging - 25Kg bag- 600Kg Big Bag- Standard packing: 25kg/bag inner with PE bags- 1*20'FCL: 14 tons with pallets or 17 tons without pallet- 1*40'FCL: 28tons with palletsEnsure that the packaging is intact during transportation, protects from moisture, avoids high temperature and pressure.Our factoryOur laboratoryOur Service- Free Samples- Technical Supports- Every batch of products will be tested to ensure its quality.- Quality Guarantee - Sample testing support.
