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.

Product Property
- Better deformability
- HEARST-503M Rdp as a VAE polymer powder can be redispersed well into polymer emulsion again after mixing with water.
- Increased adhesion to a variety substrates
- 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.
- Improved wetting of the substrate
- 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.
- Higher flexural strength and flexibility
- HEARST-503M Rdp with good acid and alkaline resistance, is good for the workability and weatherability of the construction material products which used it.
- Increased impact and abrasion resistance
- HEARST-503M Rdp with good and wide compatibility, can use with almost all other chemical additives in diverse formulations.
- Higher durability and freeze thaw resistance
- 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.

Storage
- Storage should protect from moisture. Ensure that the packaging is intact during transportation, protects from moisture, avoids high temperature and pressure.
-  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.
