Product Description

RDP/VAE(Redispersible Polymer Powder/Redispersible Powder)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.
Redispersible Polymer Powder (RDP) is spray dried re-dispersible polymer emulsion latex powder, designed for the construction industry to enhance the properties of dry mortar blends, able to Redispersible in water and react with hydrate product of cement / gypsum and stuffing, form composite membrane with good mechanics intensity. It improves the important application properties of dry mortars, like longer opening time, better adhesion with difficult substrates, lower water consumption.
Redispersible VAE powder HEARST-503M is a product made of vinyl acetate-ethylene (VAE) copolymer emulsion as the main component, via spay drying process into flowable white polymer powder, which can be widely used for dry mixed mortar or powder construction material products.

RDP/Redispersible Polymer powder

1.0 What is RDP

RDP(Redispersible Polymer Powder/Redispersible Powder) or VAE is a water-soluble re-dispersible powder. It is a copolymer of ethylene and vinylacetate. 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.
This VAE Re-Dispersible Polymer Powder Used in construction uses polyvinylalcohol as a protective colloid. By adding landcel RDP, the performance of mortar with cement or gypsum can meet the needs of various constructions.

2.0 How to Choose RDP

VAE Re-Dispersible Polymer Powder (RDP)is produced by spray-drying and water-based 
emulsion, mostly based on vinylacetate and acrylicacid, dissolves in water easily and quickly 
forms emulsion.The main specification is as below, and Ash content , Film tempreture is the key properties.

3.0 How to use RDP(VAE)
Mainly used in ceramic tile adhesive, ceramic tile jointing agent, plastering gypsum, self-leveling mortar, grout material ceramic tile adhesive, bonding mortar exterior insulation system, exterior insulation system of plastering mortar, flexible interior and exterior wall putty, flexible anti-crack mortar, powder polystyrene particles insulation mortar, powder coating, insulation board, have higher request for flexible polymer mortar products.

Product Property
- HEARST-503M as a VAE polymer powder can be redispersed well into polymer emulsion again after mixing with water.
- HEARST-503M with the characteristics of middle glass transition temperature, therefore, has a good balance between adhesion and flexibility, and wide universality of application.
- HEARST-503M 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 with good acid and alkaline resistance, is good for the workability and weatherability of the construction material products which used it.
- HEARST-503M with good and wide compatibility, can use with almost all other chemical additives in diverse formulations.
- HEARST-503M 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 is produced without adding plasticizer, film forming additives or solvent, so it has excellent environmental protection, low odor, low VOC.

Applications and dosage


HEARST-503M is recommended to use in dry mixing mortar or powder construction material products, such as ceramic tile adhesive, tile grout, external wall insulation system (EIFS/ETICS), extrusion mortar for EPS component, waterproofing mortar, self-leveling mortar, repair mortar, decorative mortar, skim coat, fire-resistant mortar, sound insulation mortar, Joint compound, AAC adhesive, gypsum products, etc.
Normally recommended dosage is 0.5~5% in total formulation.

- In EIFS/ETICS formulation, is recommended to add 2~4% dosage of HEARST-503M, which can effectively improve the bonding strength, impact resistance and reduce water absorption.
- In skim coat formulation, is recommended to add 1~5% dosage of HEARST-503M, which can significantly reduce water absorption, improve the flexibility and bonding strength with the substrate.

Application:
1. Dry powder putty: improve the bonding strength, adhesion to the base layer, continuous film formation, dry powder putty is not affected by weather and humidity, making the product more stable, strong alkali resistance, and excellent waterproof performance.
2. Tile adhesive: It has extremely strong adhesion to the wall and bonding strength, which is necessary for high-grade tiles.
3. Tile refurbishment interface agent: good bonding strength, strong adhesion to the base surface of tiles and other surfaces that are smooth and non-absorbent.
4. External wall insulation: bonding mortar, plastering mortar and other construction mortars, especially suitable for flexible construction mortars.
