Product Introduction (Profile)
Re-dispersible emulsion powder (RDP/VAE) products are water-soluble re-dispersible powders, divided into copolymers of ethylene/vinyl acetate, vinyl acetate/tertiary vinyl carbonate copolymers, acrylic copolymers and so on, spray-dried and made into powder adhesives, with polyvinyl alcohol as the protective colloid. Such powders can be quickly re-dispersed into emulsion after contact with water. Due to the high bonding capacity and unique properties of re-dispersible latex powders, such as water resistance, constructability and heat insulation, they are used in an extremely wide range of applications.

It has outstanding bonding strength, improves the flexibility of mortar and has a longer open time, gives mortar excellent alkali resistance, improves the adhesion of mortar adhesion, flexural strength, waterproofing, plasticity, wear-resistant performance and constructability, and it has strong flexibility in the flexible anti-cracking mortar. With good water resistance and alkali resistance of dispersible latex powder, the use of the scope of construction adhesives, dry mortar modification, wall insulation and finishing systems, wall plastering adhesive and sealing plaster, powder coatings, construction putty in the field.

 

Classification and Main Indicators of Qingquan Product Models

 

RDP / VAE

Redispersible latex powder (VAE/RDP)

At present, most of the polymer emulsion powder applied in the market is made of vinyl acetate, ethylene, tertiary vinyl carbonate and other monomers with polyvinyl alcohol as the protective gum, through emulsion polymerization to get the parent emulsion, and then spray-dried. As a re-dispersible polymer emulsion powder, first of all, it must be easy to re-dispersed in water and/or alkaline cement mortar, and its performance is basically the same as the parent polymer emulsion performance, which is a prerequisite for its application. Secondly, re-dispersible polymer emulsion powder should have good storage stability, in conventional storage conditions, polymer adhesive powder does not stick, maintain good fluidity.

- Applications -

 

Dispersible polymer emulsion powder is mainly used together with cement and other inorganic binders for modification of concrete, sand, etc. and as powder coatings and powder adhesives. Depending on the specific application, it can be divided into.

Application	Product model	Product features
Mortar putty	CF	Enhance the water retention and waterproofing properties of materials.
	1009	Improve the cohesion of materials
	1006	Improve the weather resistance of materials
	1003	Good compressive strength and wear resistance.

Suitable for ceramic tile adhesive

(1) No damage to the bonding action under mechanical and thermal stresses.
(2) Good hydrolysis resistance.

 

Applied to flooring

Such as floor repair mortar, self-leveling floor mortar, wall and floor tile adhesive and sealing mortar.

1. Improve the compressive/flexural strength of the material.
2. Improve the abrasion resistance of cementitious materials.
3. Does not affect the leveling effect of the material and improve the surface condition.

 

Suitable for wall putty

Improve the adhesion of putty: Latex powder can increase the adhesion of putty, so that it can be more firmly adhered to the surface of the wall. This not only improves the durability of the putty layer, but also prevents the putty layer from falling off and cracking.

 

Suitable for external wall insulation mortar

(1) It can make the mortar have excellent adhesion to cement-based substrate and special substrate with two-way adhesion.
(2)It can durably and stably reduce the elastic modulus of mortar and make the mortar have certain flexibility.
(3) Good resistance to saponification, maintaining long-term flexibility in the mortar.
