Redispersible emulsion polymer powders: Innovative material solutions lead the future of coatings industry

(Redispersible emulsion polymer powders: Innovative material solutions lead the future of coatings industry)

Redispersible Emulsion Polymer Powder products are water-soluble dispersible powders, which are divided into ethylene/vinyl acetate copolymers, vinyl acetate/tertiary ethylene carbonate copolymers, acrylic copolymers, etc. agent, with polyvinyl alcohol as a protective colloid. This powder can be quickly redispersed into an emulsion after contacting with water. Due to the high binding ability and unique properties of redispersible polymer powders, such as water resistance, construction and heat insulation, etc., their range of applications is comprehensive.

 

Properties of Redispersible Emulsion Polymer Powder

Redispersible latex powder is a powder formed by spray drying of polymer emulsion, also known as dry powder glue. This powder can be quickly reduced to an emulsion after contact with water and maintains the same properties as the initial emulsion. That is, a film will be formed after the water evaporates. This film has high flexibility, high weather resistance and resistance to various substrates.

Such products are mainly used in external wall insulation, tile bonding, interface treatment, bonding gypsum, plastering gypsum, building interior and exterior wall putty, decorative mortar and other construction fields, and have a vast scope of use and good market prospects.

The promotion and application of redispersible latex powder has greatly improved traditional building materials' performance, adhesion, cohesion, flexural strength, impact resistance, wear resistance, durability, etc. The construction products ensure the quality of construction projects with their excellent quality and high-tech content.

Application of Redispersible Emulsion Polymer Powder

Redispersible latex powder is an indispensable and important functional additive for mixed mortar. It can improve the performance of mortar, increase the strength of mortar, improve the bonding strength of mortar and various substrates, and improve the flexibility and deformability of mortar, compressive strength, flexural strength, abrasion resistance, toughness, adhesion and water retention capacity, and constructability. In addition, the latex powder with hydrophobicity can make the mortar have good water resistance.

 

Masonry mortar, plastering mortar

Redispersible latex powder has good impermeability, water retention, frost resistance, and high bonding strength, which can effectively solve the quality problems such as cracking and penetration between traditional masonry mortars.

Self-leveling mortar, floor materials

Redispersible polymer powders have high strength, good cohesion/cohesion and required flexibility. It can improve the materials' adhesion, wear resistance and water retention. It can bring excellent rheology, workability and best self-smoothing properties to ground self-leveling mortar and leveling mortar.

Waterproof mortar

Redispersible latex powder enhances bonding strength to all substrates, reduces elastic modulus, increases water retention, and reduces water penetration, providing products with high flexibility, high weather, and high water resistance requirements. The long-lasting effect of the sealing system and waterproof conditions.

 

External thermal insulation mortar

Redispersible latex powder enhances the cohesion of the mortar and the bonding force to the thermal insulation board in the external wall thermal insulation system, which can reduce energy consumption while seeking thermal insulation for you. The required workability, flexural strength and flexibility can be achieved in the external wall and external thermal insulation mortar products so that your mortar products can have good bonding performance with a series of thermal insulation materials and base layers. At the same time, it also helps to improve impact resistance and surface crack resistance.

Interface mortar

Redispersible latex powder is mainly used to treat the surfaces of concrete, air-entrained concrete, lime-sand bricks and fly ash bricks, etc., to solve the problem that the interface is not easy to bond, the plastering layer is hollow, cracked, etc., due to excessive water absorption or smoothness of these surfaces, peeling, etc. It enhances the bonding force, is not easy to fall off and is resistant to water, and has excellent freeze-thaw resistance, which significantly affects simple operation and convenient construction.

Effect of polymer ratio of redispersible latex powder on mechanical properties of mortar

1) Within a specific range, the 28-day tensile strength of polymer mortar increases with the increase of rubber powder content. When the rubber powder content is 2.5%, the 28-day tensile strength index of the prepared polymer mortar reaches the maximum value.

2) When the rubber powder content is 2.5%, the high-efficiency water-reducing agent content is 0.6%, and the cellulose ether content is 0.2%, the minimum 28d compression ratio can be achieved; WACKER rubber powder content is 2.5%, the high-efficiency water-reducing ratio is When the water agent content is 0.6%, and the cellulose ether content is 0.1%, the maximum 28d tensile strength can be achieved.

3) Compared with the blank sample, the 28-day compression ratio of the rubber powder polymer mortar was significantly reduced, and the 28-day tensile strength was greatly increased.
