Description&#;

emox Redispersible polymer powder (RDP) is usually used together with Kemox cellulose ether products to modify the property of building mortars.

 

Product details:

Kemox Redispersible polymer powder (RDP) is a free-flowing, white powder obtained by spray-drying of an aqueous vinyl acetate-ethylene(VAE) copolymer dispersion, uses polyvinyl alcohol as a protective colloid., It offers all the advantages of a free-flowing powder additive such as ease of transportation, storage, and handling.

It can be applied in a variety of applications in the construction industry to improve the key properties of cement and gypsum-based formulations.

 

Features:

Kemox polymer powders combine the adhesion of vinyl acetate with the flexibility of ethylene. The powders can be quickly redispersed into an emulsion after contact with water, and the emulsion has the same properties as the original dispersion. When the powder is emulsified and dispersed in water, it will form a polymer film after the water evaporates, This film has high bonding ability and unique properties, such as high flexibility, high heat resistance, and high adhesion to the various substrates.

 

Is Your Wall Putty Okay In Hot And Humid Weather?

Summer is coming, and most construction in high-temperature weather will have a big problem, especially in the treatment of the base layer of the wall, scraping the putty.

 

We know that the best temperature for the construction environment of wall putty is within 5-35 &#;, the humidity in the air is less than 85%, and the humidity of the substrate is less than 10%. So in the hot summer, What&#;s the problem, and how to avoid it?

 

1. high temperature exposure

The temperature is too high in summer, not only the substrate is easy to dry, but also absorbs water quickly, and the strong sunlight will also speed up the evaporation of wall putty moisture. The surface of the putty after construction dries too fast, and the phenomenon of rolling skin, falling powder, and cracking after batch scraping occurs.

 

2. Rainy and tidal

Prolonged wet weather, high air humidity, or high moisture content in the base layer will also affect the drying speed of the putty. If the current layer of wall putty is not dried and the next layer is applied, it is easy to cause bubbling and peeling of the finishing layer. In addition, A humid environment will cause the strength of the water-resistant putty to rise faster and the sandable time to be shortened.

How to solve the problems caused by hot and humid weather?

1. Ensure that the base layer of the wall is well handled

The base layer does not crack, drop powder, or sand is not hollow, and has no old coatings with poor adhesion.

Wall cleaning: no dust, no mildew spots, no salt precipitates on the surface.

The facade is vertical, square, and without missing edges and corners, and the depth of the grid joints is consistent and horizontal and vertical.

2. Take precautions

In a high temperature and dry environment, the interface agent can be used to seal the substrate, or before the wall putty is applied, the wall should be wetted with water two hours in advance, and the wall putty layer should be completely dried and maintained.

It is recommended to use up the prepared wall putty immediately after construction.

Avoid construction in high temperature environments and strong direct sunlight.

 

Summary

In hot weather, the better the quality of putty, the fewer these problems will occur. And the additives used in the putty directly determine the performance. Kemox as a professional construction Chemical manufacturer, provide high-quality Cellulose ether product HPMC &#;hydroxypropyl methylcellulose&#;with Kemox Brand, for wall putty application&#; our grade KP-100K is specially developed for high weather & temperature.

Redispersible Polymer Powder (RDP)

Other names: Redispersible Emulsion Powder,RDP powder,VAE powder,Latex powder,dispersible polymer powder

Redispersible Polymer Powder (RDP) is a redispersible emulsion latex powder produced by spray-drying special water-based emulsion, mostly based on vinyl acetate and ethylene.
After spray drying, VAE emulsion is turned into a white powder which is a copolymer of ethyl and vinyl acetate. It is free-flowing and is easy to emulsify. When dispersed in water, it forms a stable emulsion. Possessing the typical characteristics of VAE emulsion, this free-flowing powder offers greater convenience in handling and storage. It can be used by mixing with other powder-like materials, such as cement, sand and other lightweight aggregate, and it can also be used as a binder in building materials and adhesives.
Redispersible Polymer Powder (RDP) dissolves in water easily and quickly forms emulsion.It improves the important application properties of dry mortars, longer opening time, better adhesion with difficult substrates, lower water consumption, better abrasion and impact resistance.
Protective colloid olyvinyl alcohol
Additives : Mineral anti-block agents
