RDP powder is a free-flowing and water-soluble white powder which is obtained from vinyl acetate ethylene through spray-drying process. This powder can be quickly dispersed into emulsions after contact with water, because RDP has high bonding ability and unique properties, so their application range is extremely wide. Today we mainly introduce the application of RDP in Tile adhesive.
We give a formula for Tile adhesive
As you can see from the formula of tile adhesive, the dosage of RDP is much larger than that of cellulose ether. In fact, compared with the role of cellulose in the construction phase of tile adhesive , RDP powder products are more important in the long-term stage from construction to the future.
As we all know, RDP powder can be uniformly dispersed in base materials such as cement, and after drying, it forms a flexible and sturdy polymer film. This film is like a bridge that closely connects the tile adhesive with various substrates, greatly improving the adhesion of the tile adhesive to different substrates such as concrete, masonry, ceramics, and gypsum boards. It ensures that the tiles are firmly attached to the base layer and are not likely to fall off.
3.RDP powder also plays the following roles in tile adhesive:
1.Improving Flexibility:
It endows the tile adhesive with good flexibility, enabling the tile adhesive to adapt to the deformation of the substrate and the stress changes caused by thermal expansion and contraction
2.Enhancing Water Resistance:
RDP powder can form a continuous polymer film inside the material. This film can effectively block the intrusion of water and improve the water resistance of the tile adhesive.
3.Improving Construction Performance:
RDP can improve the working performance and operation characteristics of the tile adhesive. It can give the tile adhesive better consistency, extensibility, and open time, making it easier for mixing, application, and tile adjustment.
4.Reducing Sagging and Slipping:
As a rheological modifier, RDP can control the flow and anti-sagging performance of the tile adhesive.
5.Reducing Shrinkage Cracking:
RDP powder helps to reduce the shrinkage of the tile adhesive during the drying and curing process and reduces the risk of shrinkage cracking.
In addition, we know that RDP products have rigid grade and flexible grade, this is due to the different performance requirements of various applications. Generally speaking, Tile adhesive use rigid RDP more.
The benefits of MIKRANT RDP powder from the production side：
1 : Insulation system.
Mikem have 68 tons- storage emulsion tanks with stainless steel materials instead of steel ones. Thermal insulation heating system to sustain stable and persistent production capacity even though under below zero temperature.
2:Waste heat recovery device.
We use waste heat recovery device, which can realize whole process of heat preservation, heat recovery, energy saving 15-20%.
3 : The 4th generation upgraded Atomizer
Fulfil higher solid content with lower energy comsumption than competitors. Supply over 10% of capacities to guarantee suffient output.
4. Advanced R& D laboratory.
We have advanced research and development laboratories and structural models of Sino-US cooperation, which ensure that the quality of our products is always in the leading position.
Let’s sum up, RDP plays an indispensable role in tile tile adhesive products. And the better the quality of the tile adhesive required more RDP powder. Therefore, it is very important to choose a high-quality RDP product. Mikem Chemical has always been committed to creating high-end products, we believe that Mirkant RDP will be your best choice.
