China Used for Concrete Additive Rdp Vae

RDP is mainly used to treat the surface of concrete, aerated concrete, lime sand brick and fly ash brick. When used, water is directly added, and the powder is quickly dissolved in water. Solve the problems that the interface is not easy to stick, the plaster layer is hollow, cracking, peeling and other problems due to the strong or smooth water absorption of these surfaces. It makes the adhesion stronger, not easy to fall off and water resistance, and excellent freeze-thaw resistance. It has a significant effect on simple operation, convenient construction.
RDP products are plentiful in the market, but their properties are basically the same. They can be briefly summarized as follows:
The seed powder can be quickly reduced to an emulsion after contact with water.After the water evaporates, it will form a film, which has high flexibility, high weather resistance and high viscosity to various substrates.
